Time-Varying Income and Price Elasticities of Oil Demand in OECD Countries

This study examines the long-run income and price elasticities of oil demand in 21 OECD countries using quarterly data from 1980:Q1 to 2021:Q3. We find that oil demand is inelastic with respect to both income and prices at 0.117 and −0.179, respectively. The cointegration tests reveal instability in oil price elasticities over time. The time-varying panel data estimates support these findings, showing significant variations in elasticities influenced by oil market dynamics and global events. Income elasticities reached their highest levels during the COVID-19 pandemic, while price elasticities ranged from −0.396 to 0.275. Significantly, the sign of oil price elasticities shifted from negative to positive after 2015, contrary to the law of demand, probably because of declining oil prices during that period. The largest positive and statistically significant price elasticity occurred in early 2020, which can be attributed to the COVID-19-induced decline in oil prices. Overall, this analysis contributes to understanding oil demand dynamics and highlights the impact of economic and oil market factors on elasticities.

Converting lignocellulosic biomass into valuable end products for decentralized energy solutions: A comprehensive overview

This review manuscript delves into lignocellulosic biomass (LCB) as a sustainable energy source, addressing the global demand for renewable alternatives amidst increasing oil and gas consumption and solid waste production. LCB, consisting of lignin, cellulose, and hemicellulose, is versatile for biochemical and thermochemical conversions like anaerobic digestion, fermentation, gasification, and pyrolysis. Recent advancements have led to a 25 % increase in bioethanol yields through alkali pre-treatment and optimized fermentation, a 20 % enhancement in microbial delignification efficiency, and a 35 % improvement in enzyme efficiency via nanobiotechnology. These innovations enhance biofuel production sustainability and cost-effectiveness. Decentralized energy systems utilizing locally produced biomass can reduce transmission losses and greenhouse gas emissions by up to 30 %, fostering community energy independence. These developments significantly contribute to global sustainability and socio-economic development by converting waste into valuable energy, promoting environmental stewardship, and supporting economic resilience. Furthermore, this review also discusses innovative strategies to address technological, economic, and environmental challenges and highlights the role of decentralized solutions in promoting sustainable energy production.

Green Energy Transition: Evaluating Carbon-To-Liquid Technologies for 2050 Climate Goals and Energy Security

China's coal-to-liquid (CTL) sectors must quickly adjust to a low-carbon economy to meet the energy demand while mitigating environmental and energy security challenges. Similarly, China's climate goals for 2050 are gravely jeopardized if the industry's enormous ecological impact is not addressed. This research develops a conceptual framework for environment-security-economic evaluation of the high-carbon energy sector. Moreover, it constructs a system dynamics material model to predict the upgrade plan's industrial capacity and carbon emission scale. Finally, it calculates the dynamic optimal deployment scale at various epochs based on the sequential decomposition goal of "carbon peak" and "carbon neutrality." These measures are needed to anticipate the development of China's CTL industry. The road map predicts that by 2025, China's CTL industry will be able to meet at least 5% of the country's total oil demand. The adoption of scale A process will improve the economic and environmental performance of the CTL industry due to the cost savings and efficiency gains at a larger scale. In addition, the industry's overall energy efficiency will rise in 2023 and exceed 50% after 2035. Findings indicate that the CTL sector will approach a carbon peak in 2029 and neutrality and transition to hydrogen generation by 2050.

Drugs and other substances aggravating acne vulgaris

Introduction and Purpose This review explores several factors exacerbating acne, including the supplementation of vitamins B6 and B12, the impact of red ginseng oil, dairy and whey product consumption, iodine association, anabolic-androgenic steroids, alcohol abuse, and the influence of progestin contraceptives. Material and methods This review is based on articles from the PubMed database, covering the years 2018-2023, using keywords: acne vulgaris, acne vulgaris aggravation, substances aggravating acne vulgaris. Results High doses of B6 and B12 have been reported to worsen acne, potentially linked to their prolonged use. Red ginseng oil, believed to have numerous health benefits, may exacerbate acne symptoms by increasing inflammatory biomarkers. Dairy consumption, specifically casein and whey proteins, is associated with increased insulin-like growth factor 1, contributing to acne aggravation. Iodine has been extensively linked to acneiform eruptions, and its correlation with dairy consumption is hypothesized. Anabolic-androgenic steroids, found in muscle-building supplements, elevate sebum production and may cause acne fulminans. Alcohol abuse further intensifies acne symptoms by impacting testosterone levels, promoting proinflammatory cytokine production, and altering the skin microbiome. Progestin contraceptives, particularly levonorgestrel and etonorgestrel, exhibit androgenic properties that may increase sebum production and potentially aggravate acne. Conclusions Understanding and identifying these exacerbating factors are crucial for healthcare providers to enhance anti-acne therapy outcomes, emphasizing the importance of not only treating but also preventing the escalation of acne manifestations in patients.

Exploring Alkali Hydroxide Influence on Calcium Titanate Formation for Application in Biodiesel Catalysts

Biodiesel has been recognized as the most widely utilized biofuel around the world due to its significant role in reducing the consumption of crude oil and lowering environmental pollution levels. By serving as a renewable alternative to fossil fuels, bioethanol helps decrease greenhouse gas emissions and contributes to a more sustainable energy future. Traditionally, alkali hydroxides like NaOH and KOH have been mainstays in biodiesel synthesis. However, their overuse can lead to unwanted byproducts and operational complexities. Since calcium titanate can occur at a strong base condition, it presents an alternative avenue worth exploring. In this study, we investigate the influence of alkali hydroxides, namely LiOH, NaOH, and KOH, on the formation of calcium titanate through hydrothermal methods, with varying heating times. We aim to understand how different hydroxides affect the synthesis process and the resultant properties of calcium titanate. We delve into the vibrational properties of Ca‒O‒Ti and Ti‒O bonds using Fourier transform infrared spectroscopy (FTIR), confirming the presence of calcium titanate (JCPDS No.42-0423) through X-ray diffractometry (XRD). This thorough characterization provides insight into the structural integrity and composition of the synthesized materials. Moreover, scanning electron microscopy (SEM) reveals the intriguing cube-like morphology of calcium titanate, offering visual evidence of its unique structure. The fatty acid methyl ester Iimpressively, our results show that calcium titanate synthesized in 7 M NaOH and KOH solutions, heated for 24 hours, emerges as a promising biodiesel catalyst. We observe fatty acid methyl ester provides the percentages of 63.67% and 90.02%, respectively, indicating the catalytic efficacy of these materials in biodiesel production. These findings not only contribute to the understanding of calcium titanate synthesis but also pave the way for a sustainable future in biodiesel production by introducing efficient and eco-friendly catalysts.

Fatty acid profiling of bottle gourd [<i>Lagenaria siceraria </i>(Mol.) Standl.] seed oil using gas chromatography-mass spectrometry

The present investigation was carried out to study the oil quality and estimate fatty acid (omega-3 and omega- 6) composition in bottle gourd using gas chromatography-mass spectrometry. Results indicated that the extracted bottle gourd seed oil was estimated to have an oil content (25.2%), polyunsaturated fatty acids viz., omega-3 (6.63%), omega-6 (69.74%) and others (0.17%), which play a major role in, cardiovascular health and has anti-inflammatory, anti-allergic and anti-cancer benefits. It also consisted of saturated fatty acids viz., palmitic acid (9.78%), stearic acid (4.45%) and others (0.97%) along with monounsaturated fatty acids (MUFA) (5.99%) without oleic acid (omega-9). Due to increased demand for specialty edible oil in both domestic and industrial use, it becomes necessary to exploit the potential of bottle gourd seeds as a novel source of edible oil. Being a rich source of omega-6 and omega-3 fatty acids, which lacks omega-9 known for oxidative stability required for storage and cooking, it can be commercialized as cooking oil by blending it with edible oil rich in oleic acid or can also be supplied as an omega-6-rich capsule as a food supplement in future.

Factors Affecting Export Demand for Malaysian Palm-Based Finished Products

The encouraging growth in volume and exports of palm-based finished products (PBFP) was directly related to an increase in their demand. It is thus important to investigate the factors influencing such demand. Our study attempts to elucidate this for the Malaysian PBFP in 10 major foreign markets, namely, Turkey, China, Iraq, Iran, Singapore, Romania, Australia, Pakistan, Russia, and Saudi Arabia. This study constitutes a panel data analysis for the 10 countries using data from 2007 to 2021 using the fully modified ordinary least squares (FMOLS) method. Pedroni and Westerlund cointegration test indicates the presence of a long-term relationship between the variables under study. The empirical results show that gross domestic product (GDP) has a long-term positive influence on the demand for PBFP, with every 1% increase in GDP will increase the demand for palm oil by 0.9%. In addition, population size (POP) also shows a positive sign and is statistically significant at the 1% level, indicating that a 1% increase in POP will lead to a 0.3% increase in PBFP demand. Substitute oil price also has a long-run positive influence where for every 1% increase in the price of both commodities will increase the demand for PBFP by 0.1%. Meanwhile the price of PBFP has a long-term positive influence on its demand. Thus, information regarding the factors influencing the demand for PBFP from our findings may help industry player and policymakers in formulating strategies to improve the markets, and academicians may also benefit from sharing the knowledge gained from the study.

PlaBacter: Determination of Microbial Diversity on Plastic Polymers in Topçu Pond

Climate change is one of the biggest problems of our world, and one of the biggest measures taken to solve the climate crisis is to reduce the consumption of oil and oil derivatives, which are considered among fossil resources. However, with the globalising world and increasing population, oil companies have turned to the plastic and packaging sector in order to meet the increasing demand for plastic consumption. This situation inevitably increases the environmental damage of plastic waste. In particular, the inability to use water resources correctly and the pollution of water by wastes left in the environment adversely affect the lives of living things on earth. Within the scope of the study, it was aimed to determine the microbial diversity living on polyethylene terephthalate (PET), which is known as the raw material of tools such as plastic bottles, food containers, and fishing line, which are left as waste in the environment, especially in rivers and lake shores. In this context, Topçu Pond, which is an important water source in the field of agricultural irrigation in Yozgat province, was selected as the study area. Genomic DNA (gDNA) was isolated from biofilm layers formed on water, sediment, and PET samples collected from the study area. The bacterial communities living in the samples were identified by analysing the 16S rDNA of the gDNAs with the next-generation sequencing method. Thus, we conducted the first microbial diversity study in Topçu Pond and defined the bacterial composition on PET samples in the pond.

Maximization of Biodiesel production from oil that produced during salmon smoking process with high amount of omega-3 by using homogenous catalyst.

The escalating global demand for oil, coupled with declining fossil fuel production, prompts the urgent exploration of renewable alternatives. To address this challenge, researchers are actively seeking environmentally friendly fuels like biodiesel. Among potential feedstocks, oil that is produced from salmon smoking process during industry emerges as a promising option. Smoked salmon oil could be a challenge when producing biodiesel due to its high content of omega-3 compounds. Using homogenous commercial catalyst from alkali to achieve the highest yield from salmon smoking oil was the aim of the current study. A Box-Behnken design and response surface methodology in Design Expert software (version 13) was used to study the effect of four main factors on the biodiesel yield from salmon smoking oil. The optimum biodiesel values were 70°C, 90 min, 0.753 wt.%, and 20 wt.% for temperature, reaction time, sodium hydroxide concentration, and methanol concentration, respectively. At these optimum values, the highest biodiesel production was 92.0% with fatty acid methyl ester contents of 83.4% and conversion efficiency of 77%. Thin-layer chromatography and thermal gravimetric analysis confirmed the successful production of biodiesel at optimized conditions. Using Aspen Plus simulation software confirmed the cost-effectiveness of the homogenous catalyst used for enhancing biodiesel production from salmon smoking oil.

Analyzing the Determinants of U.S. Residential Energy Usage and Spending: A Machine Learning Approach

This study explores the factors that impact residential energy usage and spending in the United States. Using data from the 2020 Residential Energy Consumption Survey (RECS), we investigate the significance of different energy consumption determinants at various analysis levels. Our analysis covers residential energy usage, electricity, natural gas, propane, and fuel oil consumption. We also examine energy usage for space heating, cooling, and water heating. To leverage the extensive RECS data, which includes over 180 variables, we utilized machine learning (ML) techniques for feature selection and determined their Shapley contribution for different target outcomes. Our results indicate that the CatBoost algorithm outperforms other ML techniques on the 2020 Residential Energy Consumption Survey sample. Our findings demonstrate that it is not appropriate to aggregate consumption and expenditure, as each level has distinct important features. JEL Classification: D12, Q41, R21

Development of Oil Industry in Poland in the Context of the European Union.

Oil industry is developing well in Poland. This study aimed to examine the development of the Polish oil industry after joining the European Union. The following questions were asked: What were the changes in the consumption of vegetable oils in Poland after EU enlargement in 2004? How did the production of vegetable oil change in Poland after EU enlargement in 2004? And has the liquidity of the Polish oil industry changed after EU enlargement in 2004? First, the changes in the oil industry were evaluated. This research proved the development of the fat industry. We used the regression model to analyze the impact of chosen factors on the economic situation of the oil industry in Poland. Rapeseed is the main source of oil for the edible oil and biodiesel industry. High prices of rapeseed increased the sown area of rapeseed. The production of crude rapeseed oil changed from 520.1 thousand tons in 2005 to 1440 thousand tons in 2023. Biofuels made from rapeseed oils are called first generation. Poland's production of refined rapeseed oil changed from 386.5 thousand tons in 2005 to 541 thousand tons in 2023. These numbers confirm the development of edible oil and biofuel production. The gross profit increased from PLN 133 mln in 2005 to PLN 443.8 mln in 2023. The net profit of the fat industry increased from PLN 110 mln in 2005 to PLN 381.6 mln in 2023. The oil industry is characterized by high investment, which reached the level of PLN 232.9 mln in 2023. The investment rate in 2023 was PLN 1.96 %. The changes observed in the rapeseed market after Poland joined the EU affected the performance of vegetable oil and biofuel producers. The regression analysis proved the hypothesis that the monthly consumption of rapeseed oil is the main factor influencing the oil industry situation in Poland. The oil industry is important to the development of the whole economy. Particular attention should be paid to current liquidity, which is why a constant supply of money from sold oil and biodiesel is needed to cover costs.

Holding on until the barrel is empty? Algeria's bumpy trajectory towards a post-rentier state

Rentier states are under increasing pressure to move towards a post-rentier state model as peak oil demand is approaching. However, it remains unclear if or how a rentier state can make this transition. To answer this, I developed an analytical framework including the mechanisms from the rentier state theory that need to be present to move towards a post-rentier state. This analytical framework is hypothetical, as up to now, no rentier state has been able to transition to a post-rentier state. Using Algeria as a case study, this novel framework is used to analyse the incremental evolution Algeria has made towards a post-rentier state since the year 2000. I argue that Algeria experienced several internal as well as external opportunities and threats and was influenced by its history on how it responded. Although Algeria fulfilled several steps of the framework, it failed to fulfil necessary sustainability aspects to become a post-rentier state.

Protective Effect of Extra Virgin Olive Oil on Cancers, Gastrointestinal Cancers, and All-Cause Mortality: A Competing Risk Analysis in a Southern Italian Cohort.

This study investigates the association between extra virgin olive oil (EVOO) consumption and mortality risk in a cohort of Italian adults adhering to the Mediterranean diet. In a 17-year follow-up study involving participants from Castellana Grotte, Italy (2005-2023), we analyzed dietary intake and mortality data. Participants were categorized into three EVOO consumption groups: <30 g/day, 30-50 g/day, and >50 g/day. Mortality Hazard Ratios (HR) and Subdistribution Hazard Ratios (SHR) were calculated to assess the relationship between EVOO intake and all-cause and cancer mortality. Higher EVOO consumption was associated with significantly reduced cancer and all-cause mortality. Specifically, the daily intake of 30-50 g of EVOO was linked to a 24% lower risk of all-cause mortality (HR 0.77; 95% CI 0.63-0.93), while the consumption of more than 50 g/day was associated with a 20% reduction (HR 0.80; 95% CI 0.65-0.98). The most pronounced benefit was observed for gastrointestinal cancers, with a 60% lower mortality risk for those consuming over 50 g/day (SHR 0.39; 95% CI 0.21-0.73). A 50% reduction in mortality risk from other cancers was also noted for the highest consumption category (SHR 0.50; 95% CI 0.31-0.81). The findings support the beneficial role of EVOO in reducing cancer mortality, particularly with higher consumption levels. The results underscore EVOO's potential as a dietary intervention for cancer prevention, aligning with the Mediterranean diet's overall health benefits. Further research is needed to confirm these findings and explore the underlying mechanisms.

Predicting China’s Energy Consumption and CO2 Emissions by Employing a Novel Grey Model

The accurate prediction of China’s energy consumption and CO2 emissions is important for the formulation of energy and environmental policies and achieving carbon neutrality. This paper proposes a new weighted error evaluation criterion that emphasizes the importance of new data, thereby enabling more accurate capture of the variation characteristics of new data and reflecting the principle of new information priority. By optimizing the development coefficient, grey action, and parameters in the time response formula of the traditional GM(1,1), a novel optimized model, OGMW(1,1), is constructed. The accuracy of the new model is verified by three cases from the literature. The future trends of primary energy, oil, and coal consumption and CO2 emissions in China are predicted over the next five years. The conclusions are as follows: First, the new weighted error evaluation criteria are effective and reasonable and can indicate whether a grey model can reliably use the most recent information for modeling. Second, based on the new error evaluation criteria, the development coefficient, ash action, and parameter C in the time response function can be optimized. The results show that the optimization method is reasonable. Third, compared with the traditional models GM, GMO, and ARIMA, the OGMW(1,1) provides better simulation and prediction accuracy, and new information can be prioritized more effectively. Fourth, the forecasting results indicate that China will increase its consumption of primary energy, oil, and coal, as well as its CO2 emissions. Notably, the growth rates of primary energy and oil consumption are high at approximately 22.7% and 25%, coal consumption will increase slightly, and CO2 emissions will increase by approximately 11%.

A review of environmental and health effects of synthetic cosmetics

The use of cosmetic products is expanding globally, and with it, so is the range of chemical substances employed in their production. As a result, there is also a higher risk of intoxication, allergic reactions, prolonged chemical exposure, adverse effects, and indiscriminate use. Cosmetic products can contain more than 10,000 ingredients. Most users of synthetic cosmetics are unaware of the harmful effects if they even are. However, it is linked to many diseases like cancer, congenital disabilities, reproductive impairments, developmental systems, contact dermatitis, hair loss, lung damage, old age, skin diseases and reactions, allergies, and harm to human nails. Many beauty products also create a high demand for natural oils, leading to extensive and intensive cultivation, harming natural habitats through deforestation, and contaminating soil and water through pesticides and fertilizers. The adverse effects of hazardous substances in synthetic cosmetics extend beyond human health and influence ecosystems, air quality, and oceans. Thus, this review aims to assess the environmental and health impacts of cosmetics using published scientific articles. The study used a systematic review based on Scopus, Science Direct, Web databases, Scholar Google, and PubMed. The results of this review showed that the formulation of cosmetics until the disposal of their containers could adversely affect environmental and human health.

Analysis of Impact of Control Strategies on Integrated Electric Propulsion System Performance During Icebreaking Process

Developing an efficient power system is an important way for icebreakers to respond to high maneuverability and strong fluctuation loads under icebreaking conditions. The performance of power systems under short-period, regularly fluctuating load-sea conditions has been intensively studied. However, the performance of the power system in the face of a long-period, stochastic multi-frequency fluctuation icebreaking process has not been fully explored, especially the parameter uncertainty and battery cycle life. In this study, an integrated electric propulsion system with an optimal control strategy is suggested for improving the power system’s dynamic performance and battery cycle life. First, an energy flow model with a diesel–electric unit as the main body and coupled energy storage system/hybrid energy storage system has been constructed. A comparative analysis of rule-based and optimization-based energy management strategies has been performed, and an optimized strategy with dynamic programming as global regulation at the upper level and model predictive control at the lower level is suggested to integrate the slow and fast dynamic powers and achieve adaptability to strong fluctuation loads. In this control strategy, the uncertainties of energy storage system/hybrid energy storage system parameters have been introduced to eliminate their impact on the system performance. Then, the icebreaking process with multi-frequency fluctuation has been simulated, and the hybrid energy storage system with battery and supercapacitor is recommended to reach multi-objective with the lowest power fluctuation of diesel–electric unit, highest efficiency, and the minimum battery degradation. Finally, the fuel oil consumption and emissions of the hybrid energy storage system have been discussed, and the optimized strategy can save fuel oil by up to 5.33% and reduce the CO2 emission by 22% during the icebreaking process, exhibiting great potential in the environmental friendliness and significant advantages in terms of low fuel oil consumption.

Effects of frying and food items on the physicochemical properties of palm oil obtained from Nigeria

The consumption of palm oil has particularly increased in Nigeria due to increased population, lifestyle changes, and its health benefits. The conversion and recycling of the ever-growing food waste from household and commercial is one of the known cost-effective and sustainable management strategies. This study investigates the effect of processing on the physicochemical properties of palm oil. Neat palm oil (NPO) and waste palm oil (WPO) samples, derived from frying four different Nigerian food items, were analyzed to determine changes in their physicochemical properties. The outcome of the investigation reveals that higher temperature during frying and contamination from different food items weakens the molecular structure of the palm oil thereby reducing the quality and stability of the samples which is expressed by the differences in their physicochemical properties. The density, peroxide value, and carbon, hydrogen, and oxygen (CHO) values of NPO were 886 kg/m3, 9.473 meqO2/kg, and 39.233% while that of the WPO samples vary between 3.989–4.692 kg/m3, 10.858–15.362 meqO2/kg, and 52.346–58.468%, for density, peroxide value, and CHO, respectively. The result of the descriptive statistics shows that in the 1 series, the mean ± standard deviation (SD) [coefficient of variation (CV%)] is 119.76 ± 263.87 (220.33%). Both the SD and CV% are greater than the mean; this is due to the heterogeneous nature of the parameter values in the samples. When subjected to inferential statistical analysis, the results show that the error of prediction of relationship in NPO sample versus WPO samples is just 5.290% whereas the reduction in the error is 94.71%. More collaborative investigations are needed to determine the ease of conversion to biodiesel and the properties of biodiesel produced from WPO used to fry different Nigerian food items.

Association between fish oil and glucosamine use and mortality in patients diagnosed with cancer: the role of the Life Essential 8 score and cancer prognosis

BackgroundThe effect of supplements on mortality risk in patients with cancer remains uncertain and has scarcely been investigated in subgroups of patients with varying characteristics. This study aimed to investigate the association between two popular supplements, fish oil and glucosamine, and mortality risk in a large population-based cohort and determine whether cardiovascular health and clinical prognosis influence these associations.MethodsThis prospective cohort study analyzed the data of UK Biobank participants who were diagnosed with cancer. The associations of fish oil and glucosamine consumption with mortality were analyzed using Cox proportional hazards models. Subgroup analyses were performed to assess the effects of Life Essential 8 [LE8] scores (a measure of cardiovascular health) and cancer prognosis (grouped according to the survival rates of specific cancer types) on the associations between supplement use and mortality.ResultsThis analysis included 14,920 participants (mean age = 59.9 years; 60.2% female). One third (34.1%) of the participants reported using fish oil, and one fifth (20.5%) reported using glucosamine. Over a median follow-up of 12.0 years, 2,708 all-cause deaths were registered. The use of fish oil was associated with reduced risks of all-cause mortality (adjusted hazard ratio [aHR] = 0.89, 95% Confidence Interval [CI] = 0.81–0.97) and cancer mortality (aHR = 0.89, 95% CI = 0.81–0.98). Similarly, glucosamine use was associated with reduced risks of all-cause mortality (aHR = 0.83, 95% CI = 0.74–0.92) and cancer mortality (aHR = 0.83, 95% CI = 0.74–0.93) in the fully adjusted model. Subgroup analyses revealed that the protective effects of fish oil and glucosamine against mortality risk were only observed in patients with LE8 scores lower than the mean score or a poor cancer prognosis. Additionally, the association between glucosamine use and a reduced risk of CVD-related mortality was only observed in patients with lower LE8 scores.ConclusionsThis large cohort study identified the potential differential impact of LE8 scores and cancer prognosis on the associations of fish oil and glucosamine supplementation with survival in patients with cancer. This suggests the importance of considering these factors in future research on supplements and in the provision of personalized integrative cancer care.

Development of the Separation Column’s Temperature Field Monitoring System

Oil is one of the main resources used by all countries in the world. The ever-growing demand for oil and oil products forces oil companies to increase production and refining. In order to increase net profit, oil producing companies are constantly upgrading equipment, improving oil production technologies, and preparing oil for further processing. When considering the elements of primary oil refining in difficult conditions, such as hard-to-reach or in remote locations, developers face strict limitations in energy resources and dimensions. Therefore, the use of traditional systems causes a number of difficulties, significantly reducing production efficiency. In this study, the authors solve the problem of improving the characteristics of the oil separation process. In their work, the authors analyzed the separation columns of primary oil distillation, identified the shortcomings of the technological process, and searched for technological solutions. Having identified the lack of technical solutions for monitoring the state of the temperature field of the separation column, the authors developed their own hardware–software complex for monitoring the separation column (RF patents No. 2020665473, No. 2021662752 were received). The complex was tested and successfully implemented into production. The study provides an assessment of the economic efficiency of implementation for a year and a forecast of the economic effect for 10 years.
