Swot analysis of utilization of palm oil mill effluent to improve soil quality and crop productivity (case study at PT X, Lampung, Indonesia)

Crude Palm Oil (CPO) manufacturing in palm oil processing plants produces by- products known as palm oil mill effluent (POME). POME can improve the physical and chemical properties of the soil because it contains nutrients N, P, K, Mg, and Ca. One of the companies that have processed and utilized POME is PT X, Lampung Province, Indonesia. This study was conducted to analyze the strengths, weaknesses, opportunities, and threats (SWOT) of the effect of using POME on oil palm plantations for waste quality, physical soil conditions, soil chemical conditions and productivity of oil palm plants. The methodology of the research was using descriptive statistical methods of the secondary data and SWOT analysis. The results showed that the palm oil effluent applied in the PT X complied with the national quality utilization and waste management standards. The POME application has a beneficial effect on soil conditions. The involved area had higher pH, N, P, K, Ca, and Mg than control, but C- Organic and CEC in the application area were lower. Furthermore, the application of palm oil effluent tends to increase crop productivity in a range of 7.57 - 63.23%. The primary strategy obtained from the SWOT analysis is that it is necessary to conduct an intensive assessment and to implement appropriate and proper management and application. This recommended strategy is to get the value of the application of palm oil liquid waste suitable for a long-term sustainable waste application for soil and plants to improve the physical and chemical properties of the soil optimally.

Application of CFD to Improve on Reliability and Efficiency of Centrifugal Pump for Oil and Gas Processing Plant

Centrifugal pump is one of the standard pump specification uses in process industries for qualitative and quantitative fluid transfer. Most industrial application of centrifugal pump has mechanical configuration problems that resulted to pump inefficiency and malfunctions. Fault or bad design pumps are characterized due to quality engineering design which prompted this investigation. In this study, CFD code was used to simulate pump efficiency and compared with real experimental studies. Within the limit of simulation experimental error, it was found that, the centrifugal pump was designed within the constraint of pumping at a flow rate of 0.04 m3/s and at a Head of 55-70 m. After the design calculations, the system was model and drawn in SOLIDWOKS, it was found that the pump was given the required material from the software material library in line with the design specifications and parameters using local materials. The performance of the pump was simulated and evaluated to have a flow rate of 0.043 m3/s, velocity of 8.2 m/s with a head of 70 m and various efficiencies ranging from 68.45 - 81.61%. After the analysis was done, 590 it was identified to be the optimum impeller outlet blade angle in which volumetric efficiency and hydraulic efficiency is maximum. The efficiency pressure ratio has also increased; therefore the pump head also increase. Keywords: Flow, pump, efficiency and reliability

The Impact of Carbon Capture Storage and Utilization on Energy Efficiency, Sustainability, and Production of an Offshore Platform: Thermodynamic and Sensitivity Analyses

Abstract Oil and gas production in FPSOs (floating, production, storage, and offloading) faces a dual challenge: meeting variation in energy demand while decreasing its negative environmental impact. The present article integrates thermodynamic analysis of oil and gas processing plants and screening analysis to determine the most important operational parameters to lower energy demand and increase efficiency and production. Therefore, the main goals of this study are to identify the contribution of the total effect of the operating parameters in an FPSO with CCUS (CO2 capture, utilization, and storage). Twenty-seven thermodynamic and structural design variables are selected as input parameters for the sensitivity analyses. Four machine learning-based screening analysis algorithms such as smooth spline-analysis of variance (SS-ANOVA), PAWN, gradient boosting machine (GBM), and Morris are adapted to achieve the following objectives: (1) overall power consumption of FPSO, (2) CO2 removal efficiency of carbon capture and storage (CCS), (3) power consumption of CCS, and (4) total oil production. The influence of three real crude oil compositions with variations in gas–oil ratio (GOR) and CO2 content is assessed. The combination of thermodynamic and screening analyses showed that the optimal operating pressure parameters of CCS significantly reduce the energy consumption and exergy destruction of the key main and utility plants. Furthermore, the results indicated that total power consumption, CCS efficiency, and CCS power consumption are much more sensitive to the CO2 content of the fluid reservoir than GOR, while the total oil production is influenced only by the GOR content. Finally, for scenarios with high CO2 or GOR content, the effect of design variable interactions is decisive in changing the separation efficiency and/or the compression unit performance.

Shear thinning and shear thickening aspects in magnetized 3D cross-nanofluid flow with activation energy and motile microorganisms

Bioconvection has recently become a point of contention in several biotechnological fields that rely on fluids and their physical properties. Bioconvection tends to happen when mixed nanofluids are subjected to elevated and mass transmission. I'm fascinated by the widespread use of bioconvective nanofluids in the construction of microbial fuel cells, microbial oil extraction mechanisms, processing plants, and other applications. Current research looks at the heat and mass transport properties of cross-nanofluid. Effects of stratification for double diffusion are also considered. Variable thickness sheets are increasingly being used in civil engineering, mechanical, aeronautical, and maritime processes and constructions. Flow and heat transfer across stretching surfaces is used in many technical processes, including polymer extrusion, plastic film stretching, food, and paper processing, fiberglass manufacturing, wire drawing, and continuous casting. Primary goal of the ongoing research is to learn about the properties of activation energy, nonlinear thermal radiation, heat sink source, and motile microorganisms of three-dimensional cross nanofluid flow. The bvp4c structure is used to numerically encode the boundary value problem in the MATLAB mathematical code. To retrieve numerical and graphical reports on velocity, thermal, and energy profiles versus the values of the most important physical parameters, graphs and tables were used.

VOCs and Odor Episodes near the German-Czech Border: Social Participation, Chemical Analyses and Health Risk Assessment.

People living on both sides of the German–Czech border are subject to episodes of odor air pollution. A joint German–Czech air sampling and risk assessment project was established to identify the substances responsible and their sources. Twenty-four volunteer study participants, 14 from the NW Czech Republic and 10 from Germany (Saxony) reported odors and collected canister samples during sampling periods in winter 2017 and 2018 and autumn 2018. Canister samples and passive samplers were analyzed for volatile organic compounds (VOCs) and passive samplers were analyzed for VOCs and carbonyls. OAVs (Odor Activity Values) and back trajectories were calculated with the aim of identifying the odor sources. Calculated OAVs were in excellent agreement with perceived smells close to an oil processing plant. Odorants identified in fifty canister samples during odor episodes and carbonyl measurements close to the edible oil processing plant were used for health evaluation. Odors reported by participants in Saxony frequently differed from those reported by participants in the Czech Republic. This suggests that certain sources of odor lying on either side of the border only affect that side and not the other with similar considerations regarding health effects. VOCs, including carbonyls, were also sampled at two relatively remote locations during winters of 2017 and 2018; two main sources of odorous compounds were identified at these sites. Analysis of samples taken at sampling sites shows that VOC air pollution and, to a lesser extent carbonyl pollution, originate from both industrial and local sources. Even though levels of sampled substances were not associated with acute effects at any site, long-term exposures to selected compounds could be cause for concern for carcinogenicity at some sites. Odors in Seiffen were associated with carcinogenic compounds in can samples. Although not necessarily representative of long-term exposures to the compounds studied, results such as these suggest that further study is needed to better quantify long-term exposure to potentially harmful compounds, and to either confirm or deny the existence of substantive health risk.

АНАЛИЗ ДЕФОРМАЦИЙ И НАПРЯЖЕНИЙ ОБОЛОЧКИ ВЕРТИКАЛЬНЫХ СТАЛЬНЫХ РЕЗЕРВУАРОВ ПО ДАННЫМ ЛАЗЕРНОГО СКАНИРОВАНИЯ

The article considers a new technology of measurements of vertical steel tanks (ground-based laser scanning), which delivers a huge volume of unstructured information. There has been carried out a review of existing methods for solving tasks of tank walls' defomations determinations on laser reflec-tion point cloud. It is noted that the accuracy of laser scanning and scans' stitching is sufficient for tank walls' defomations determinations. The existing methods are implemented basically through building irregular triangular surfaces of tank shell on which then surface profiles are built manually or semi-automatically and the defomations are determined and compared to tolerance values. The au-thors suggest a method and algorithm for processing laser reflection point cloud, which by means of several infiltrations by height, radius tolerance and inclinations and interpolation by collocation meth-od is drawn to a rectangular topologically equivalent grid. These allow by several orders to decrease the information volume stored in the database, and regular grid model structure allows to apply numer-ical calculation method for calculating strains occurring in the tank walls. The strains are determined on semi-momentless theory for cylinder shell calculation. The method and algorithm are implemented in geodetic subsystem of automatic system of technical maintenance and repairs of equipment on the oil processing plant. The suggested method will allow in the future to move from normative assess-ment of technical tank state to the assessment on actual strains, which gives objective assessment of tank state for making substantiated decision on the prolongation of its exploitation, current mainte-nance and repair.

Advanced Exergy Analysis of the Oil and Gas Processing Plant on an Offshore Platform: A Thermodynamic Cycle Approach

Державне регулювання та підтримка виробництва синтетичного рідкого палива в Україні

The article proves that today motor fuels is an important component of both energy and national security of any country in the world, since it provides transport and equipment with the necessary energy resource. After the invasion of the territory of Ukraine by the armed forces of the russian federation and the destruction caused by shelling and hostilities of a number of oil and gas processing plants, it is necessary to restore or create a new production of motor fuels on the country’s own raw material base as soon as possible. The only energy resource that can partially meet Ukraine’s needs for motor fuels through the country’s own production is coal and lignite. The establishment of the production of synthetic liquid fuels (SLF) from coal and lignite in the regions of Ukraine will help strengthen the country’s energy security, and national security in particular. At the same time, the creation and development of SLF production requires proper government support and regulation. The aim of the study is to determine the features and directions of improving government regulation and supporting the production of SLF in Ukraine. Based on the carried out study, it is proved that the lack of both production and market of synthetic analogues and components of liquid motor fuels in Ukraine determines that the regulatory field of enterprises for the production of SLF is represented by the current regulatory framework for economic relations in the sphere of oil and oil products turnover. Therefore, it is highly likely that the development of SLF production in Ukraine will take place in the regulatory field, which does not take into account the specifics of new industries. This inconsistency can create undesirable additional barriers to their entry into the national market of petroleum products. It is recommended to allocate synthetic analogues of motor fuels into a separate commodity group, for which it is advisable to establish a special excise tax rate and other preferences that can provide sufficient investment flow for the creation of SLF production facilities.

Аналіз сировинного потенціалу виробництва моторного палива в Україні та її регіонах

Motor fuel is an important component of both energy and national security of any country in the world, as it provides civilian transport and military equipment with the necessary energy resource. After the invasion of the armed forces of the russian federation on the territory of Ukraine and the destruction resulted from shelling of a number of oil and gas processing plants in the country, a difficult situation has developed that requires either an urgent restoration or creation of a new production of motor fuel on the country’s own raw material base. The aim of the study is to determine the current status of the raw-materials potential for the production of motor fuel in Ukraine and its regions. To achieve this goal the authors have: considered the combustible minerals of the country; analyzed the distribution of reserves and production of natural gas, oil, coal, and peat; examined the structure of distribution of their balance extractive reserves by regions of Ukraine, and the dynamics of production; computed the total energy potential of combustible minerals of Ukraine; identified sources of renewable resources that can be used for energy production; determined that the first-generation liquid biofuels include bioethanol and biodiesel; calculated the current technical potential of bioethanol production from corn and rapeseed by regions of Ukraine; identified the leading regions in terms of the potential for the production of liquid biofuels in Ukraine; formed the structure of energy potential by types of combustible minerals and biofuels in the country; determined the total energy potential of combustible minerals of Ukraine and formed the structure of the total energy potential of combustible minerals and biofuels in the regions of the country

ТРАНСПОРТНАЯ СЕТЬ РЕСПУБЛИКИ БАШКОРТОСТАН КАК ОСНОВА ДЛЯ СОЗДАНИЯ КАРБОНОВЫХ ПОЛИГОНОВ С ЦЕЛЬЮ ПРОИЗВОДСТВА ИСКУССТВЕННЫХ УГЛЕВОДОРОДОВ

This study presents the prerequisites for the development of artificial hydrocarbons on the territory of the Republic of Bashkortostan. The reduction of proven oil reserves, the high cost of hydrocarbons in the market, as well as climate change contribute to the development of renewable energy sources. Thus, in the world, biodiesel production in the United States occupies a leading position after Europe. However, insufficient attention is paid to this production in the Russian Federation. The polarization of petrochemical and oil refining enterprises, especially the fuel sector, may face a short supply of traditional hydrocarbon raw materials – oil in the future, which may lead to a socio-economic decline in the life of the population of this territory. Such territories of the Russian Federation include the Republic of Bashkortostan. At the same time, a developed logistics transport network can contribute to the development of renewable energy sources, which contributes not only to the continuation of the life cycle of petrochemical and oil refining enterprises, but also to the activation of regions' economic growth points. The article provides a detailed analysis of motor transport and railway routes in the region, which shows that the uniformity of the growth of socio-economic development directly depends on the infrastructure, primarily cargo transportation along transport routes. In the article, the author suggests that for the rapid socio-economic development of the territory of the Republic of Bashkortostan, it is necessary to fully use not only roads and railways, but also the water transport system of the region. So, if examples of creating experimental polygons for the production of artificial hydrocarbons in Buraevsky, Mishkinsky, Baltachevsky, Tatyshlinsky, Yanaulsky, Kaltasinsky regions of the Republic of Bashkortostan were chosen, then the river route can be considered as an effective way for transporting finished products. In addition, in the Askinsky district of the republic, the operation of the oil processing plant of the Oleokemix company was successfully introduced, the goal of which is to become a leader in the republic in terms of crops, a high degree of sharpness of rapeseed oil in Russia. Therefore, the development of a transport network, experimental sites for the production of artificial hydrocarbons in the northwestern direction of the Republic of Bashkortostan, intensive development of industrial energy sources, including biofuels.

The calculation of required fire resistance limits for engineering structures of technological pipe racks at oil and gas processing plants on the basis of an evaluation of the time needed for personnel evacuation and rescue in case of fire

Introduction. GOST R 12.3.047-2012 standard offers a methodology for determination of required fire resistance limits of engineering structures. This methodology is based on a comparison of values of the fire resistance limit and the equivalent fire duration. However, in practice incidents occur when, in absence of regulatory fire resistance requirements, a facility owner, who has relaxed the fire resistance requirements prescribed by GOST R 12.3.047–2012, is ready to accept its potential loss in fire for economic reasons. In this case, one can apply the probability of safe evacuation and rescue to compare distributions of fire resistance limits, on the one hand, and evacuation and rescue time, on the other hand.A methodology for the identification of required fire resistance limits. The probabilistic method for the identification of required fire resistance limits, published in work [1], was tested in this study. This method differs from the one specified in GOST R 12.3.047-2012. The method is based on a comparison of distributions of such random values, as the estimated time of evacuation or rescue in case of fire at a production facility and fire resistance limits for engineering structures.Calculations of required fire resistance limits. This article presents a case of application of the proposed method to the rescue of people using the results of full-scale experiments, involving a real pipe rack at a gas processing plant [2].Conclusions. The required fire resistance limits for pipe rack structures of a gas processing plant were identified. The calculations took account of the time needed to evacuate and rescue the personnel, as well as the pre-set reliability of structures, given that the personnel evacuation and rescue time in case of fire is identified in an experiment.

Production method of reference fluids intended for gravitational settlers' efficiency verification tests

Crude oil generally reaches the platform in a mixture of crude oil and water, among other components. These products flow through valves and pumps, where agitation leads to the occurrence of emulsions. Their presence is undesirable as they lead to an increase in transportation and oil processing costs. Moreover, water content is a factor employed on the benchmark of crude oil prices. Efficiency verification tests for oil processing plants equipment, such as gravity settlers, usually occur with the use of crude oil emulsions obtained in the field. However, such emulsions are fluids that may exhibit toxic, volatile, and flammable behaviors. In this research, we develop a general method for the synthesis of reference fluids intended for replacing crude oil emulsions in gravitational settlers' efficiency verification tests. This method comprises an extensive procedure for mimicking crude systems and their behavior on gravitational settlers. This is achieved by defining key parameters, characterizing some crude systems in relation to these properties and pursuing reference systems with similar characteristic values through an iterative process. A comprehensive theoretical analysis supporting the procedure is also presented. We have also developed two case studies in which materials, experimental protocols, and emulsification techniques that could be employed are described. Furthermore, the reference fluids obtained in these case studies are benchmarked in relation to their crude systems counterparts. In general, our reference fluid for A-crude systems presented valuable results.

Agricultural waste management generated by agro-based industries using biotechnology tools

The amount of agricultural waste generated by agro-based industries such as palm oil, rubber, and wood processing plants have more than tripled. Selangor, Perak, and Johor account for 65.7 percent of the total number of recognised pollution sources in the manufacturing and agro-based sectors. Livestock dung is another major cause of pollution, contributing significantly to increase pollution levels in the environment. Large portion of agro-industrial waste is untreated and unused, it is frequently disposed of by replicating or dumping then again off the cuff landfilling. These untreated wastes wreak havoc on natural change by releasing ozone-depleting chemicals. Aside from that, the usage of fossil fuels is also leading to an increase in ozone-depleting compounds. Agro-waste is a huge environmental hazard in the current epidemic situation. The management of agro-waste and the conversion of agro-waste into a usable product through the application of biotechnological technologies in agriculture are receiving a lot of attention in today''s world. Solid state fermentation is the finest approach for converting agro-waste into valuable bio products among biotechnological instruments. Various agro-wastes such as wheat straw, barley straw, cotton stalks, sunflower stacks, and oil cakes from various agriculture goods, as well as major horticulture wastes such as apple, mango, orange peels, and potato peels, were used to create beneficial products in this review. All aspects of the production of industrial products from various agro-waste by using microorganisms such as Amycolatopsis Mediterranean, Xanthomonas campestries, and Aspergillus niger producing biopolymers such as polysaccharides, similar to starch, cellulose, agar, hemi-celluloses, gelatin, alginate, and carrageenan are covered in the current revels. Yeasts and cyanobacteria are commonly employed to make bio-lipids, whereas Bacillus species are utilised to make proteins and bio-enzymes. Cucumber and orange strips, on the other hand, have recently been employed to create proteins and bio-enzymes. As a result, this review covers the many forms of agro-wastes and their by-products as well as biotechnological technologies used to treat them.

Base Oil Process Modelling Using Machine Learning

The quality of feedstock used in base oil processing depends on the source of the crude oil. Moreover, the refinery is fed with various blends of crude oil to meet the demand of the refining products. These circumstances have caused changes of quality of the feedstock for the base oil production. Often the feedstock properties deviate from the original properties measured during the process design phase. To recalculate and remodel using first principal approaches requires significant costs due to the detailed material characterizations and several pilot-plant runs requirements. To perform all material characterization and pilot plant runs every time the refinery receives a different blend of crude oil will simply multiply the costs. Due to economic reasons, only selected lab characterizations are performed, and the base oil processing plant is operated reactively based on the feedback of the lab analysis of the base oil product. However, this reactive method leads to loss in production for several hours because of the residence time as well as time required to perform the lab analysis. Hence in this paper, an alternative method is studied to minimize the production loss by reacting proactively utilizing machine learning algorithms. Support Vector Regression (SVR), Decision Tree Regression (DTR), Random Forest Regression (RFR) and Extreme Gradient Boosting (XGBoost) models are developed and studied using historical data of the plant to predict the base oil product kinematic viscosity and viscosity index based on the feedstock qualities and the process operating conditions. The XGBoost model shows the most optimal and consistent performance during validation and a 6.5 months plant testing period. Subsequent deployment at our plant facility and product recovery analysis have shown that the prediction model has facilitated in reducing the production recovery period during product transition by 40%.

A new method to select demulsifiers and optimize dosage at wet crude oil separation facilities

The current practice for crude oil demulsifier selection consists of pre-screening of the best performing demulsifiers followed by field trials to determine the optimum demulsifier dosage. The method of choice for demulsifier ranking is the bottle test. As there is no standard bottle test method, there are different methodologies reported in the literature. In this work, a new approach to bottle test and field trial was described which improved significantly the selection and dosage of the demulsifier. The bottle test was optimized by measuring an accurate mass of demulsifier. This method produces repeatable results. This bottle-test methodology was benchmarked against field trial results performed in oil processing plants. The field trials were also improved to avoid the accumulation effect of demulsifier, when optimizing their dosage. The field data for the optimization of demulsifier dosage was analyzed mathematically; and a graphical method to determine the optimum range is described.
