The influence of particle size and velocity on the wear failure of TiC coated Fe under oil extraction conditions: A molecular dynamics study

The application of titanium carbide (TiC) coatings, renowned for their exceptional tribological properties, holds promise for the research on failure prevention in downhole petroleum machinery. In this study, molecular dynamics was employed to coat TiC layers onto Fe surfaces to enhance wear resistance. The effects of particle size and velocity on the wear and erosion resistance failure of the entire system were investigated through nanoindentation, scratch tests, and particle impact studies. The results indicate that the influence of particle size on the abrasion resistance and erosion resistance of materials is manifested in the load trend and surface atomic morphology. In the plastic damage of materials, an increase in velocity weakens the accumulation of slip faults and rearrangement phenomena among internal atoms, resulting in irregular fluctuations in the load curve. Meanwhile, the high-speed system will dominate the influence on temperature by accelerating atomic motion, leading to different orders of magnitude of wear and high-temperature atoms in impact simulations compared to particle size. This provides significant reference for the study of protective failure of TiC coatings in complex oil machinery service environments.

Neutrosophic analysis of avocado oil extraction conditions by varieties

Avocado oil is defined by the composition of the fruit and its nutritional value, which according to previous studies suggests that it provides health benefits, reduces cardiovascular disease, and provides anti-inflammatory and antioxidant effects. However, the nutritional value is determined by the amount of acid. Monounsaturated and polyunsaturated fatty acids make this product useful in cooking. The quality of the oil is affected by the method and conditions of extraction, as these processes affect the preservation of nutrients and beneficial properties of avocado oil. This study aimed to conduct a Neutrosophic analysis of avocado oil extraction conditions depending on the cultivar, dehydration and cold pressing conditions. As a result, the physicochemical properties of the reaction variables were determined and the values of acidity, moisture, density, and impurities were obtained for the oil obtained from the Hass variety by dehydration and pressing.

Formulation of Neem Leaf and Croton Seed Essential Oils as a Natural Insecticide Tested on Mosquitoes and Cockroaches.

Essential oils are highly aromatic plant oils utilized as a new insect control alternative to synthetic insecticides because of environmental concerns. As a result, the purpose of this study was to evaluate the effects of essential oil extraction conditions on neem leaf and cotton seed, as well as to identify their chemical composition using gas chromatography-mass spectrometry. Moreover, both extracted oils were subjected to bioinsecticide formulation in individual as well as mixed forms, which were tested on mosquitoes and cockroaches using the conventional roach killer and a blank control as a comparison. The results revealed that the maximum yields of essential oils from neem leaf and croton seed were respectively 30.54 and 14.75%. The extraction process was greatly affected by the particle sizes because of the mass transfer limitation between solute-solvent interactions. The insecticidal evaluation showed that the blended form of essential oils at the 20% concentration has better efficiency than the individual oils, which accounted for 80% mosquito and 71.8% cockroach death rates within 4 h, whereas the synthetic roach killer completely killed all of the insects within the same time frame. Terpineol, α-terpinyl acetate, eucalyptol, and δ-cadinene are the active insecticidal compounds in neem leaf oil, whereas the active compounds of croton seed oil are epiglobulol, copaene, δ-cadinene, α-cubebene, and β-guaiene.

Greener extraction of polycyclic aromatic hydrocarbons from soil and sediment using eucalyptus oil

Polycyclic aromatic hydrocarbons are toxic pollutants which persist in the environment. Extraction of polycyclic aromatic hydrocarbons requires large volumes of toxic organic solvents, but the use of non-hazardous solvents provides a potentially cleaner approach to quantifying polycyclic aromatic hydrocarbons in environmental matrices. Here we investigated the efficiency of eucalyptus oil to extract polycyclic aromatic hydrocarbons from spiked soil and sediment. Eucalyptus oil extraction conditions including temperature, time, and volume of oil were optimized employing a Box–Behnken experimental design, and the desorption kinetics of phenanthrene, pyrene, chrysene, and benzo[a]pyrene were evaluated using an empirical first order kinetic model. Results show that extraction efficiency from soil, of 112% for phenanthrene, 108% for pyrene, 102% for chrysene and 98% for benzo[a]pyrene, is higher than that from sediment, of 90, 111, 84 and 82%, respectively. This may be due to soil possessing 12 times more organic carbon. Recoveries higher than 77% were obtained over the concentration range 0.5–10 mg/kg for the tested polycyclic aromatic hydrocarbons, with limits of detection lower than 63 µg/kg and limits of quantitation lower than 125 µg/kg. These findings suggest that eucalyptus oil has potential as a safer solvent to extract hydrophobic contaminants.

Determination of rational conditions for oil extraction from oil hydration waste

As a result of oil hydration, waste is formed – phosphatide concentrate, which is a multicomponent system. Valuable components of the concentrate are vegetable oil and phosphatides, the separation of which is an urgent task for the industry. The process of treatment of sunflower phosphatide concentrate with citric acid (hydration) in order to more completely convert non-hydrated forms of phosphatides into hydrated ones and separate the oil from the concentrate was studied. A feature of the work is the study of the dependence of the yield and mass fraction of moisture in the extracted oil on the hydration process parameters. A sample of phosphatide concentrate with non-standard quality indicators according to SOU 15.4-37-212:2004 (CAS 3436-44-0) was studied: the mass fraction of moisture and volatile substances was 4.0 %, the mass fraction of phosphatides was 37.0 %. The concentrate was treated with citric acid solution at a temperature of 45 °C (10 % solution). Rational conditions for concentrate treatment were determined: duration (25 min) and citric acid concentration in relation to the mass of phosphatide concentrate (25 %). Under these conditions, the oil yield was 76.1 %, the mass fraction of moisture in the oil was 18.6 %. The indicators characterizing the suitability of the oil for consumption and its safety for the body are within the limits (acid value 3.7 mg KOH/g, peroxide value 5.1 ½ O mmol/kg) for the first-grade unrefined unwinterized sunflower oil according to DSTU 4492. Such oil can be used for refining, fatty acids and biodiesel production, and after additional purification – for processing into food products. The results of the study make it possible to use resources rationally and predict the yield and quality of the oil isolated from the phosphatide concentrate. The resulting oil can be an affordable raw material for various industries.

Study of corrosion resistance of pump-compressor pipes made of ferrite-pearlite steel under the action of carbon dioxide mediums

To ensure required complex of steel strength properties, pipes heat treatment is widely used as a quenching for martensite followed by tempering. It is accepted, that metal microstructure formed at that, has a little effect on a steel corrosion resistance in carbon dioxide mediums. Studies were accomplished of steel microstructure effect of the carbon dioxide corrosion speed. In particular, a low-alloyed structural steel, used for production of oil field pipes was selected. As the object of the study, seamless pumpcompressor pipes (PCP), made of medium-carbon steels of several grades with chrome content about 1% (mass.), subjected to two methods of heat treatment: quenching with tempering or normalization with tempering. Corrosion resistance of the steels were accomplished under laboratory conditions of JSC “RusNITI” by application of autoclave facility imitating operation conditions parameters of a working medium at oil extraction. The speed of general metal corrosion was measured as samples mass loss during tests (from 360 to 70 hours) by gravimetric method. By the results of laboratory tests the steel 35ХГФА was recommended to the industrial production of PCP of K72 and N80 strength groups due to GOST 31446 with normalization and tempering. It was established that pipes of steel 35ХГФА with ferrite-pearlite microstructure have higher corrosion resistance in mineralized water mediums at carbon dioxide partial pressure up to 0.20 atm, comparing with regular pipes, manufactured with quenching and tempering. A complex of field tests of PCP was carried out, the pipes made of experimental steel 35ХГФА at an oil deposit. The result of operation of CPC of 88.9×6.45 mm made of steel 35ХГФА having K72 group of strength (after normalization with tempering) during 550 days under conditions of high-mineralized water phase at СО2 partial pressure up to 0.27 atm was found positive. After an intermediate inspection (550 days) the column of PCP was assembled and is in operation at present, the current running time exceeding 1000 days. Based on the results of the complex comparative tests carried out in the corrosion laboratory and under field oil extraction conditions it was established that usage of experimental steel 35ХГФА containing 1% of Cr, after application of normalization technology with tempering resulted in increasing of operating reliability of CPC.

The present work deals with the production of biodiesel from Sandbox (Hura crepitans) seed oil and the optimization of the parameters that influence the transesterification of Sandbox (Hura crepitans)seed oil into biodiesel using Response Surface Methodology. Hura crepitans oil was obtained from by using hydraulic press for Mechanical and n-hexane for solvent extraction. Esterification was done using methanol and sodium hydroxide. A total of 48 experiments using Central Composite Design were carried out. The R-Squared, Adequate Precision, Predicted and Adjusted R-Squared values were 0.9367, 19.219, 0.8576 and 0.9070 respectively. The result of the extraction of oil, physiochemical properties, and optimization process shows that sandbox (Hura crepitans) seed oil has characteristics that are more favorable to biodiesel production. The optimal conditions for extraction of oil from sandbox seed oil were given as alcohol/ oil ratio of 5.0, catalyst amount of 20 g/ml, extraction temperature of 60 ºC, and extraction time of 45.01 minutes, with the predicted oil yield as 97.33% respectively which shows that the experimental values are in good agreement with predicted values.

Optimization of the eco-friendly solvent-free microwave extraction of Limnophila aromatica essential oil

Seasonal variation can alter the profile, quantity, and bioactivity of secondary metabolites in aromatic plants. This study aimed to establish solvent-free microwave extraction (SFME) conditions for the recovery of essential oil from Limnophila aromatica (Lam.) Merr. aerial parts and investigate the influence of seasonality on this oil. The effects of key SFME variables, including the microwave power and irradiation time, on the essential oil yield were evaluated, and these variables were optimized using response surface methodology. The chemical composition and antioxidant and antiproliferative capabilities of the essential oils obtained under the selected SFME conditions during different seasons of the year were then analyzed. The optimal SFME process conditions for achieving the maximal essential oil yield were 700 W for 25 min. The most important variable influencing oil recovery was the irradiation time (p < 0.001), followed by the microwave power (p < 0.01). The applied extraction method offered essential oil yields during the different seasons ranging from 0.20 % to 0.24 % (v/w). The obtained essential oils showed the presence of forty-seven constituents, mainly limonene, perillaldehyde, (E)-4-caranone, (Z)-4-caranone, and α-pinene. Monoterpene hydrocarbons were the dominant class of compounds in the oils. Seasonality affected both the antioxidant and antiproliferative properties to different degrees. These findings are not only useful for identifying eco-friendly essential oil extraction conditions but also serve as a useful guide for informing agronomic practices during the planting and cultivation of the studied medicinal plant.

Optimization of Progressive Freezing for Residual Oil Recovery from a Palm Oil-Water Mixture (POME Model).

Oil and grease remain the dominant contaminants in the palm oil mill effluent (POME) despite the conventional treatment of POME. The removal of residual oil from palm oil–water mixture (POME model) using the progressive freezing process was investigated. An optimization technique called response surface methodology (RSM) with the design of rotatable central composite design was applied to figure out the optimum experimental variables generated by Design–Expert software (version 6.0.4. Stat-Ease, trial version). Besides, RSM also helps to investigate the interactive effects among the independent variables compared to one factor at a time. The variables involved are coolant temperature, XA (4–12 °C), freezing time, XB (20–60 min), and circulation flow, XC (200–600 rpm). The statistical analysis showed that a two-factor interaction model was developed using the obtained experimental data with a coefficient of determination (R2) value of 0.9582. From the RSM-generated model, the optimum conditions for extraction of oil from the POME model were a coolant temperature of 6 °C in 50 min freezing time with a circulation flowrate of 500 rpm. The validation of the model showed that the predicted oil yield and experimental oil yield were 92.56 and 93.20%, respectively.

Effect of Oil Extraction Conditions on the Anaerobic Fermentation of &amp;lt;i&amp;gt;Jatropha curcas&amp;lt;/i&amp;gt; Seed Cakes

The production of biogas is a heathy way to convert biomass like seed cakes into energy. But before that, oil seeds like jatropha curcas are treated in some conditions in other to get oil first, and cakes after. And different levels of those conditions that are seed type, preheat temperature and extraction pressure can give different results on biogas production using those cakes. That is why in this study, biogas characteristics of cake, from three types of jatropha seeds (whole, kernels and crushed) preheated at four levels of temperature (25°C, 50°C, 75°C and 100°C) and submitted at three extraction pressures (181.81 bar, 324.66 bar and 422.06 bar), were assessed. It consisted in mixing 5 ml solid mixture (2.5 ml of cake sample and 2,5 ml cow dung) to the buffer solution (NH₄Cl, 100; NaCl, 10; MgCl 2 • 6H₂O, 10; CaCl₂.2H₂O, 5) at 1:1 ratio. The mixture was introduced in a reactor of 16 ml volume and then incubated in an electric oven at 37°C for 60 days. The measure of gas volume of each sample was done using the adapted method of displaced liquid. The gas calorific value estimation of each sample was theoretically done, using Buswell equation. And, the gas energy was obtained for each sample, using its gas volume and calorific value. The main results were as follows. The highest volume of biogas (8 ml / g) and highest energy (2485.85 J) were registered with whole seed cake at preheated temperature/extraction pressure couple of 100°C-324.66 bar. The highest calorific value (701.43 KJ/mol) was obtained with the whole seed cake at preheated temperature/extraction/ pressure couple of 100°C-422.06 bars. The main conclusion that can be made is that, there is an effect of oil extraction conditions on the anaerobic fermentation of jatropha curcas seed cakes.

The objectives of this research were to study the optimum condition for extracting oil from carrot peels using supercritical carbon dioxide and find a mathematical equation to predict the percentage of oil yield, oil extraction efficiency, and beta-carotene content. Central composite design was performed for 2 factors, temperature (32, 39, 56, 73, and 80 °C) and pressure (14.2, 16.5, 22.1, 27.7, and 30.0 MPa), to determine the optimum oil extraction conditions based on the highest value of oil yield, extraction efficiency, and beta-carotene content. It was found that the optimum condition was at 80 °C and 14.2 MPa and when comparing the oil yield, oil extraction efficiency, and beta-carotene content obtained from the experiment at the optimum condition to the values obtained from the prediction with the mathematical model, it was found that the deviation values (%D) were less than 10 percent, indicating that the obtained mathematical model can predict the percentage of oil yield, extraction efficiency, and beta-carotene content well. In addition, it was found that the oil from the carrot peels obtained from the experiment was orange with L* a* b* C* and h* at 33.35 26.08 42.28 48.53 and 57.99°, respectively, beta-carotene content iodine value and oil acidity value at 0.27 mg/100mg db, 116.75 mg iodine/100 g oil, 2.43 mg KOH/g oil, respectively and antioxidant properties based on the ferric-reducing antioxidant power assay at 529.08 µMFe2+/g.

Extraction, characterization and optimization of high quality bio-oil derived from waste date seeds

Extraction of high quality bio-oil from waste date seeds would convert these waste seeds to valuable product as well as avoid the hazardous effects associated with date seeds landfilling. The present work provides a systematic study on extracting date seed bio-oil and optimizing the conditions for oil extraction. Effect of various extraction parameters such as grain size, drying method, solvent type and feed to solvent ratio was studied on the oil yield obtained from Sukkary type waste date seeds. N-hexane and chloroform were found to be the most effective solvents for oil extraction and the feed grain size of <200 microns gave the highest oil yield for all methods of drying. For fixed feed to solvent ratio, oven drying at 70 °C produced better oil yield of 9.11% as compared with other drying methods. For feed to solvent ratio, the 1:40 loading recorded a better yield of 8.54% as compared to 7.84% yield obtained for 1:20 loading. Qualitative analysis of as-produced bio-oil using FTIR showed the standard equivalence of date seed bio-oil to that of food grade olive oil. Fatty acid compositions of the date seed derived bio-oil were determined through GC-FID analysis and the results showed commendable bio-oil quality compared to reports of other works.

Optimisation, experimental validation and thermodynamic study of the sequential oil extraction and biodiesel production processes from seeds of Sterculia foetida.

Non-edible seeds are not used in any commercial applications, which implies that they can be used for biofuel applications. The present study aimed to maximise the process conditions for oil extraction and sterculia biodiesel production from Sterculia foetida (poon oil). GC-MS identified the methyl esters of sterculia oil as sterculic acid (32%), palmitic acid (15.88%), oleic acid (10.00%), linoleic acid (9.95%) and malvalic acid (9%). Response surface methodology (RSM) based parametric optimisation of oil extraction was carried out by choosing process variables such as sample weight, volume of solvent to seed ratio and time. The optimum sample amount of 7.5 g and the volume of solvent to seed ratio of 40 mL/g resulted in a maximum oil yield of 45.27% at 3 h. The results were statistically significant (P < 0.05) with a regression coefficient (R2) of 0.9988. Furthermore, the artificial neural network (ANN) resulted in an R2 value greater than 0.9, which validates the RSM. Conventional optimisation of the temperature (55 °C), feedstock to methanol ratio (1:12), catalyst proportion (1.5%) and transesterification reaction time (60 min) yield 90.87% biodiesel production. The physicochemical characteristics of oil and biodiesel complied with the requirements of the ASTM standards. The rate constant and thermodynamic variables at the optimum temperature (333 K) were calculated from the experimental data. The activation energy (Ea), activation enthalpy in transition state theory (ΔH++), activation entropy in transition state theory (ΔS++) and Gibbs free energy in transition state theory (ΔG++) were 37.91 kJ mol-1, 35.14 kJ mol-1, - 239.58 J mol-1 K-1 and 79.81 kJ mol-1 respectively.

THE EFFECT OF AN INCREASE IN PASTE TEMPERATURE BETWEEN MALAXATION AND CENTRIFUGATION ON OLIVE OIL QUALITY AND YIELD: PRELIMINARY RESULTS

Olive oil extraction conditions are usually a compromise between quality and yield. Enhancing yield decreases quality, and vice versa. We aim to understand if a change in temperature between malaxation and centrifugation can result in a better compromise. Thus, malaxation is carried out at 20°C and oil is extracted at 20°C, 27°C, and 35°C. The results show that a moderate increase in temperature between malaxation and centrifugation (i.e. from 20°C to 27°C) increases both yield and quality of the oil. Conversely, an excessive temperature increase (i.e. from 20°C to 35°C) leads to the production of rancid-related compounds.

Oil extraction from butter fruit (&lt;i&gt;Dacryodes edulis&lt;/i&gt;) seeds and its optimization via response surface and artificial neural network

In this study, oil was extracted from butter fruit ( Dacrydes edulis ). To model and optimize the process conditions of oil extraction, Response Surface Methodology (RSM) and Artificial Neural Network (ANN) were used. Physicochemical analysis of the oil was carried out in order to determine the suitable of oil for industrial applications. Dacryodes edulis seeds were collected from Ikot Abasi Village in Eket Local Government of Akwa Ibom State, Nigeria. The seed was washed with clean water to remove dirt, and open with a sharp stainless knife to remove the seed from the pulp. The seeds were cut into small pieces and sundried for 5 days and were grinded into powder. Oil extraction from the powder seed was carried out using Sohxlet extraction method. The experiment was designed using Box-Behnken Design approach on three levels, three factors which generated 17 experimental runs. Independent factors considered were extraction time (X 1 ), solvent volume (X 2 ) and sample weight (X 3 ). The accuracy of the regression model obtained from the optimization software was determined using the co-efficient of determination (R 2 ). Results showed the highest oil yield of 17.878% (w/w) was obtained at solvent volume of 200 ml, sample weight of 50 g and extraction time of 55 min, respectively. However, response surface methodology predicted an oil yield of 17.826% (w/w), while the artificial neural network predicted 17.875% (w/w) at the same variables condition. The predicted values were validated in triplicate, and an average of 17.46% (w/w) and 17.72% (w/w) were obtained for RSM and ANN, respectively. The predicted values obtained were well within the range predicted. The coefficient of determination, which determines the model accuracy, was obtained to be 0.8454 for RSM and 0.8712 for ANN. Physicochemical analysis of the oil showed the oil is highly unsaturated with high saponification value and high iodine value. The study concluded that Dacryodes edulis seeds are found to be rich in oil and the oil can be applicable in industries as raw materials for products formation. Keywords: Dacryodes edulis seeds, response surface, artificial neural network, optimization, extraction, physicochemical properties

Effect of Sunflower Collets Moisture on Extraction Yield and Oil Quality

The aim of this work is to analyze the effect of moisture content of sunflower expanded material on the quality of the extracted oil by determining its wax, phospholipids, and tocopherol content and composition. Sunflower oil extraction is carried out in a batch extractor at 50 °C using hexane and three moisture levels (5.65, 12.40, and 18.92% dry basis). The increasing moisture content causes an increment in both oil yield and total amount of minor compounds. The total wax content ranges between 808 and 1118 ppm, the wax fraction is composed mainly of esters of between 44 and 58 carbon atoms (&gt;67%), and the distribution does not change with the moisture content. In all the experiments, α‐ and β‐tocopherols and β‐tocotrienol are detected, with the level of α‐tocopherol being higher than 93% and easier to extract at 12.40% moisture. Furthermore, the phospholipids content in the oil increases with moisture content but maintains its profile composition. The obtained results can be explained in terms of water activity and the effect of moisture and hexane extraction on solid structure, studied by scanning electron microscopy. In brief, the moisture content of the collets not only affects the oil yield but also the content of minor compounds, the intermediate moisture rendering the better oil yield and quality.Practical Applications: The data obtained provides updated information on oil yield and quality associated with moisture content of sunflower collets, useful to select the optimal operating conditions for oil extraction and to establish a trade‐off between performance and quality.Sunflower collets are conditioned in their moisture content to determine the isotherm sorption and the effects on the oil extraction and quality.

Comparative Chemical Composition and Bioactivity of Opuntia ficus‐indica Sanguigna and Surfarina Seed Oils Obtained by Traditional and Ultrasound‐Assisted Extraction Procedures

This study investigates the seed oils obtained from two different varieties of Opuntia ficus‐indica (Sanguigna and Surfarina) growing in Sicily, Italy. Soxhlet and ultrasound‐assisted extraction procedures are used to obtain the seed oils. The fatty acid profile, γ‐tocopherols, carotenoid content, and the bioactivity in terms of the antioxidant effects (using ABTS, DPPH, FRAP, and β‐carotene bleaching tests), and carbohydrate‐hydrolysing enzyme inhibitory activity (α‐amylase and α‐glucosidase) are determined. The extraction procedure does not significantly affect the fatty acid composition of the oil, but it does affect the tocopherol and carotenoid contents, as well as the antioxidant and inhibitory activities. All the oil samples are rich in polyunsaturated fatty acids, especially linoleic, and oleic acids. Soxhlet extraction proves to be the best extraction procedure to enrich the oils in γ‐tocopherol. Relative antioxidant capacity index (RACI) and global antioxidant score (GAS) analyses are applied to evaluate the antioxidant potential of the Sanguigna variety oil extracted with the Soxhlet apparatus that is shown to be the most active. The same oil also shows the highest α‐amylase inhibitory activity (IC50 value of 40.9 μg mL−1), which is better than that reported for acarbose used as a positive control.Practical Applications: This study is the first to evaluate the effect of oil extraction technologies on the bioactive compound levels and antioxidant and hypoglycaemic activities of cactus pear seed oil, which is a by‐product of fruit processing. The findings will contribute to the valorization of food by‐products. The results provide useful information to select the most valuable technological conditions for oil extraction to preserve the bioactive compounds and the biological activity of the vegetable by‐product extracts, such as seed oil. Cactus pear seed oil obtained by the traditional extraction procedure (Soxhlet) represents a promising source of healthy compounds, particularly of carotenoids and γ‐tocopherol, used not only as antioxidants to preserve lipid components in food preparation but also as functional ingredients due to their hypoglycaemic effect.Effect of extraction procedure on chemical composition, antioxidant potential, and hypoglycaemic activity of cactus pear seed oils.
