Abstract

Coconut oil is a valuable commodity with diverse applications in food, cosmetics, and pharmaceuticals. The extraction process plays a crucial role in determining the quality and yield of coconut oil. Temperature is a critical parameter that affects the efficiency of the extraction process.This study aimed to investigate the effect of temperature on coconut oil extraction using a solvent extraction method, optimizing the extraction process, and providing insights into the relationship between temperature and oil yield. A laboratory-scale solvent extraction method was employed, where coconut oil was extracted from shredded coconut at different temperatures (30°C, 40°C, 50°C, 60°C, and 70°C) using petroleum ether as the solvent. The yield of oil extracted was measured and calculated as a percentage of the initial weight of coconut used.The results showed a significant increase in oil yield with increasing temperature, with the highest yield obtained at 70°C. The yield increased from 26.29% at 30°C to 32.70% at 70°C, indicating a 24.5% increase. The study demonstrates the importance of temperature optimization in coconut oil extraction, providing valuable insights for the industry.This research contributes to the existing body of knowledge on coconut oil extraction, highlighting the potential for process optimization and improved productivity. The findings have important implications for coconut oil manufacturers, providing a basis for the development of more efficient and effective extraction processes.

Abstract

Mild steels composed by two main elements, they are iron (Fe) and carbon (C) elements which is  widely used in industry  because of its resistance and more affordable in terms of cost  than stainless steel, but their weakness is that they have low corrosion resistance. One way to modify mild steel is by coating them with antioxidant compounds that can delay, slow down, and prevent lipid oxidation process, which is obtained from(Chrysophyllum-Albidum) Udara seed extract. This research work is aimed at producing organic corrosion inhibitor from(Chrysophyllum-Albidum) Udara seed extract. Also, to utilize this organic corrosion inhibitor as a substitute for chemical corrosion inhibitors which contain toxic compounds, and determining the corrosion inhibition efficiency of the Udara seed extract in Hydrochloric acid medium. This was carried out by weighing the mild steel pieces. Udara seed extract was also weighed and added into each of the transparent glass bottles that was used in the experiment. However,  10.0g Udara seed powder was added into bottle 1 containing 0.5m of the dilute tetraoxosulphate (vi) acid. 20.0g to bottle 2, containing the same concentration of the  acid.  30.0g to bottle 3, 40.0g to bottle 4, containing 0.5m of the dilute tetraoxosulphate (vi) acid. And 50.0g to bottle 5 containing the same acid, and Finally, bottle 6 was containing the mild steel metal and the dilute tetraoxosulphate (vi) acid. It was observed that the Udara seed extract effectively inhibited mild steel corrosion in H2SO4 solution. Inhibition efficiency was observed to improve with increase in concentration of the extract. It was generally observed that inhibition efficiency was low at the first hour and with the blank and the first concentration and gradually increases by the preceding hours and concentrations. Weight loss increased with increase in time portraying retardation in the inhibitor efficiency with increase in time.

Abstract

This study explores the potential of utilizing agricultural by-products, specifically plantain peels, as a source of caustic potash for producing high-quality black soaps from palm oil and palm kernel oil. The objectives were to evaluate the physicochemical properties and efficacy of these soaps in addressing various skin conditions. Plantain peels were sun-dried, burned, and processed to extract potassium hydroxide, which was then used in soap production. The results show that both soaps exhibited beneficial properties, with the palm kernel oil soap displaying a softer texture. The study highlights the potential of these black soaps in providing effective skincare solutions for common dermatological concerns, while also promoting sustainable utilization of agricultural by-products.

Abstract

This study explores the development of eco-friendly lubricating grease from palm kernel oil with polypropylene additive, adopting a sustainable approach. The research focuses on formulating high-performance greases suitable for industrial and automotive applications. Through experimental synthesis and testing, including worked penetration, dropping point, and water washout resistance, the study evaluates the grease's properties. Results show that the formulated grease with polymer additive exhibits improved thermal stability (dropping point of 187°C) and suitable consistency (worked penetration of 250), meeting NLGI Grade 2 and 3 standards (Table 4.3). The grease also demonstrates excellent water resistance and anti-wear characteristics. This research contributes to sustainable lubrication science, offering a viable alternative to conventional greases and supporting environmentally friendly practices in various industries..

Abstract

This study demonstrates the sustainable production of biodiesel from waste palm oil through alkaline transesterification, utilizing methanol and sodium hydroxide (NaOH) as catalyst. Under optimal conditions (200 ml methanol and 16 g NaOH per liter of waste oil), an 85% biodiesel yield was achieved. The physicochemical properties of the biodiesel, including density (0.87 g/cm³), viscosity (4.5 mm²/s), flash point (160 °C), cetane number (52), and acid value (0.45 mg KOH/g), meet international standards (ASTM D6751, EN 14214). The results show that waste palm oil is a viable, low-cost, and environmentally friendly feedstock, offering a promising alternative to fossil diesel. The study employed a combination of transesterification, settling, and washing processes to produce high-quality biodiesel. This research contributes to sustainable urban waste management and highlights the potential for biodiesel production from waste oils in developing countries, providing a pathway towards renewable energy and reduced environmental impact.

Abstract

This study focuses on enhancing lubricating oil performance through the integration of viscosity improvers in multi-grade blends. A systematic approach was followed to formulate a high-performance multi-grade engine oil, starting with 5 liters of base oil and 1 liter of paraffin oil (100N). Additives (0.42 kg, 7% of the total blend) including Aspen, Tackifier, anti-wear, corrosion inhibitors, detergents, dispersants, and antioxidants were meticulously measured and added to the mix. The mixture was heated to 70°C to facilitate reaction between the base oil and additives, and then cooled to room temperature (around 30°C). Subsequently, 0.5 kg of viscosity index improver was introduced into the mixture, followed by the addition of 5 grams of dye. Quality control tests were conducted to ensure compliance with Standard Organization of Nigeria (SON) standards. The results showed that the product met the stringent specifications outlined by the regulatory body, demonstrating reliability and performance. This study highlights the importance of viscosity improvers in enhancing lubricating oil performance and meeting industry standards.

Abstract

  Boosting carbon capture in coal-fired power plants is crucial for achieving greener energy and mitigating climate change . Pinch analysis, a systematic optimization technique, enhances carbon capture efficiency by minimizing energy consumption and reducing environmental impact. In coal plants, achieving high-purity CO₂ capture is a key objective. Using a 30% MEA (monoethanolamine) solution for carbon capture introduces an initial energy premium of 17.6%. However, applying pinch assessment techniques results in a significant 12.3% reduction in overall energy consumption. This translates to a substantial 50% decrease in energy requirements for carbon capture operations. The implementation of pinch analysis enables coal-fired power plants to achieve an impressive 90% CO₂ capture efficiency, underscoring the potential of this approach to enhance sustainability and cost-effectiveness. By optimizing heat exchange networks and identifying optimal heat transfer points, pinch analysis reduces energy and water consumption in carbon capture processes. This systematic optimization contributes to operational efficiency improvements, paving the way for greener and more sustainable power generation practices. The use of pinch assessment techniques offers a pathway towards cleaner energy production, reduced environmental footprints, and compliance with global climate goals . By strategically matching hot and cold streams, coal plants can minimize resource usage while boosting carbon capture performance.
