Abstract:

Oil extraction in Nigeria has caused extensive environmental degradation and health problems in many Nigerian communities, particularly in the ecologically sensitive Niger Delta where nearly all of the oil extraction takes place. The reasons for this are complex and have roots in Nigeria’s colonial past. The Nigerian economy is largely reliant on its petroleum resources which, in conjunction with governmental corruption and high international demand for Nigerian oil, has created a system where environmental externalities are largely ignored. Multinational oil companies with little stake in the

Abstract:

Organosulfur compounds are amongst the most problematic components present in crude oil which has a direct influence on the performance of the refinery processes as well as during storage, transportation and separation. The presence of sulfur species in fuels are clearly a major issue in air pollution, airborne particulate emissions and endangering health public. The sulfur content of crude oil is an important characteristic which effects the oil price. Catalytic approaches for sulfur removal, such as hydrodesulfurisation (HDS), are the most commonly applied techniques. Aromatic S-compounds in

Sustainable biodiesel can be produced by processing vegetable oil seeds or microalgae. The processing includes numerous processes which impact the quality and cost of the final product. Oil extraction from the feedstock is one of the most energy intensive parts of the process in the production chain. Oil extraction methods are influenced by the operational physical parameters or chemical characteristics, and their selection greatly impacts the final oil yields.

Abstract:

Cranberry seed oil is a fine quality oil which can be marketed for its many beneficial functions to human health due to the presence of a unique combination of omega- 3, 6 and 9 fatty acids and the high concentration of antioxidants. Although there is no available clear data about the oil percentage of cranberry seeds in literature, an experiment was done to analyze the oil yields obtained through different processes such as heat reflux, microwave and ultrasound, both quantitatively and qualitatively. During preliminary experiments, better oil yields were obtained with ground seeds (10.11 ± 0.

It is anticipated that resources from extra-heavy oils and bitumen may resolve the expected future escalation in oil demand. Such oils are usually recovered by thermal methods, however these can be energy intensive, especially for reservoirs with thin net-pay or those bounded with large aquifers or gas caps. This is primarily due to excessive heat losses. On the other hand, VAPour EXtraction of heavy oil (VAPEX) is a more energy-efficient, economically attractive and pollution-free alternative, especially for these problematic scenarios.

Abstract:

A large number of herb materials contain Essential Oils with extensive bioactivities. Acknowledging the importance of plants and its medicinal value, extraction of Essential Oil had been done using Steam Distillation method. In this project Steam Distillation was used to extract oil from different plant materials like eucalyptus leaves, curry leaves, hibiscus leaves, lemon leaves, marigold flowers, rose flowers, orange peels etc. Research has confirmed centuries of practical use of essential oils, and we now know that the 'fragrant pharmacy' contains compounds with an extremely broad range of

Abstract:

Essential oils are highly concentrated substances extracted from flowers, leaves, stems, roots, seeds, barks, resins, or fruit rinds. These oils are often used for their flavor and their therapeutic or odoriferous properties, in a wide selection of products such as foods, medicines, and cosmetics. Extraction of essential oils is one of the most time- and effortconsuming processes. The way in which oils are extracted from plants is important because some processes use solvents that can destroy the therapeutic properties. There are wide number of ways to extract the Essential oil but the quality

碩士<br>國立臺灣大學<br>生物產業機電工程學研究所<br>94<br>Rapeseed oil is one the major feed stocks for biodiesel with great potential. The feasibility and efficiency of various rapeseed oil extraction systems with hexane, ethanol and water as solvents were studied and compared. Mathematical model of multi-stage counter-current-flow extraction was build and verified in this research. Six-stage counter-current-flow extraction experiments were carried with two different solvent to raffinate ratio (E/R) i.e. E/R=4, 8. A better result was found with E/R=4, that gave 90% in oil recovery and 8~9% (w/w) oil concentratio

Abstract:

Soybean oil was extracted from soybean flakes and porous alumina spheres by hexane and isopropanol. Extraction of oil from alumina spheres was normal in terms of appropriate PDE solutions of Fick's second law of diffusion. Extraction of oil from flakes agreed with Fick's second law of diffusion for short extraction times, but deviated significantly from the standard diffusion behavior at long times. In spite of its apparent complexity, the solvent extraction of oil from flaked oilseeds appears to be a linear diffusion process and the diffusivity appears to be independent of oil concentration.
