This paper addresses procurement planning in oil refining, which has until now only had limited attention in the literature. We introduce a mixed integer nonlinear programming (MINLP) model and develop a novel two-stage solution approach, which aims at computational efficiency while addressing the problems due to discrepancies between a non-linear and a linearized formulation. The proposed mode...

in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...
Solvent extraction, an innovative adaptation of existing crude oil refining technology, is being
The chlorophyll content of canola oil, especially when extracted from frost-damaged seed is high, and results in dull, dark brown oil unless very large quantities of bleaching clay are used. We found that treatment with phosphoric acid, under vacuum in the absence of moisture precipitates most of the chlorophyll. At 140°C 2400 mg/L phosphoric acid precipitated 98 % of the chlorophyll in canola ...
Due to its large number of potential utilizations Jatropha curcas L. (physic nut, purging nut), a tropical plant cultivated in many Latin American, Asian and African countries, has become topic of various research projects. Nutritional as well as technical applications, however, are restricted due to the plant’s toxicity. The seed oil contains phorbol esters, a family of compounds known to caus...
In the present study, the aflatoxin B1 contamination at various stages of oil refining and in refined oil were carried out. This was subsequently compared with commercial vegetable oil samples. Among the 23 different sunflower oil samples were tested, 10 of them showed positive results to AFB1 and the remaining 13 showed negative results to AFB1. All the refined oil samples were free from AFB1 ...
