the crude oil, crude protein, crude ash, crude fiber, total phenol and antioxidant activity values, peroxide values, specific gravity, the refraxtive index and  acid value of citrullus lanatus and their oils were determined. fatty acid composition of seeds belong to both watermelon were determined by gas chromotography (gc). these oils are important sources of essential fatty acid, linoleic aci...

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 the petrochemical industry, certain elements are known to impact the performance and value of the final product, while others have detrimental effects on petroleum refining processes, as in the case of elements which can deactivate or poison catalysts. Consequently, there are several ASTM methods on the elemental analysis of oils, lubricants and fuels. Multi-Element Analysis of Petroleum Cru...

The crude oil, crude protein, crude ash, crude fiber, total phenol and antioxidant activity values, peroxide values, specific gravity, the refraxtive index and  acid value of Citrullus lanatus and their oils were determined. Fatty acid composition of seeds belong to both watermelon were determined by Gas Chromotography (GC). These oils are important sources of essential fatty acid,...

This study compared the profiles of fatty acids, phytosterols, and polyamine conjugates in conventional commercial corn oil extracted from corn germ and in two ‘‘new-generation’’ corn oils: hexane-extracted corn fiber oil and ethanol-extracted corn kernel oil. The fatty acid compositions of all three corn oils were very similar and were unaffected by degumming, refining, bleaching, and deodoriz...
