Bentonitic material from South Aswan, Egypt was evaluated in terms of mineral-ogy and chemical composition as bleaching clay in refining of transformer oil before and after acid activation and thermal treatment followed by acid leaching using HCl and H2SO4 for different contact times. Structural modification and refining power of bento-nite were investigated during modification by means of X-ra...

Crude oil blending is an important unit operation in petroleum refining industry. There are two difficulties for commercial crude oil optimizing controllers: (1) the optimization is stable only in some special conditions, the simplex-base algorithm is not robust; (2) the optimal control should be realized on-line and it cannot be analyzed off-line based on the history data. In this paper, we pr...

Oil from brebra (Millettia ferruginea) is the potential raw material for biodiesel production. The refining of crude oil requires a series of purification steps to produce quality biodiesel. The objective of the study was to produce refined oil from brebra seed for biodiesel production. Crude oil extraction was carried out using mechanical press and solvent extraction methods. Impurities of the...
