Effluent Treatment Plant (ETP) ¨C Aqua Refinery
Process water emanates from refinery units (AD, VD, FCC ,HDS, miscellaneous cracking, visbreaking¡). Effluent produced by desalinators and the FCC (catalytic crackers) are the most saline and often polluted with sulphides which justifies a preliminary stripping and/or oxidation treatment before undergoing oil removal by flotation and biological treatment.

Refining Vegetable Oils: Chemical and Physical Refining
The bleaching is a critical step in the refining process of oils [ 57, 58 ], preceded generally by degumming, neutralization, and drying processes. Bleaching is a complex physical and chemical process employed in the refining of vegetable oils. The objective of bleaching (or decolorizing) is to reduce the levels of colored pigments (carotenoids

Advances in Treatment of Vegetable Oil Refining Wastes
Refining of edible oil is a process where free fatty acids are volatilized, condensed, and recovered simultaneously with vacuum decoloring operation. However, processes in vegetable oil refining, such as filter backwash, acidification of soap-stock, and washing of equipment, produce big amounts of wastewaters [ 5 ].
