Simultaneous refining and dewaxing of crude vegetable oil

Abstract: A process for refining and dewaxing crude vegetable oils using only one separation step which removes both the hydrophilic and waxy components from the crude oil An alkali refining/dewaxing treatment is employed on crude oil at a temperature of from about 15°F to about 45°F

Increased production of diesel oil and fuel oil

Abstract: The effluent from a catalytic cracking reactor is fractionated to produce a plurality of streams including a heavy cycle oil and a decant or residual oil. The residual oil is employed to quench the effluent from a cracking furnace in which a light hydrocarbon is thermally cracked. A light oil recovered from the quench step is returned to the fractionator, either directly or through a heavy cycle oil stripper, to increase diesel oil and fuel oil production.
