ABSTRACT:
A method of refining crude oil by distillation and desulfurization for the preparation of petroleum products can reduce cost of apparatus and cost of operation and can be operated with better stability by simplified control of operation. In the method, a naphtha fraction is separated from crude oil by distillation, the residual fraction which remained after the naphtha fraction has been removed from the crude oil is hydrodesulfurized and the hydrodesulfurized fraction is separated into further fractions by distillation. A kerosene fraction and a gas oil fraction of high quality can be obtained and yields of intermediate fractions such as kerosene and gas oil can be increased by introducing a hydrotreating process, a high pressure separation process and a residue fluid catalytic cracking process in a sophisticated way for refining of the residual fraction remained after the naphtha fraction has been removed from the crude oil.
