Process and apparatus for converting crude oil with improved product yield into petrochemical products

摘要

The present invention relates to an integrated process for converting crude oil, including crude oil distillation, hydrocracking and steam cracking, into petrochemical products, which process includes gas fractions, naphtha, kerosene, Crude distillation of the crude oil to produce a propellant; Upgrading the residual oil to produce LPG, light oil and middle-distillate; Partially hydrogenating or hydrolyzing one or more of the group consisting of intermediate oil, kerosene and light oil produced by residual oil upgrading to produce LPG, light oil and hydro wax; And steam cracking one or more or all of the group consisting of light oil produced by residual oil upgrading, light oil produced by intermediate olehydrogenolysis and hydro waxes. In addition, the present invention relates to a process apparatus for carrying out the process of the present invention. The process and process apparatus of the present invention allows crude oil to be converted to petrochemicals with improved carbon yield and carbon-efficiency while maintaining a favorable ethylene: propylene ratio.
