  • Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)

Abstract

PURPOSE: To smooth the operation of the circulation system, and to maintain the whole system efficient, by circulating a mixture of a feed heavy oil and bottoms of a solvent extraction column after catalytic hydrotreating step through the step.
CONSTITUTION: The heavy oil 1 is mixed with the bottom 11 of the solvent extraction column in the container A thoroughly, and the solvent is evaporated in the heating furnace B to form the mixed-phase substance 6, which is fed to the asphalt flash drum C. The raw mixed liquid stream 7 is mixed with the hydrogen gas 19 and reaction gas 20 rich in hydrogen, and then fed to the hydrotreating reactor D to effect liquid-gas separation of the product 9 in the separator E. The liquid product 10 is mixed with the solvent 16, and fed to the solvent extraction column F. The deasphalted oil 18 rich in the solvent is fed into the flash drum G to recover the solvent 14, and the deasphalted oil 22 is taken out as a product oil.
