論文簡介

The comprehensive evaluation of Tahe medium gravity crude has demonstrated that this type of crude belongs to a intermediate base sour crude, featuring high vanadium content (103ppm), high carbon residue content, low pour point, and low acid value. Based on the crude processing conditions at SINOPEC Luoyang Petrochemical Branch Company, a proposal on the appropriate process flow scheme for processing Tahe crude oil has been raised with the main ideas presented as follows. The IBP-175 ℃ fraction is not an ideal feedstock for catalytic reforming; the 75-250℃ fraction is a qualified feedstock for zeolite de-waxing; the 140-230℃ fraction can be used to manufacture the No. 3 jet fuel through appropriate distillation range adjustment and product refining; the 175-350℃ fraction can be directly used to manufacture No.-10 diesel through proper refining; the atmospheric resid boiling over 350℃ is not suited to be used as the RFCC feedstock; the 350-520℃ vacuum distillate oil can be used as the FCC feedstock; and the vacuum residuum boiling over 520℃ is a good feedstock for manufacture of asphalt.
