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.展开更多
