Process

Raw oil from the tank farm via a pump (P-101) pumped to the device through the heat exchanger about 100 ℃ pretreatment equipment handle backward into raw buffer tank (D-101), then the pump (P-102) to the other heat exchanger is heated to 240 ℃ or into the flash tank (D-102) dehydrated raw oil through the pump after dehydration (P-103) evacuated to a pressure furnace (F-101) was heated to 380 ~ 400 ℃ into fractionator (T-101) fractionation to separate the exhaust gas, gasoline, diesel, atmospheric gas oil, and often base oil, then into the vacuum tower bottoms often (T-102) vacuum distillation to separate the vacuum gas oil and the residual oil, atmospheric gas oil and vacuum gas oil feed with lysis buffer tank (D-103), and then pumped to a cracking furnace (F-102) was heated to 380 ~ 430 ℃ to the reactor (R-101 ) catalytic cracking reaction, the reaction product with atmospheric furnace (F-101) out of the raw oil into the fractionating column with (T-101) fractionation, after which the cooling of the distillate heat exchanger means.
