Abstract: Aspen Plus software is employed to simulate the quench system of ethylene unit of PetroChina Fushun Petrochemical Company.The proposed main method that lowers the gasoline dry point is to increase side drawing output of the quench oil column in order to reduce gasoline circulation.It is found that reducing gasoline circulation can increase bottom temperature of the quench oil column,therefore increases dilution steam generation amount.On the premise of guaranteeing the top temperature of quench oil column,the pan oil circulation shall be as small as possible to improve energy efficiency.The mean temperature difference of heat transfer can be increased by reducing circulation amount of quench oil,which is more beneficial for recovering heat from quench oil.
