催化裂化的工艺特点所带来的高温与油气环境,决定了结焦倾向是客观存在的,而重油催化裂化装置表现的则更为严重和普遍。本文试图根据结焦原理、结焦的不同部位,提出相应的措施,以尽量减少结焦程度,延长操作周期,提高装置的经济效益。 Catalytic cracking process characteristics brought about by the high temperature and oil and gas environment, the coking tendency is an objective reality, while the performance of heavy oil catalytic cracking unit is more serious and widespread. This paper attempts to caking according to the principle of different parts of coking, put forward corresponding measures to minimize the degree of coking, extend the operating cycle and improve the economic efficiency of the device.
