在企业的发展中,为了获得一定的经济利益,某个企业在全厂的操作装置进行了优化,其主要目的就是将催化装置加工符合进行提升,从而将实际生产中的渣油总量进行降低,以此来提升轻液气体回收率。在这当中提升掺渣的最主要问题就是取热能力。因此本文主要就对催化裂解装置外取热器存在问题及应对措施进行分析和探讨。 In the development of enterprises, in order to obtain certain economic benefits, a company in the whole plant operating device has been optimized, the main purpose is to match the catalytic device processing to enhance, so as to reduce the total amount of residual oil in actual production , In order to improve light liquid gas recovery rate. In this process, the most important problem in upgrading dross is the ability to remove heat. Therefore, this paper mainly on the catalytic cracking unit outside the heat exchanger problems and countermeasures for analysis and discussion.
