汽提器是催化裂化装置的一个重要组成部分,整个催化裂化装置的稳定性和经济效益是由催化裂化汽提性能的优劣决定的,开发效率更高的汽提器是现在一项比较急迫的任务。本文简单的介绍的催化裂化汽提器以及催化剂和蒸汽在汽提器内的运动状况,综述了汽提器的发展,对环形挡板汽提器、环流汽提器、填料汽提器进行的总结。 The stripper is an important part of a catalytic cracking unit. The stability and economic efficiency of the entire catalytic cracking unit are determined by the performance of the catalytic cracking stripper. A more efficient stripper is now a more urgent The task. This paper briefly introduces the catalytic cracking stripper as well as the catalyst and steam movement in the stripper. The progress of the stripper is reviewed. The performance of the stripper stripper, loop stripper, stripper stripper to sum up.
