本文主要叙述影响FCC气体回收装腐蚀的因素、监测腐蚀的方法和减缓腐蚀所应用柏化学缓蚀剂.流化催化裂化(FCC)气体回收装置的效率会随着腐蚀、结垢而大幅度下降.本文联系装置实际存在的问题,讨论了FCC的气体腐蚀的基本原理(包括氢鼓泡的断定、控制与监测).一般的金属损失、麻点、冲蚀和混积物层下浸蚀等问题,以便能够有效地加以解决. This article describes the factors that affect the corrosion of the FCC gas recovery unit, the methods of monitoring corrosion, and the corrosion inhibitors used in cypress chemistry. The efficiency of fluid catalytic cracking (FCC) gas recovery units drastically declines with corrosion and fouling This article addresses the actual problems with the installation and discusses the basic principles of FCC gas corrosion (including determination of hydrogen bubbling, control and monitoring), general metal loss, pitting, erosion and etchability on concretions Problem so that it can be effectively addressed.
