PTA装置催化燃烧系统存在问题和对策

PTA Plant of Catalytic Combustion System Problem and Counter-measurers

文章叙述了PTA装置流程和催化燃烧工艺,指出了系统存在的问题,即甲醇泵切换速度慢,造成装置核心设备空压机联锁。分析了原因,提出了改进措施。取得了较好的效果。系统改造后,因甲醇泵切换造成装置空压机停车的联锁次数大为减少。

The paper described the PTA plant process and catalytic combustion process, found out the problems existing in the system .methanol pump switching speed is low, cause air compressor interlock. We analyzed the cause of it, the improvement measure were put forward, achieved good results. After the system redevelop, because methanol pump caused by switching the plant stops was great reduced.
