酸性气体脱除系统冷量回收的技术改造

TECHNICAL REFORMATION ON COLD ENERGY RECOVERY FROM RECTISOL UNIT

为解决酸性气体脱除系统冷量在运行过程中回收利用不平衡不充分的问题,对酸性气体脱除系统进行技术改造,在贫富液换热器的冷区增加绕管式换热器。改造后,充分回收了酸性气体脱除系统的冷量,提高了装置的生产负荷,增加了生产效益,实现了多方面的节能降耗。

In order to solve the problem of the unbalanced and insufficient recovery and utilization of cold energy in the rectisol unit,the technical reformation was carried out by adding a coil-wound heat exchanger in the cold area of the lean-rich liquid heat exchanger.After the reformation,the cold energy in the rectisol unit was fully recovered.The production load of the device and its benefit were increased,and the goal of energy saving and consumption reduction was achieved.
