摘要/Abstract

摘要：

将2种横管初冷器下段离线清洗技术进行阐述和比较，一种方法是采用热氨水离线一次清洗，另一种方法是采用洗油、苯类混合液离线循环清洗，为焦化厂不同原因的横管初冷器下段堵塞情况提供合适的解决对策。

Abstract:

Two kinds of technologies are introduced and compared for off-line cleaning of lower-section of cross-tube primary cooler,i.e.one is off-line cleaning with hot ammonia liquor,and the other is off-line circulating cleaning with washing oil and benzene mixture,which provide appropriate solutions to the blockage at lower-section due to different reasons for the cross-tube primary cooler in the coking plant.

Key words: Cross-tube primary cooler, Lower-section, Off-line, Cleaning
