valve tower

Owing to the particular capacity distribution between the' gas and liquid phases in the recovery tower, floating valve trays should be displaced with tower packings;

因气液相负荷分布特殊，回收塔可采用填料塔代替浮阀塔；

Simulation of the removing butanes tower in ethylene workshop of factory 104 is carried out by computer. Mellapak ( 250Y) structured packing is adopted to replace the initial float valve. The operation is stable after reformation.

对吉化104厂乙烯车间脱丁烷塔进行计算机模拟计算，采用Mellapak（250Y）规整填料改换原浮阀塔版，使得该塔操作稳定，每年节省蒸汽量为6000t，带来很大的经济效益。
