butanes

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。

Butanes and butenes can be maintained in the liquid states ambient temperature under quite moderate pressure.

在适当的大气压力及常温下,丁烷和丁烯均可保持液体状态.

A flammable alcohol derived from butanes and used for solvents.

一种易燃的醇，由丁烷衍生而来，用作溶剂。

Therefore, it is necessary to extend the resource of isobutene by dehydrogenation of butanes.

因此，通过异丁烷脱氢扩大异丁烯的来源是必要的。
