The fault analyses were made of the propylene circulating gas compressors. It was concluded that the major causes were that some fluid and powder materials entered the compressor system.

对丙烯循环气压缩机的故障情况进行了分析，认为压缩机带液及粉料进入压缩机系统是造成该机故障的主要原因。

The results show that an appropriate quantity of circulating water exists under certain conditions in the system and decreases with a reduction in the steam gas ratio of the shift reaction.

结果表明，系统在一定条件下存在一较为适宜的循环水量，且此适宜的循环水量随变换反应汽气比的降低而降低。
