变压吸附解吸气的回收利用

Recovery and Utilization of PSA Relief Gas

主要研究变压吸附分离甲醇裂解气后的解吸气,通过压缩、提纯等工艺加以回收利用,并应用于实践,回收99.99％氢气175Nm^3/h,氢气总收率由70％提高到82％,取得了良好的经济效益。

This paper studies recovery and Utilization of PSA relief gas. It's recovered by compressing and refining, the amount of recoverable hydrogen is 175Nm3/h, hydrogen yield is raised from 70% to 82% . The teohnology has good economic efficiency.
