Author(s) : PETIT P.

Type of article: Article

Summary

HYDROGEN RECOVERY IS EXPECTED TO APPROACH 95 TO 98% BY MEANS OF A SIMPLIFIED LOW TEMPERATURE SEPARATION PROCESS BASED ON PARTIAL CONDENSATION. THE CRYOGENIC PLANT IS SUPPLIED AS A PACKAGE UNIT. THE PURGE GAS IS PROCESSED TO REMOVE THE 2% AMMONIA CONTENT. TWO METHODS HAVE BEEN USED: -AMMONIA CONDENSATION BY COOLING DOWN THE PURGE GAS TO 203 K (-70 DEG C) FOLLOWED BY ADSORPTION AT AMBIENT TEMPERATURE ; -WATER-SCRUBBING OF THE PURGE GAS AT 283 K (10 DEG C) FOLLOWED BY ADSORPTION TO DRY THE GAS AND TO REMOVE THE LAST TRACES OF AMMONIA.
