Decarbonisation of large ammonia plants using the dual high pressure adsorption process can be seen as using PSA decarbonisation as a pre-treatment unit for PSA purification of hydrogen and nitrogen. The process is to first remove the conversion gas to obtain 98% (v) decarbonised gas for urea and other processes and then to enter the PSA purification small air separation unit to obtain C02 0.02% (v) hydrogen and nitrogen as the feed gas for ammonia synthesis.   The choice of pretreatment ...
