Process for making ammonia from heterogeneous feedstock |
摘要 |
Ammonia is made from a carbon-containing heterogeneous feedstock by partially oxidizing the feedstock at low pressure to generate a synthesis gas containing CO; isothermally shift reacting the synthesis gas with steam to form H2; cryogenically removing portions of the CO2 and Ar from the shifted gas; purifying the H2 in a pressure swing adsorber; mixing the purified H2 with high purity N2; and converting the H2 and N2 into ammonia. The tail stream from the pressure swing adsorber can be recycled with the synthesis gas for control purposes and/ or used as boiler fuel. The reduced volume of purge gas purged from the ammonia synthesis loop allows ammonia contained in the purge gas stream to be recovered by cryogenic condensing. |
