摘要： A system and method for cryogenic purification of a hydrogen, nitrogen, methane and argon containing feed stream to produce a methane free, hydrogen and nitrogen containing synthesis gas and a methane rich fuel gas, as well as to recover an argon product stream, excess hydrogen, and excess nitrogen is provided. The disclosed system and method are particularly useful as an integrated cryogenic purifier in an ammonia synthesis process in an ammonia plant. The excess nitrogen is a nitrogen stream substantially free of methane and hydrogen that can be used in other parts of the plant, recovered as a gaseous nitrogen product and/or liquefied to produce a liquid nitrogen product.

摘要： A synthesis plant includes a separation system upstream of a synthesis loop that removes excess nitrogen and other gaseous compounds from a feed gas having a ratio of hydrogen to nitrogen of less than 3:1, thereby producing a syngas with a ratio of hydrogen to nitrogen at about 3:1. Particularly preferred separation systems include a coldbox with a refrigerant other than air, or a pressure swing absorption system.

摘要： A gas mixture comprising carbon dioxide, at least one gas having a lower boiling point than carbon dioxide, and at least one gaseous impurity having a higher boiling point than carbon dioxide (the impurity typically being hydrogen sulphide) is purified by a rectification process. The gas mixture (typically with a carbon dioxide partial pressure of 20 atmospheres) is precooled to the dewpoint of the carbon dioxide or below and is then rectified to form a liquid fraction relatively rich in the impurity or impurities and a product gaseous fraction relatively lean in or free from the gaseous impurity or impurities. The liquid fraction may be subjected to a second rectification to yield pure carbon dioxide.
