Patent
CA 2449503
A synthesis plant (200) 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 (270) with a refrigerant other than air, or a pressure swing absorption system.
L'invention concerne une installation de synthèse (200) comprenant un système de séparation en amont d'une boucle de synthèse qui enlève des excès d'azote et autres composés gazeux d'un gaz d'alimentation ayant un rapport d'hydrogène/azote inférieur à 3:1, produisant ainsi un gaz de synthèse avec un rapport hydrogène/azote de l'ordre de 3:1. L'invention concerne plus particulièrement les systèmes de séparation préférés comprenant une boîte froide (270) avec un réfrigérant autre que l'air ou un système d'absorption modulée en pression.
