NITROGEN SWEEP GAS IN HYDROGEN SEPARATION MEMBRANE FOR PRODUCTION OF H2/N2 FUEL GAS

The present invention relates to the use of low pressure N2 from an air separation unit (ASU, 100) for use as a sweep gas in a hydrogen transport membrane (HTM, 114, 126) to increase syngas H2 recovery and make a near-atmospheric pressure (less than or equal to about 25 psia) fuel for supplemental f...

Zusammenfassung:	The present invention relates to the use of low pressure N2 from an air separation unit (ASU, 100) for use as a sweep gas in a hydrogen transport membrane (HTM, 114, 126) to increase syngas H2 recovery and make a near-atmospheric pressure (less than or equal to about 25 psia) fuel for supplemental firing in the heat recovery steam generator (HRSG) duct burner (132). La présente invention concerne l'utilisation de N2 basse pression à partir d'une unité de séparation d'air (ASU) destiné à être utilisé comme gaz de balayage dans une membrane de transport d'hydrogène (HTM) pour augmenter la récupération de gaz de synthèse H2 et créer un combustible d'une pression proche de la pression atmosphérique (inférieure ou égale à environ 25 psia) en vue d'une combustion supplémentaire dans le brûleur de conduit du générateur de vapeur à récupération de chaleur (HRSG).
