Resumen de: CA3268521A1
In a process in which ammonia is cracked to form a hydrogen gas product and an offgas comprising nitrogen gas, residual hydrogen gas and residual ammonia gas, residual ammonia is recovered from the offgas from the hydrogen recovery process by partial condensation and phase separation, and hydrogen is recovered from the resultant ammonia-lean offgas by partial condensation and phase separation. The recovered ammonia may be recycled the cracking process and the recovered hydrogen may be recycled to the hydrogen recovery process to improve hydrogen recovery from the cracked gas. Overall hydrogen recovery from the ammonia may thereby be increased to over 99%.
