process for ammonia synthesis

摘要

a process for the synthesis of ammonia comprising the steps of reforming a hydrocarbon feedstock into a crude product gas, purifying said crude product gas obtaining a compensating synthesis gas, converting said synthesis gas to ammonia; said purification includes conversion of carbon monoxide transfer to carbon dioxide and the reforming process requires a heat input that is at least partially recovered from said transfer conversion step, which is performed at a peak temperature of at least 450 ° C, and said ammonia conversion step.
