PROCESS FOR PRODUCING AMMONIA OR METHANOL AND A GASIFIER USED IN SAID PROCESS

摘要

A process for producing ammonia or methanol and a gasifier used in said process in which the gasifier operates to produce a synthesis gas which is continuously passed to a reactor and a cooler in a closed loop configuration. Ammonia or methanol is produced at the cooler along with a methane rich off-gas. A portion of the latter gas is removed from the loop and is routed back to the gasifier, where the methane therein is converted to produce heat and therefore increase the efficiency of the process.
