ABSTRACT:
A process for the energy efficient conduct of a multi-stage water gas shift reaction includes furnishing a carbon monoxide-containing feed gas stream at an inlet temperature of at least 600.degree. F. and water to a high-temperature shift reactor stage to produce a carbon dioxide and hydrogen enriched exhaust gas stream and introducing the exhaust gas stream to a low-temperature shift reactor stage at an inlet temperature of about 300.degree.-500.degree. F. to produce a product gas stream further enriched in carbon dioxide and hydrogen. A heat exchange fluid is passed in heat exchange relationship with at least the feed and exhaust gas streams to recover thermal energy therefrom by concurrently cooling the gas streams and heating the heat exchange fluid. Desirably, a water heat exchange fluid is heated by the gas streams to superheated steam which is expanded through a steam turbine coupled to a generator to produce electrical energy and the steam turbine exhaust steam is directed to the high temperature shift reactor to provide the water feed thereto.
