PROCESS FOR THE PRODUCTION OF HYDROGEN AND CARBON DIOXIDE

摘要

A process for producing hydrogen and capturing carbon dioxide from a hydrocarbon containing feed stream comprising a methane reformer unit, a water gas shift reactor, hydrogen purification in a process unit (0) to obtain a hydrogen product stream (27), a first hydrogen selective membrane separation unit (4) to form a first hydrogen rich permeate stream (5), a carbon dioxide separation unit (8) to produce a carbon dioxide rich liquid stream (9), a second hydrogen selective membrane separation unit (11) to form a second hydrogen rich permeate stream (12), and a carbon dioxide selective membrane separation unit (14) to form a carbon dioxide enriched permeate stream (15).
