GAS SEPARATION PROCESS FOR PRODUCTION OF HYDROGEN BY AUTOTHERMAL REFORMING OF NATURAL GAS, WITH CARBON DIOXIDE RECOVERY

摘要

Disclosed herein is a gas separation process for the production of hydrogen by autothermal reforming of natural gas, employing a hydrogen separation step and with simultaneous recovery of carbon dioxide using carbon dioxide-selective membrane separation. Residual gas from the hydrogen and carbon dioxide recovery is recycled back to the autothermal reformer.
