Process to prepare a diluted hydrogen gas mixture |
摘要 |
Process to prepare a diluted hydrogen gas mixture starting from a gas mixture comprising hydrogen and carbon monoxide by (i) converting part of the carbon monoxide in said gas mixture to hydrogen and carbon dioxide by means of a catalysed water gas shift reaction to obtain a shifted gas and (ii) separating hydrogen from said shifted gas by means of a membrane to obtain the hydrogen comprising gas at the permeate side of the membrane and a carbon dioxide comprising gas at the retentate side of the membrane, wherein at the permeate side of the membrane a sweep gas is provided; (iii) cooling the carbon dioxide comprising gas to obtain liquid carbon dioxide and a gas mixture of non-condensable gasses and (iv) separating the liquid carbon dioxide from the non-condensable gasses; wherein the non-condensable gasses are fed into the hydrogen comprising gas. |
