Title (EN) PROCESS FOR PRODUCING A PURIFIED SYNTHESIS GAS STREAM
(FR) PROCÉDÉ DE PRODUCTION D'UN COURANT DE GAZ DE SYNTHÈSE PURIFIÉ
Abstract:
(EN) A process for producing a purified synthesis gas stream from a feed synthesis gas stream comprising besides the main constituents carbon monoxide and hydrogen also hydrogen sulphide, HCN and/or COS, the process comprising the steps of : (a) removing HCN and/or COS by contacting the feed synthesis gas stream with a catalyst in a HCN/COS reactor in the presence of steam/water, to obtain a synthesis gas stream depleted in HCN and/or in COS; (b) converting hydrogen sulphide in the synthesis gas stream depleted in HCN and/or in COS to elemental sulphur, by contacting the synthesis gas stream with an aqueous reactant solution containing solubilized Fe(III) chelate of an organic acid, at a temperature below the melting point of sulphur, and at a sufficient solution to gas ratio and conditions effective to convert H2S to sulphur and inhibit sulphur deposition, to obtain a synthesis gas stream depleted in hydrogen sulphide; (c) removing carbon dioxide from the synthesis gas stream depleted in hydrogen sulphide, to obtain the purified synthesis gas stream and a gas stream enriched in CO2.
(FR) L'invention porte sur un procédé de production d'un courant de gaz de synthèse purifié à partir d'un courant de gaz de synthèse d'alimentation comprenant, en dehors des constituants principaux monoxyde de carbone et hydrogène, également du sulfure d'hydrogène, HCN/ou COS. Le procédé comprend les étapes consistant à : (a) retirer HCN et/ou COS par mise en contact du courant de gaz de synthèse d'alimentation avec un catalyseur dans un réacteur HCN/COS en présence de vapeur d'eau/eau, afin d'obtenir un courant de gaz de synthèse appauvri en HCN et/ou en COS ; b) convertir en soufre élémentaire le sulfure d'hydrogène dans le courant de gaz de synthèse appauvri en HCN et/ou en COS, par mise en contact du courant de gaz de synthèse avec une solution aqueuse de réactif contenant un chélate de Fe(III) solubilisé d'un acide organique, à une température au-dessous du point de fusion du soufre, et à un rapport solution à gaz suffisant et dans des conditions efficaces pour convertir H2S en soufre et inhiber le dépôt de soufre, afin d'obtenir un courant de gaz de synthèse appauvri en sulfure d'hydrogène ; (c) retirer le dioxyde de carbone du courant de gaz de synthèse appauvri en sulfure d'hydrogène, afin d'obtenir le courant de gaz de synthèse purifié et un courant de gaz enrichi en CO2.
