Title (EN) METHOD FOR REMOVAL OF SULFUR COMPOUNDS FROM A GAS STREAM
(FR) PROCÉDÉ D'ÉLIMINATION DE COMPOSÉS SOUFRÉS À PARTIR D'UN FLUX GAZEUX
Abstract:
(EN) A process is disclosed for the removal of low molecular weight sulfur containing compounds from a gas feedstream, preferably a natural gas feedstream. The process provides for passing a gas feedstream comprising low molecular weight sulfur containing compounds though a regenerable adsorbent media which adsorbs low molecular weight sulfur containing compounds to provide a low molecular weight sulfur containing compounds-lean gas product and a low molecular weight sulfur containing compounds-rich adsorbent media. The regenerable adsorbent media of the present invention is a cross- linked macroporous polymeric adsorbent media.
(FR) L'invention concerne un procédé d'élimination de composés contenant du soufre en faible poids moléculaire à partir d'un flux d'alimentation en gaz, de préférence un flux d'alimentation en gaz naturel. Le procédé consiste à faire passer un flux d'alimentation de gaz comprenant des composés contenant du soufre en faible poids moléculaire à travers un milieu adsorbant régénérable qui adsorbe des composés contenant du soufre en faible poids moléculaire pour fournir un produit gazeux pauvre en composés contenant du soufre en faible poids moléculaire et un milieu adsorbant riche en composés contenant du soufre en faible poids moléculaire. Le milieu adsorbant régénérable de la présente invention est un milieu adsorbant polymérique macroporeux réticulé.
