Disclosed is a process for the removal of sulfur from a fuel gas stream that additionally contains carbon dioxide and a light olefin as well as an organic sulfur compound. The process includes hydrotreating the fuel gas stream followed by a catalytic reduction of the resulting hydrotreated fuel gas to remove the carbonyl sulfide contained therein that is yielded in the hydrotreating step as a result of the equilibrium reaction of hydrogen disulfide with carbon dioxide to yield carbonyl sulfide and water.
L'invention concerne un procédé d'élimination du soufre contenu dans un flux de gaz de combustion, lequel flux de gaz de combustion contient également du dioxyde de carbone, une oléfine légère et un composé sulfuré organique. Ledit procédé comprend l'hydrotraitement du flux de gaz de combustion puis une réduction catalytique du gaz de combustion hydrotraité ainsi obtenu aux fins d'élimination de l'oxyde sulfure de carbone contenu dans ledit flux gazeux, ledit oxyde sulfure de carbone étant généré à l'étape d'hydrotraitement en raison d'une réaction d'équilibre du disulfure d'hydrogène et du dioxyde de carbone pour produire de l'oxyde sulfure et de l'eau.
