Title (EN) METHOD OF REMOVING AND RECOVERING ELEMENTAL SULFUR FROM HIGHLY REDUCING GAS STREAMS CONTAINING SULFUR GASES
(FR) PROCEDE D'EXTRACTION ET DE RECUPERATION DU SOUFRE ELEMENTAIRE D'ECOULEMENT GAZEUX FORTEMENT REDUCTEURS QUI CONTIENNENT DES GAZ SOUFRES
Abstract: front page image
(EN)A method is provided for the removal of sulfur compounds out of feed gases, such as synthesis gas or coal gas, and the recovery of elemental sulfur from the sulfur compounds, by contacting the feed gas with a catalyst, that is either activated carbon or an oxide-based catalyst, and an oxidant, such as sulfur dioxide, in a reaction medium (1) to convert the sulfur compound in the feed gas into elemental sulfur. The elemental sulfur is recovered by separating it from the reaction medium (1).
(FR)L'invention concerne un procédé visant à extraire des composés soufrés de gaz d'alimentation, p. ex. gaz de synthèse ou gaz de houille, et à récupérer le soufre élémentaire desdits composés, par la mise en contact du gaz d'alimentation avec un catalyseur, lequel est soit du charbon activé, soit un catalyseur à base d'oxyde, et un oxydant, p. ex. dioxyde de soufre, dans un milieu réactionnel (1) afin de transformer en soufre élémentaire le composé soufré présent dans le gaz d'alimentation. On récupère le soufre élémentaire en le séparant du milieu réactionnel (1).
