Title (EN) METHOD AND APPARATUS FOR ELIMINATING POLLUTANTS FROM A GAS STREAM
(FR) PROCÉDÉ ET APPAREIL POUR ÉLIMINER DES POLLUANTS D'UN FLUX DE GAZ
Abstract: front page image
(EN)The present invention is directed to method of eliminating gaseous pollutants in a gas stream (12), such as flue gas stream, by reacting the gaseous pollutants with hydrogen sulfide (H2S) (24) in the presence of a catalyst (20) under conditions sufficient to convert the gaseous pollutants into products including one or more of elemental nitrogen, elemental sulfur, and water. In one embodiment, the invention is directed to a method of eliminating gaseous pollutants in a gas stream in which the gaseous pollutants include one or more of NOx, SOx, and combinations thereof. Additional pollutants that may be present in the gas stream and that may be eliminated in accordance with embodiments of the present invention include ozone (03) and carbonyl sulfide (COS).
(FR)La présente invention concerne un procédé d'élimination de polluants gazeux dans un flux de gaz (12), tel qu'un flux de gaz d'évacuation, par réaction des polluants gazeux avec du sulfure d'hydrogène (H2S) (24) en présence d'un catalyseur (20) dans des conditions suffisantes pour convertir les polluants gazeux en produits comprenant un ou plusieurs de l'azote élémentaire, du soufre élémentaire, et de l'eau. Dans un mode de réalisation, l'invention concerne un procédé d'élimination de polluants gazeux dans un flux de gaz dans lequel les polluants gazeux comprennent un ou plusieurs de NOx, SOx, et des combinaisons de ceux-ci. Des polluants additionnels qui peuvent être présents dans le flux de gaz et qui peuvent être éliminés selon des modes de réalisation de la présente invention comprennent l'ozone (O3) et le sulfure de carbonyle (COS).
