Title (EN) WASTE GAS TREATMENT SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE DE TRAITEMENT D'EFFLUENTS GAZEUX
Abstract:
(EN) The gas stream which is produced in and emanates from landfills, anaerobic digesters and other waste gas streams is treated to produce a purified gas which is essentially a hydrocarbon such as methane and which can be used as the fuel source in a fuel cell power plant. The gas stream passes through a simplified purification system which removes essentially all of the sulfur compounds, hydrogen sulfide, and halogen compounds from the gas stream. The resultant gas stream can be used to power a fuel cell power plant which produces electricity, or as a hydrocarbon fuel gas for other applications.
(FR) On traite le flux de gaz qui est produit et dégagé par des décharges, des digesteurs anaérobies et d'autres flux d'effluents gazeux, pour produire un gaz purifié qui est essentiellement un hydrocarbure tel que le méthane et qui peut être utilisé comme source de combustible dans une centrale à piles à combustible. Le flux de gaz passe dans un système de purification simplifié qui enlève sensiblement tous les composés sulfurés, l'hydrogène sulfuré et les composés halogénés du flux de gaz. Le flux de gaz résultant peut être utilisé pour alimenter une centrale à piles à combustible produisant de l'électricité, ou en tant que gaz combustible hydrocarburé.
