Title (EN) A FLUIDIZED BED SYSTEM FOR REMOVING MULTIPLE POLLUTANTS FROM A FUEL GAS STREAM
(FR) SYSTÈME À LIT FLUIDISÉ SERVANT À ÉLIMINER LES POLLUANTS CONTENUS DANS UN COURANT DE COMBUSTIBLE GAZEUX
Abstract:
(EN) A system includes an adsorber having a fuidized bed of a plurality of adsorption materials. The adsorber is configured to receive the gaseous fuel stream including the plurality of pollutants and adsorb the said plurality of pollutants in a single unit from the gaseous fuel stream to generate a clean gas stream substantially free of the pollutants. Different adsorption materials are designed to remove different pollutants over a similar temperature range. The pollutants include at least one of sulfur compounds, chlorine, ammonia, mercury, arsenic, selenium, cadmium, or combinations thereof.
(FR) L'invention concerne un système comportant un adsorbeur pourvu d'un lit fluidisé constitué d'une pluralité de matériaux d'adsorption. L'adsorbeur est conçu pour recevoir un courant de combustible gazeux contenant une pluralité de polluants et pour adsorber dans une seule unité ladite pluralité de polluants contenue dans le courant de combustible gazeux de manière à produire un courant gazeux propre sensiblement exempt de polluants. Les différents matériaux d'adsorption sont destinés à éliminer les différents polluants sur une plage similaire de températures. Les polluants sont un ou plusieurs polluants choisis parmi les composés soufrés, le chlore, l'ammoniac, le mercure, l'arsenic, le cadmium ou leurs combinaisons.
