Title (EN) SYSTEMS AND METHODS FOR REMOVAL OF MERCURY AND/OR HYDROCHLORIC ACID FROM GAS STREAMS USING CALCIUM-CONTAINING PARTICLES
(FR) SYSTÈMES ET PROCÉDÉS D'ÉLIMINATION DU MERCURE OU DE L'ACIDE CHLORHYDRIQUE À PARTIR DE FLUX GAZEUX À L'AIDE DE PARTICULES CONTENANT DU CALCIUM
Abstract:
(EN) Several embodiments of the present technology are directed to the removal of one or more air pollutants using cooling and/or calcium-containing particles. In some embodiments, a method for removing air pollutants comprises flowing a gas stream having calcium-containing particles and one or more of mercury or hydrochloric acid molecules, and cooling the gas stream, thereby causing at least a portion of the calcium-containing particles to adsorb to the mercury and/or hydrochloric acid molecules in the gas stream. The method can further comprise, after cooling the gas stream, filtering the gas stream to remove at least a portion of the calcium-containing particles having adsorbed mercury and hydrochloric acid.
(FR) Plusieurs modes de réalisation de la présente technologie concernent l'élimination d'un ou de plusieurs polluants de l'air à l'aide d'un refroidissement ou de particules contenant du calcium. Dans certains modes de réalisation, un procédé d'élimination de polluants de l'air comprend l'écoulement d'un flux gazeux renfermant des particules contenant du calcium et une ou plusieurs molécules de mercure ou d'acide chlorhydrique, et le refroidissement du flux gazeux, ce qui amène au moins une partie des particules contenant du calcium à s'adsorber sur les molécules de mercure ou d'acide chlorhydrique dans le flux gazeux. Le procédé peut en outre comprendre, après refroidissement du flux gazeux, le filtrage du flux gazeux afin d'éliminer au moins une partie des particules contenant du calcium ayant adsorbé du mercure et de l'acide chlorhydrique.
