Abstract (en)
[origin: WO2020216837A1] The invention relates to a method for cleaning corrosive process gases that contain sulfur compounds. According to the method, a gas stream that contains corrosive gases is conducted, in a sorption phase, over an inorganic sorbent material which absorbs at least one of the sorbable sulfurous components on the sorbent material, and the sulfurous compound-depleted gas stream is removed.
