Iyunithi ye-desulfurization sisixhobo soshishino esisetyenziselwa ukususa i-sulphur kwimathiriyeli ekrwada, esetyenziswa ngokubanzi kwi-flue gas desulfurization kwizityalo zamandla ezibaswayo ngamalahle, ii-kilns, kunye negesi yomsila wekhemikhali. Umgaqo wayo wokusebenza ubandakanya ukusabela kwe-alkaline desulfurizing agent (efana ne-limestone okanye i-magnesium oxide) kunye ne-sulfur dioxide kwi-gas flue, ukuvelisa i-byproducts efana ne-calcium sulfate okanye i-magnesium sulfate. Esi sixhobo sibonisa ukusebenza kakuhle kwe-desulfurization, itekhnoloji evuthiweyo, kunye nokusebenza okuthembekileyo kunye nokuzinza.
Iyunithi ye-desulfurization isebenzisa i-alkaline desulfurizing agent ukuze isabele ngokwekhemikhali ngesulfure{0}equlathe imathiriyeli ekrwada (efana ne-sulphur dioxide kwigesi yomkhuhlane), ivelisa izinto eziphuma ngaphandle ezifana ne-sulfates. Ngokuqhelekileyo zisetyenziselwa i-desulfurizing agents ziquka i-limestone kunye ne-magnesium oxide. Itekhnoloji ye-Magnesium oxide desulfurization ineenzuzo ekunyangeni irhasi ye-flue evela kwizityalo zamandla ashushu kunye ne-steelmaking blast furnaces, kwaye ifanelekile ngakumbi kwiindawo ezityebileyo kwi-magnesium oxide.
