Iinsimbi engagqwali Kuvunguza emoyeni duct yenziwe ngensimbi engagqwali.Izinto ezibonakalayo ziqinile, kulula ukugcina ubuqotho, ukubukeka okuhle, udonga lwangaphakathi olubushelelezi, ukumelana okuncane, ukuqina komoya okuhle, amandla okucindezela okukhulu, futhi kungafaneleka ubunjiniyela obuyinkimbinkimbi kakhulu.Ingaqeda amagesi alimazayo amakhemikhali avuthayo futhi angashi ngaphandle kwesidingo sokufaka imishini yokufafaza eyengeziwe.

Ngenxa yokumelana nokugqwala okuhle kakhulu, ukumelana nokushisa, amandla aphezulu nezinye izakhiwo ezingokomzimba namakhemikhali, isetshenziswa kabanzi ezinhlelweni ezihlukene zokukhipha umoya, izinhlelo zokukhipha i-solvent, izinhlelo ze-organic exhaust, izinhlelo zokukhipha umoya, izingxenye zangaphandle zesistimu yokukhipha umoya, amasistimu wokukhipha umoya omswakama nokushisa, izinhlelo zokususa intuthu nezintuli ezinezidingo zokuqina komoya okuphezulu.
