Uhlelo lokubuyisela igesi ephumayo luyithuluzi lokuvikela imvelo okuhloswe ngalo ukunciphisa ukukhishwa kwegesi eyingozi ekhiqizwa ekukhiqizeni kwezimboni neminye imisebenzi. Ngokuthola nokwelapha la magesi akhipha umoya, akugcini nje ukuvikela indawo ezungezile kodwa futhi kuzuzisa ukusetshenziswa kabusha kwezinsiza. Lezi zinhlobo zezinhlelo zibaluleke kakhulu ezimbonini ezifana namakhemikhali, ukuhluzwa kwe-petroleum, ezemithi, nokucubungula ukudla, njengoba zisiza izinkampani ukuthi zihlangabezane namazinga emvelo kuyilapho zithuthukisa ukusebenza kahle kwamandla nezinto ezibonakalayo. Okulandelayo yi-athikili yamagama angu-500 mayelana nezinhlelo zokubuyisela igesi exhaust:

Ezinqubweni zokukhiqiza zezimboni zesimanje, ukukhishwa kwe-exhaust kuyinkinga engenakugwemeka. Lawa magesi akhipha imfucumfucu awagcini nje ngokuqukatha izinto eziyingozi ezidala ukungcoliswa kwemvelo, kodwa angase futhi aqukathe amakhemikhali asebenziseka kabusha namandla, futhi ukukhishwa kwawo okuqondile akugcini nje ngokumosha izinsiza kodwa futhi kulimaza imvelo. Ngakho-ke, uhlelo lokubuyisela igesi exhaust luye lwaba yindlela ephumelelayo yokuxazulula le nkinga. Ngokuqoqa, ukuhlanza, kanye nokugaywa kabusha kwamagesi akhipha umoya, ukungcoliswa kwemvelo kungancishiswa futhi ukusetshenziswa kwezinsiza kungathuthukiswa, okuyisinyathelo esibalulekile sokuzuza intuthuko esimeme yokukhiqizwa kwezimboni.

Umgomo wokusebenza wesistimu yokukhipha igesi ephumayo ngokuvamile uhlanganisa izinyathelo ezimbalwa ezibalulekile: ukuqoqwa kwegesi ekhishwayo, ukwelashwa kanye nokuhlanzwa kwegesi ekhishwayo, kanye nokugaywa kabusha nokusetshenziswa. Okokuqala, igesi yokukhipha igesi ekhiqiziwe iqoqwa ngohlelo lokuqoqwa, bese kuthi ngochungechunge lwezinqubo zokwelapha nokuhlanza, izingxenye eziyingozi kugesi wokuphuma ziyasuswa, futhi amakhemikhali abalulekile noma amandla atholakala. Okokugcina, igesi ecutshunguliwe kufanele ikhishwe ngokuphepha noma igaywe kabusha.

Izinkambu zokufaka izicelo zezinhlelo zokubuyisela igesi exhaust zibanzi, futhi izimboni ezihlukene nezinqubo zokukhiqiza zidinga ukusetshenziswa kobuchwepheshe obuhlukene bokubuyisela. Isibonelo, embonini ye-petrochemical, izinyibilikisi ze-organic kanye nezinto ze-hydrocarbon kumagesi aphumayo zingatholwa ngezindlela ezinjengokumunca, ukukhanyiswa, nokufingqa; Ekukhiqizeni ugesi namandla ashisayo, ukukhishwa kwe-sulfur dioxide kanye ne-nitrogen oxides kungancishiswa ngokusebenzisa i-flue gas desulfurization kanye nobuchwepheshe be-denitrification; Embonini yokucubungula ukudla kanye nemithi, ama-organic vapors kanye notshwala obuphuma kumagesi aphumayo kungabuyiswa ukuze kusetshenziswe kwezinye izinqubo zokukhiqiza.

Uhlelo lokubuyisela igesi exhaust alusizi nje kuphela amabhizinisi ukunciphisa izindleko zokusebenza nokuthuthukisa ukusebenza kahle komnotho, kodwa futhi ludlala indima enhle ekuvikelweni kwemvelo. Ukunciphisa ukukhishwa kwamagesi ayingozi kanye nokunciphisa ukungcoliswa komkhathi kanye nendawo ezungezile yoMhlaba kungasiza ukuthuthukisa izinga lomoya futhi kuvikelwe impilo yabantu. Ngesikhathi esifanayo, ukuthuthukiswa kanye nokusetshenziswa kobuchwepheshe bokubuyisela igesi ephumayo nakho kukhuthaze inqubekelaphambili yobuchwepheshe bokuvikela imvelo kanye nokusha ekuphathweni kwemvelo.

Ngamafuphi, amasistimu okubuyisela igesi ephumayo angamathuluzi abalulekile okuzuza ukukhiqizwa kwezimboni okungenabungani kwemvelo kanye nokusetshenziswa kwezinsiza ngendlela efanele. Ngokukhula kwemithetho eqinile yezemvelo kanye nokuthuthukiswa kokuqwashisa umphakathi ngemvelo, ubuchwepheshe bokubuyisela igesi exhaust buzosetshenziswa kabanzi futhi buthuthukiswe, bube ukusekelwa okubalulekile ekukhuthazeni ukuqaliswa kwamasu okuthuthukiswa okusimeme.
