Inkqubo yokubuyisa igesi ephumayo sisixhobo sokukhusela okusingqongileyo esijolise ekunciphiseni ukukhutshwa kwegesi okuyingozi okubangelwa yimveliso yemizi-mveliso kunye neminye imisebenzi. Ngokubuyisela nokunyanga ezi gesi ziphumayo, ayikhuseli okusingqongileyo kuphela kodwa ikwafezekisa ukuphinda kusetyenziswe izixhobo. Olu hlobo lweenkqubo lubaluleke kakhulu kumashishini afana neekhemikhali, ukucocwa kwepetroli, amayeza, kunye nokulungiswa kokutya, njengoko zinceda iinkampani ukuba zihlangabezane nemigangatho yokusingqongileyo ngelixa ziphucula ukusebenza kwamandla kunye nezixhobo. Eli linqaku lilandelayo elinamagama angama-500 malunga neenkqubo zokubuyisa igesi eziphumayo:

Kwiinkqubo zemveliso yemizi-mveliso yanamhlanje, ukukhutshwa komoya ongcolileyo yingxaki engenakuphepheka. Ezi gesi zomoya ongcolileyo aziqulathi nje kuphela izinto eziyingozi ezibangela ungcoliseko kwindalo esingqongileyo, kodwa zinokuba neekhemikhali kunye namandla angasetyenziswa kwakhona, kwaye ukukhutshwa kwazo ngokuthe ngqo akupheleli nje ekulahlekeni kwezixhobo kodwa konakalisa nendalo. Ke ngoko, inkqubo yokubuyisela igesi yomoya ongcolileyo ibe yindlela esebenzayo yokusombulula le ngxaki. Ngokuqokelela, ukucoca, kunye nokuphinda usebenzise iigesi zomoya ongcolileyo, ungcoliseko lwendalo lunokunciphisa kwaye ukusetyenziswa kwezixhobo kunokuphuculwa, nto leyo ebaluleke kakhulu ekufezekiseni uphuhliso oluzinzileyo lwemveliso yemizi-mveliso.

Umgaqo osebenzayo wenkqubo yokubuyisa igesi ephumayo udla ngokuquka amanyathelo aliqela aphambili: ukuqokelelwa kwegesi ephumayo, unyango kunye nokucocwa kwegesi ephumayo, kunye nokurisayikilisha kunye nokusetyenziswa. Okokuqala, igesi ephumayo evelisiweyo iqokelelwa ngenkqubo yokuqokelela, emva koko ngothotho lweenkqubo zonyango kunye nokucoca, izinto ezinobungozi kwigesi ephumayo ziyasuswa, kwaye iikhemikhali okanye amandla axabisekileyo ayafunyanwa. Okokugqibela, igesi ecutshungulwayo kufuneka ikhutshwe ngokukhuselekileyo okanye isetyenziswe kwakhona.

Iinkalo zokusetyenziswa kweenkqubo zokubuyisa igesi ephumayo zibanzi, kwaye amashishini ahlukeneyo kunye neenkqubo zemveliso zifuna ukusetyenziswa kweteknoloji ezahlukeneyo zokubuyisa. Umzekelo, kwishishini le-petrochemical, izinyibilikisi zezinto eziphilayo kunye nezinto ze-hydrocarbon kwiigesi eziphumayo zinokufunyanwa ngeendlela ezifana nokufunxwa, ukufunxwa, kunye nokufuma; Ekuveliseni umbane kunye namandla obushushu, ukukhutshwa kwe-sulfur dioxide kunye ne-nitrogen oxides kunokuncitshiswa ngetekhnoloji yokususa i-flue gas desulfurization kunye ne-denitrification; Kwishishini lokucubungula ukutya kunye namayeza, umphunga we-organic kunye notywala obuvela kwiigesi eziphumayo zinokufunyanwa ukuze zisetyenziswe kwezinye iinkqubo zemveliso.

Inkqubo yokubuyisa igesi ephumayo ayincedi nje kuphela amashishini ukunciphisa iindleko zokusebenza nokuphucula ukusebenza kakuhle kwezoqoqosho, kodwa ikwadlala indima entle ekukhuseleni okusingqongileyo. Ukunciphisa ukukhutshwa kweegesi eziyingozi nokunciphisa ungcoliseko emoyeni nakwindalo esingqongileyo yoMhlaba kunokunceda ukuphucula umgangatho womoya nokukhusela impilo yabantu. Kwangaxeshanye, uphuhliso kunye nokusetyenziswa kwetekhnoloji yokubuyisa igesi ephumayo kukwakhuthaze inkqubela phambili kwetekhnoloji yokukhusela okusingqongileyo kunye nobuchule ekulawuleni okusingqongileyo.

Ngamafutshane, iinkqubo zokubuyisa igesi ephumayo zizixhobo ezibalulekileyo zokufezekisa imveliso yemizi-mveliso enobuhlobo nokusingqongileyo kunye nokusetyenziswa kwezixhobo ngokufanelekileyo. Ngenxa yemithetho yokusingqongileyo engqongqo ngakumbi kunye nokuphuculwa kolwazi loluntu ngokusingqongileyo, iteknoloji yokubuyisa igesi ephumayo iya kusetyenziswa kwaye iphuhliswe ngokubanzi, ibe yinkxaso ephambili yokukhuthaza ukuphunyezwa kwezicwangciso zophuhliso oluzinzileyo.
