Inkqubo yokubuyisela i-gas exhaust sisixhobo sokukhusela indalo esijolise ekunciphiseni ukukhutshwa kwegesi eyingozi eyenziwa kwimveliso yoshishino kunye neminye imisebenzi. Ngokufumana kwakhona kunye nokunyanga ezi gesi eziphumayo, akukhuseli okusingqongileyo kuphela kodwa kukwafezekisa ukusetyenziswa kwakhona kobutyebi. Ezi ntlobo zeenkqubo zibaluleke kakhulu kumashishini afana neekhemikhali, ukucocwa kwepetroleum, amayeza, kunye nokulungiswa kokutya, njengoko zinceda iinkampani ukuba zihlangabezane nemigangatho yokusingqongileyo ngelixa ziphucula amandla kunye nokusebenza kakuhle kwezinto. Oku kulandelayo linqaku le-500 malunga neenkqubo zokubuyisela igesi ephumayo:

Kwiinkqubo zemveliso yanamhlanje, ukukhutshwa kombhobho kuyingxaki engenakuphepheka. Ezi gesi zombhobho aziqulathanga kuphela izinto eziyingozi ezibangela ungcoliseko kokusingqongileyo, kodwa zisenokuqulatha iikhemikhali ezinokurisayiklishwa kunye namandla, kwaye ukukhutshwa kwazo ngokuthe ngqo akukona nje ukumosha imithombo kodwa nako konakalisa i-ikholoji. Ngoko ke, inkqubo yokubuyisela igesi yokukhupha ibe yindlela efanelekileyo yokusombulula le ngxaki. Ngokuqokelela, ukucocwa, kunye nokuphinda kusetyenziswe iigesi zokukhupha, ukungcoliseka kwendalo kunokuncitshiswa kunye nokusetyenziswa kwezixhobo kungaphuculwa, okuyindlela ebalulekileyo yokuphumeza uphuhliso oluzinzileyo lwemveliso yemizi-mveliso.

Umgaqo wokusebenza wenkqubo yokubuyisela igesi ephumayo ngokuqhelekileyo ubandakanya amanyathelo amaninzi aphambili: ukuqokelela igesi yokukhupha, unyango kunye nokucocwa kwegesi yokukhupha, kunye nokuphinda kusetyenziswe kunye nokusetyenziswa. Okokuqala, igesi ephumayo ephumayo iqokelelwa ngenkqubo yokuqokelela, kwaye emva koko ngoluhlu lweenkqubo zonyango kunye nokuhlanjululwa, amacandelo ayingozi kwi-gas yokukhupha ayasuswa, kwaye iikhemikhali ezixabisekileyo okanye amandla afunyanwa. Ekugqibeleni, igesi esetyenzisiweyo kufuneka ikhutshwe ngokukhuselekileyo okanye isetyenziswe kwakhona.

Iinkalo zokusetyenziswa kweenkqubo zokubuyisela igesi yokukhupha zibanzi, kwaye amashishini ahlukeneyo kunye neenkqubo zokuvelisa zifuna ukusetyenziswa kobugcisa obuhlukeneyo bokubuyisela. Ngokomzekelo, kwishishini le-petrochemical, i-solvents ye-organic kunye ne-hydrocarbon substances kwi-exhaust gases inokubuyiselwa ngeendlela ezifana nokuxutywa, i-adsorption, kunye ne-condensation; Kwimveliso yombane kunye ne-thermal energy, ukukhutshwa kwe-sulfure dioxide kunye ne-nitrogen oxides kunokuncitshiswa nge-flue gas desulfurization kunye ne-denitrification technology; Kwimizi-mveliso yokutya kunye namayeza, umphunga we-organic kunye notywala obuvela kwi-exhaust gases inokubuyiselwa ukuze isetyenziswe kwezinye iinkqubo zokuvelisa.

Inkqubo yokubuyisela igesi yokukhupha ayincedi kuphela amashishini ukunciphisa iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle kwezoqoqosho, kodwa idlala indima enhle ekukhuselweni kwendalo. Ukunciphisa ukukhutshwa kweegesi eziyingozi kunye nokunciphisa ungcoliseko kwi-atmosfera kunye nokusingqongileyo koMhlaba kunganceda ukuphucula umgangatho womoya kunye nokukhusela impilo yabantu. Ngelo xesha, uphuhliso kunye nokusetyenziswa kweteknoloji yokubuyisela igesi ephumayo nayo ikhuthaze inkqubela phambili yeteknoloji yokukhusela indalo kunye nokutsha kulawulo lokusingqongileyo.

Ngamafutshane, iinkqubo zokubuyisela igesi ephumayo zizixhobo ezibalulekileyo zokuphumeza imveliso yemizi-mveliso ehambelana nokusingqongileyo kunye nokusetyenziswa kobutyebi ngokufanelekileyo. Ngokunyuka kwemimiselo engqongqo yokusingqongileyo kunye nokuphuculwa kolwazi lokusingqongileyo kuluntu, iteknoloji yokubuyisela igesi yokukhupha igesi iya kusetyenziswa ngokubanzi kwaye iphuhliswe, ibe yinkxaso ephambili yokukhuthaza ukuphunyezwa kwezicwangciso zophuhliso oluzinzileyo.
