Njengamanje, ingcindezi yokuvikela imvelo yesitshalo esijikelezayo sokwenza insimbi yesithando somlilo inkulu. Phakathi kwazo, uhlelo lokususa uthuli lwegesi yomlilo ojikelezayo luyinto ebaluleke kakhulu, futhi kuyadingeka ukusebenzisa ukuguqulwa okuhlanzekile ukuze kuzuzwe ukukhishwa kwe-ultra-low. Ngakho-ke, ukukhethwa kanye nokusetshenziswa kobuchwepheshe bokukhipha isithando esijikelezayo esisebenza kahle, esiphephile nesisetshenziswa kancane sekuyisihloko esiphuthumayo samabhizinisi ensimbi nensimbi.
Indlela emanzi kanye nendlela eyomile yokukhishwa kwegesi yesithando somlilo esithandweni sinezinzuzo zabo siqu
Ubuchwepheshe bokukhipha i-furnace obumanzi bufushaniswa njenge-OG. I-OG isifinyezo se-Oxygen rotating furnace Gas Recovery ngesiNgisi, okusho ukubuyiswa kwegesi yesithando somlilo esizungezayo. Isithando somlilo esijikelezayo sisebenzisa ubuchwepheshe be-OG sikhiqiza inani elikhulu lokushisa eliphezulu kanye ne-high-concentration ye-CO flue gas esithandweni ngenxa yokusabela kwe-oxidation enobudlova ngesikhathi sokufutha. I-flue gas icindezela ukungena komoya ozungezile ngokuphakamisa isiketi kanye nokulawula ukucindezela kwegesi eshisayo ngaphakathi kwehood. Endabeni yokungashiswa, ubuchwepheshe buthatha i-vaporization cooling flue ukuze ipholise igesi ye-flue, futhi ngemva kokuhlanzwa yi-Venturi tube collector yezigaba ezimbili, ingena ohlelweni lokubuyisela nokukhulula igesi.
Ubuchwepheshe obujikelezayo bokukhipha uthuli lwesithando somlilo esishisayo bufushaniswa njengeLT. ILTIndlela yasungulwa ngokuhlanganyela uLurgi noThyssen eJalimane.LTisifinyezo samagama ezinkampani ezimbili. Lobu buchwepheshe busebenzisa i-coolerization vaporization ukupholisa igesi ephumayo, futhi ngemva kokuhlanzwa nge-cylindrical dry electrostatic precipitator, bungena ohlelweni lokubuyisela nokukhulula igesi. Lo mthetho waqala ukusetshenziswa kumaphrojekthi wokubuyisela igesi ngo-1981.
Ubuchwepheshe bokukhipha isithando somlilo obujikelezayo bunotshalomali olukhulu lwesikhathi esisodwa, isakhiwo esiyinkimbinkimbi, izinto eziningi ezisebenzisekayo, nobunzima obuphezulu bezobuchwepheshe. Izinga lokukhushulwa kwemakethe ezweni lami lingaphansi kwama-20%. Ngaphezu kwalokho, ubuchwepheshe bokukhipha uthuli olomile busebenzisa i-electrostatic precipitator enkulu eyomile ukususa uthuli lwesithando somlilo esijikelezayo se-viscous. Umqoqi wothuli kulula ukuqongelela uthuli futhi ukukhishwa kothuli akuzinzile.
Uma kuqhathaniswa nenqubo yokususa uthuli olomile, inqubo ye-OG yokususa uthuli olumanzi inesakhiwo esilula, izindleko eziphansi, nokusebenza kahle kokuhlanza okuphezulu, kodwa inezinkinga ezifana nokusetshenziswa kwamandla aphezulu, ukusetshenziswa kwamanzi okukhulu, ukuthuthwa kwendle okuyinkimbinkimbi, nezindleko eziphezulu zokusebenza. Ngaphezu kwalokho, ubuchwepheshe bokukhipha uthuli olumanzi bugeza lonke uthuli emanzini kungakhathaliseki ukuthi izinhlayiya zingakanani, okuholela ekutheni kube nenani elikhulu lokuthuthwa kwendle. Nakuba izinga lobuchwepheshe lezinqubo zokukhipha imfucumfucu ezomile nezimanzi liye lathuthukiswa ngokuqhubekayo enqubweni yokwenziwa kwendawo, amaphutha azo akhona awakaxazululwa.
Ukuphendula lesi simo esingenhla, ochwepheshe bezimboni bahlongoza ubuchwepheshe bokususa uthuli oluyomile eminyakeni yamuva, obuthuthukiswe eChina. Njengamanje, inani leziko elizungezayo lisebenzisa ubuchwepheshe bokukhipha i-semi-dry lidlula inani leziko elizungezayo lisebenzisa ubuchwepheshe bokukhipha udoti okomile. Inqubo yokukhipha i-semi-dry isebenzisa isipholile esomile esihwamukayo ukuze sibuyise u-20% -25% womlotha owomile, ogcina izinzuzo zokukhipha imfucumfucu emanzi futhi enqobe ububi bobuchwepheshe bokukhipha imfucumfucu obumanzi nobumanzi. Ikakhulukazi, lobu buchwepheshe bungaguqula inqubo yokukhipha amanzi emanzi ngaphandle kokuyihlakaza ngokuphelele futhi iphinde yenziwe kabusha njengenqubo yokukhipha okomile, ukuze izinsiza zangempela zigcinwe ngokwezinga elikhulu futhi kusindiswe izindleko zokutshala imali.
