Njengophethiloli obalulekile ohlanzekile kanye nokuqukethwe okuluhlaza kwamakhemikhali, i-lignite isetshenziswa kabanzi emkhakheni wensimbi, amakhemikhali, ugesi nakweminye imikhakha. Ngemuva kweminyaka yokwenza kahle kwezobuchwepheshe, inqubo yayo yokukhiqiza yakha uhlelo oluhlelekile nolumele lwemvelo. Ukuqonda inqubo yokukhiqiza yeLignite kuzosiza izinkampani zezohwebo zangaphandle ukuba ziqonde izici zomkhiqizo zinembe kakhudlwana futhi zihlangabezane nezidingo zemakethe yamazwe omhlaba.
Izinto ezivuthiwe zokukhiqizwa kwe-lignite ikakhulukazi ziphansi - njenge-lignite kanye ne-flame coal ende. Inqubo yokukhiqiza ihlukaniswe izigaba ezine eziyinhloko: Ukulungiswa okubonakalayo okuluhlaza, ukugcotshwa komile, ukupholisa nokusebenza komkhiqizo okuqediwe. Okokuqala, amalahle eluhlaza adinga ukuhlolwa futhi achotshozwe ukususa ukungcola nokulawula usayizi wezinhlayiyana ukuze kuqinisekiswe ukusebenza okuzinzile kwenqubo elandelayo elomile. Amalahle aqhekekile angena esithandweni sokomile sakwa-distillation futhi ama-pyrolyzed emazingeni okushisa aphakathi nendawo aphansi ngaphansi kokuhlukaniswa komoya. Amazinga okushisa asomile ahlala alawulwa phakathi kwama-550℃kanye ne-800 degree. Kulesi sigaba, into eshintshashintshayo kumalahle iyabhekelwa kancane kancane ukwakha imikhiqizo efana ne-lignite, i-coal tar kanye negesi yokungcola.
Ngemuva kokuthi i-distillation eyomile isiqediwe, i-lignite idinga ukuphola ngokushesha ukugwema i-oxidation. Inqubo yendabuko isebenzisa ukupholisa kwamanzi, kodwa ukuze kuncishiswe ukusetshenziswa kwamanzi, ezinye izinkampani ziye zamukela ubuchwepheshe bokujikeleza kawoyela okupholile noma ukudlulisa amafutha okuvuselela amafutha, okungagcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi kunciphisa nomthelela wezemvelo. Ngemuva kokupholisa, i-semi - coke ingena esiteji sokuhlola nokupakisha, ilungisa usayizi wezinhlayiyana ngokuya ngezidingo zamakhasimende, futhi iqedele ukufakwa okujwayelekile ngemishini yokupakisha ezenzakalelayo yokuhamba okulula nokugcinwa.
Ngokwephuculwa kwezidingo zokuvikelwa kwemvelo, i-semi - Inqubo yokukhiqiza iCoke nayo iyathuthuka ngokuqhubekayo. Isibonelo, ngokwenza kahle ukwakheka kwesithando somlilo se-retort, ukusebenza kahle okushisayo kungathuthukiswa futhi ukuphuma kwegesi okuqedayo kungancishiswa; Ukuvuselelwa kabusha kwe-coal tal kanye negesi yemfucuza kuphinde kwandisa inani elingeziwe lezinsizakusebenza. Lezi zinqubekelaphambili zezobuchwepheshe zenza i-semi - coke ukuncintisana ngokwengeziwe emakethe yamazwe omhlaba futhi ibe yikhwalithi ephezulu - enye indlela yekhwalithi yamalahle endabuko.
Ukuvuthwa kanye nokwenziwa okusha kwe-semi - inqubo yokukhiqiza iCoke ayigcini nje ngokuhlangabezana nezidingo zoguquko lwamandla ekhaya nakwamanye amazwe, kepha futhi ihlinzeka ngeziqinisekiso zomkhiqizo ezithembekile zamabhizinisi okuhweba kwangaphandle. Ngokuzayo, ngohlelo lokusebenza lwe- - ubuchwepheshe obuluhlaza obuluhlaza, imboni ye-semi - i-coke izothumela endaweni ebanzi yokuthuthuka.
