Inani elikhulu lentuthu ye-asphalt ehlakazekile ene-concentration ye-5-7mg/m~3 ikhiqizwa ngesikhathi sokukhiqizwa kwe-carbon workshop yesitshalo se-alumina.Uma ikhishwa ngokuqondile, izoba nomthelela omubi endaweni ezungezile kanye nabasebenzi basefekthri.Iqondiswe kulo msi, i-coke encane encibilikisiwe isetshenziselwa ukumunca nokuyihlanza, futhi i-coke egcwele amanzi ivuselelwa ngendlela yokukhiqiza kabusha okushisayo.

Okokuqala, inqubo ye-adsorption ye-coke e-calcined yafundwa, futhi imiphumela yokushisa kwe-adsorption, ukugxila kwe-pitch fume, isivinini sesikhala kanye nosayizi wezinhlayiyana ze-coke e-calcined kumphumela we-adsorption we-coke e-calcined kwahlaziywa.Imiphumela yocwaningo ikhombisa ukuthi inani lentuthu ekhalayo elikhangiswa i-coke ebaliwe liyakhula ngokukhula kokugxiliswa kwe-inlet ye-pitch fume.Isivinini sesikhala esiphansi, izinga lokushisa eliphansi, nosayizi wezinhlayiyana ezincane konke kunenzuzo ekukhanyisweni komusi we-pitch nge-coke calcined.I-adsorption thermodynamics ye-coke e-calcined yafundwa, eyabonisa ukuthi inqubo ye-adsorption yayiyi-adsorption ebonakalayo.Ukuhlehla kwe-adsorption isotherm kubonisa ukuthi inqubo ye-adsorption ihambisana nesibalo se-Langmuir.

Okwesibili, ukuvuselelwa kokushisisa kanye nokubuyiswa kwe-condensation kwe-coke e-calcined egcwele.Imiphumela yezinga lokugeleza kwegesi yenkampani, izinga lokushisa lokushisa, inani le-coke eligcwele eligcwele kanye nezikhathi zokukhiqiza kabusha ekusebenzeni kahle kokuvuselelwa kwe-coke e-calcined kuye kwaphenywa ngokulandelana.Imiphumela yokuhlola ibonisa ukuthi lapho izinga lokugeleza kwegesi yenkampani yenethiwekhi likhuphuka, izinga lokushisa lokushisisa liyakhuphuka, kanye nenani le-coke ngemva kokuncipha kwe-saturated calcining, kunenzuzo ekuthuthukiseni ukusebenza kahle kokuvuselela.Hlanganisa futhi umunce igesi yomsila wokuvuselela, futhi izinga lokubuyisela lingaphezu kwama-97%, okubonisa ukuthi indlela yokufingqa nokumunca ingakwazi ukubuyisela itiyela kugesi yomsila wokuvuselela kahle.

Ekugcineni, izinhlelo ezintathu zokuqoqwa kwegesi, ukuhlanzwa kanye nokuvuselelwa kabusha ziyaklanywa, futhi imiphumela yokuklama iyasetshenziswa.Imiphumela yokusetshenziswa kwezimboni ibonisa ukuthi ukusebenza kahle kokuhlanzeka kwe-asphalt fume ne-benzo(a)pyrene kufinyelela ku-85.2% no-88.64%, ngokulandelana, lapho isihlanzi sisetshenziswa ukuze sibambe futhi sihlanze intuthu yetiyela ehlakazekile nengahlelekile.Ukugxiliswa kwentuthu ye-asphalt ne-benzo(a)pyrene lapho kuphuma khona okokuhlanza kube ngu-1.4mg/m~3 kanye no-0.0188μg/m~3, futhi ukukhishwa kube ngu-0.04kg/h kanye no-0.57×10~(-6)kg /h, ngokulandelana.Ifinyelele izinga lesibili lokukhishwa okuphelele kokungcola komoya GB16297-1996.
