Embonini yamakhemikhali nakweminye imikhakha eminingi yokukhiqiza, ukuxuba nokunyakazisa izinto zokusetshenziswa ezihlukene ngezilinganiso ezifanele kuyinqubo evamile. Isibonelo, ekukhiqizeni ingcina, i-resin, i-hardener, nezinye izinto zokusetshenziswa eziyimpushana zifakwa ku-reactor bese zinyakaziswa ukuze kwakhiwe ingcina ngokusabela kwamakhemikhali. Kodwa-ke, phakathi nenqubo yokuxuba nokunyakazisa, umoya ungangena ku-slurry, okwenza ama-bubbles akhe ngaphakathi kwempahla eluhlaza. Lawa mabhamuza angathinta izinyathelo zokucubungula ezilandelayo futhi ehlise ikhwalithi yomkhiqizo. Ukuze ususe ama-bubbles ezintweni ezingavuthiwe, amaphampu we-vacuum kanyeizihlukanisi zegesi-uketsheziziyimishini ebalulekile.
Inqubo ye-vacuum degassing isusa amabhamuza ku-slurry ngokudala indawo ye-vacuum. Ngokukhethekile, iphampu yevacuum isetshenziselwa ukukhipha indawo yokusebenza iye endaweni ye-vacuum, kusetshenziswa umehluko wengcindezi ukuze kukhishwe amabhamuza ngaphakathi kodaka. Lokhu akuthuthukisi nje kuphela ikhwalithi yezinto ezingavuthiwe kodwa futhi kuthuthukisa inqubo yokukhiqiza. Kodwa-ke, uma usebenzisa ipompo ye-vacuum, isihlukanisi se-vacuum gas-liquid siyadingeka futhi. Lesi sihlukanisi sivimbela udaka ekungeneni empompini yevacuum ngesikhathi senqubo yokuphuma futhi ngokunamandla okuyonakalisa.
Isihlukanisi se-gas-liquid idivayisi eklanywe ngokukhethekile esetshenziselwa ukuhlukanisa igesi noketshezi kwingxube ye-gas-liquid. Ngesikhathi senqubo yokukhipha i-vacuum, ipompo ye-vacuum ingase idwebe okunye okudaka ngesikhathi senqubo yokukhipha. Uma i-slurry ingena empompini ye-vacuum, ingalimaza okokusebenza futhi ithinte ukusebenza kahle kokukhiqiza. Ngemva kokufaka i-isihlukanisi segesi-uketshezi, opharetha kufanele njalo bahlole futhi banakekele okokusebenza ukuze baqinisekise ukusebenza okufanele. Ukusetshenziswa ngendlela efanele kanye nokugcinwa kahle kwesihlungi sepompo ye-vacuum kunganweba impilo yepompo ye-vacuum futhi kuthuthukise ukusebenza kahle okuphelele kwenqubo yokususa umoya we-vacuum.
Ngaphandle kwemboni yamakhemikhali, ezinye izimboni ezidinga ukuxutshwa kwezinto ezingavuthiwe nazo zingasebenzisa i-vacuum degassing. Isibonelo, ukucubungula ukudla, ukukhiqizwa kwemithi, kanye nokukhiqizwa kwezinto zikagesi konke kudinga ukusetshenziswa kwamaphampu evacuum kanyeizihlukanisi zegesi-uketsheziukususa amagwebu ezintweni ezingavuthiwe nokuqinisekisa ikhwalithi yomkhiqizo.
