Ngaphambi kokusebenzisa ithangi lebitumen, inani elincane le-nitrogen eliwuketshezi kufanele lingeniswe ukuze liphole ngokushesha. Lapho izinga lokushisa ethangini lifinyelela izinga lokushisa le-nitrogen ewuketshezi, i-nitrogen ewuketshezi kufanele igcwaliswe ukuze ithangi lingagcwali. Amafilimu epulasitiki nezinye izinto zamakhemikhali azivunyelwe ukufakwa ngaphandle kwepulaki yentamo. Kusukela encane kuya enkulu, kuyoba inkathazo futhi ufundise ukusetshenziswa amathangi bitumen.

Amathangi e-bitumen kufanele aphathwe ngokucophelela ukuze agweme ukungqubuzana nokukhipha. Ungawadonsi emasimini uma uhamba, kodwa uwaphakamise kahle. Kufanele igcinwe endaweni eyomile futhi engenawo umoya phakathi nezinsuku ukuvimbela umswakama.

Ngoba amaphrojekthi amaningi okupholisa amanzi ajikelezayo ahlanganiswa ne-calcium, i-aluminium ion kanye nosawoti we-acidic kanye ne-alkaline. Lapho amanzi okupholisa egeleza endaweni yensimbi, kwakheka ama-sulfide. Ukwengeza, umoya-mpilo oncibilikisiwe emanzini apholisayo uzoqhubeka nokubangela ukugqwala kwe-electrochemical kanye nokuguqulwa kofuzo kokugqwala.

Ngenxa yokusabalala kokugqwala nesikali ethangini letiyela, umphumela wokudlulisa ukushisa uzinzile kodwa uyehla. Uma isikali sinzima, amanzi okupholisa azofafazwa ngaphandle kwebhokisi. Uma ukungcola kubi kakhulu, ipayipi lizovinjelwa, okwenza umsebenzi wokudlulisa ukushisa ungabi namsebenzi.

Ukunqwabelana kokungcola emathangini etiyela kuzodala umonakalo omkhulu ekuqhutshweni kokushisa, futhi ukwanda kwenetha ekuqongeleleni kuzobangela ukwanda kokusetshenziswa kwamandla. Ngisho nongqimba oluncane lokungcola luzokhuphula inani lokungcoliswa kwesisekeli libe ngaphezu kwamaphesenti angama-40 wokusebenza kwalo.

I-liquid ingakhishwa lapho ukucindezela ngaphakathi kwethangi lebitumen kufinyelela ezingeni futhi kufunwa ukukhishwa. Ukuze kuqinisekiswe ukuhlanzeka kwezinto ekusetshenzisweni kwesitoreji kanye nokunciphisa ukusetshenziswa koketshezi olubalulekile ngesikhathi sokugcwaliswa okulandelayo, amathangi okugcina akumele akhishwe ngokuphelele.
