Ngophuhliso olukhawulezayo lolwakhiwo lohola wendlela kunye nokwanda kwemfuno yebhitumene, ibhitumene enemivalo isetyenziswa kakhulu ngenxa yokuthuthwa kwayo umgama omde kunye nokugcinwa ngokulula. Ngokukodwa, uninzi lwebhitumene ekumgangatho ophezulu esetyenziswa kumazwe angaphandle esetyenziswa kwiindlela ezinesantya esiphezulu ikwimo yombhobho. Esi Sityalo sokunyibilikisa ibhitumene esinyibilika ngokukhawuleza, sisuse imiphanda ngokucocekileyo, kwaye sithintele ibhitumene ekugugeni iyafuneka.

Isixhobo sokunyibilikisa ibhitumene esiveliswe yinkampani yethu ikakhulu siquka ibhokisi yokususa imiphanda, ucango lokunyuswa kombane, itroli yokulayisha ibhitumene, inkqubo yokuqhuba itroli, inkqubo yokufudumeza ioyile, inkqubo yokufudumeza ioyile yokufudumeza igesi, impompo yebhitumene kunye nenkqubo yepayipi yombane. inkqubo yokulawula kunye namanye amalungu.

Ibhokisi ihlulwe ngamagumbi aphezulu nangaphantsi. Igumbi eliphezulu ligumbi lokukhupha umphanda kunye negumbi lokunyibilikisa ibhitumene enombhobho. Umbhobho wokufudumeza i-oyile ezantsi kunye ne-high-temperature flue gas esuka kwibhoyila yeoli ye-thermal ngokudibeneyo ukutshisa i-bitumen barrel ukufezekisa injongo yokukhupha i-bitumen. Igumbi elingaphantsi lisetyenziselwa ukuqhubeka nokutshisa i-bitumen ekhutshwe kwi-barrel. Emva kokuba ubushushu bufikelele kwiqondo lokumpompa (ngaphezu kwe-110 ° C), impompo ye-asphalt inokuqaliswa ukumpompa ibhitumene. Kwinkqubo yemibhobho yebhitumene, isihluzi sifakwe ukuze sisuse ngokuzenzekelayo i-slag inclusions kwibhitumene enemivalo.

Izixhobo zomatshini wokunyibilikisa ibhitumene zixhotyiswe ngokulinganayo kwimingxunya engqukuva yokumisa ibhakethi ukuququzelela ukuma okuchanekileyo kwebhakethi nganye xa kulayishwa. Inkqubo yokuhambisa inoxanduva lokulayisha kunye nokukhulula imigqomo enzima egcwele ibhitumene kunye nemigqomo engenanto emva kokucoca ngaphakathi nangaphandle kwegumbi eliphezulu lebhokisi. Inkqubo yokusebenza yezixhobo igqitywe ngokusebenza okuphakathi kwikhabhinethi yokulawula umbane, kwaye ixhotyiswe ngezixhobo ezifunekayo zokubeka iliso kunye nezixhobo zokulawula ukhuseleko.
