Ngokwendinganiso yesibabule ye-carburant, okuqukethwe kwesibabule se-carburant ngomqondo obanzi kungahlukaniswa kube isulfure ephezulu, isulfure ephakathi, isulfure ephansi, isulfure ephansi kakhulu.

Isibabule esiphezulu ngokuvamile sibhekisela kokuqukethwe kwesibabule ngaphezu kuka-2.0%

Isibabule esimaphakathi ngokuvamile sisho okuqukethwe kwesulfure okungu-1.0% - 2.0%

Isibabule esiphansi ngokuvamile sibhekisela ku-0.4% - 0.8% sulphur.

Isibabule esiphansi kakhulu ngokuvamile sibhekisela kokuqukethwe kwesibabule ngaphansi kuka-0.05%

Ukuhlukaniswa okujwayelekile kwesibabule kwama-carburants kubangelwa ikakhulukazi okuqukethwe kwesibabule okuhlukile kwe-residuum ezintweni zokusetshenziswa ezahlukene kanye nemingcele yokushisa yenqubo ehlukene yezinto zokusetshenziswa kwe-petroleum coke ekukhiqizeni nasekucubunguleni inqubo, okuholela kokuqukethwe kwesulfure okuhlukile kwe-carburants.

Kodwa-ke, ohlelweni lokusebenzisa i-carburizer ezimbonini ezihlukahlukene, umehluko omncane wokuqukethwe kwesibabule uzoba nomthelela omkhulu kumkhiqizo.Okubanzi kuphela ngokusho kwesulfure ephezulu, isulfure ephakathi, ukuhlukaniswa kwekhwalithi yesulfure ephansi ayiphelele, amazinga e-carburant sulfur angasetshenziswa kuphela njengereferensi yokukhethwa kwe-carburant.

Okungenhla kuphela ukuhlukaniswa okubanzi kwamazinga e-sulfur ejenti ye-carburizing, eqondile ekukhethweni kwe-ejenti yokungcwaba, okuqukethwe kwesibabule kuyinkomba ebaluleke kakhulu, kunconywa ukukhetha abakhiqizi abangochwepheshe.
