Emhlabeni ophakade wokuchaza uPetroleum, isidingo samafutha asezingeni eliphakeme kanye nama-distillates aphezulu kakhulu. Njengoba ama-combreries alwela ukufeza imithethonqubo eqinile yemvelo kanye nokulindelwe kwabathengi, indima ye-hydrotreating carlysts isiyanda kakhulu. Ama-catalysts ethu we-serial hydrotreating aklanyelwe ukuthuthukisa izinqubo zokucwecwa, ukuqinisekisa ukuthi ama-distillates ahlukahlukene ahlangabezana nezincazelo ezidingekayo zekhwalithi nokusebenza.

I-Hydrotreating inqubo ebalulekile ekuconyweni okuhilela okubandakanya ukususwa kokungcola okufana nesibabule, i-nitrogen, kanye nama-aromatics kusuka kumafutha oil ongahluziwe. Le nqubo ayigcini nje ngokuthuthukisa ikhwalithi yemikhiqizo yokugcina kodwa futhi isiza ngokuhambisana nemithetho yezemvelo okuhloswe ngayo ukunciphisa ukuphuma okulimazayo. Ama-catalysts ethu we-hydrotreating anenjinizo ngokuqondile ukuze abheke ezinhlobonhlobo zezicelo, okwenza zibaluleke kakhulu ekuhlaziyeni kwanamuhla.

KwiNaphtha, ama-catalysts ethu ahamba phambili eHydrodesulfurization (HDS) kanye nezinqubo zeHydrodenitrogenation (HDN). UNaphtha uyisihluthulelo sokuphakelayo sokukhiqizwa kukaphethiloli, futhi ukususwa kwesibabule kanye namakhompiyutha e-nitrogen kubalulekile ukukhiqiza amafutha avuthayo okuhlanza. Ama-Catalysts ethu aqinisekisa ukuthi uNaphtha uhlangabezana nokucaciswa okudingekayo, ukuhlinzeka ngokuhlaziya ngekhono lokukhiqiza uphethiloli osezingeni eliphakeme elihlangabezana namazinga alawulayo kanye nezidingo zabathengi.

Uma kukhulunywa nge-Vacuum gesi Amafutha (VGO) nodizili, ama-catalysts ethu we-hydrotreating adlala indima ebaluleke kakhulu ekuthuthukiseni ikhwalithi yalezi zinhlamvu. Izinqubo ze-HDS ne-HDN ze-VGO neDiesel zibalulekile ekukhiqizeni i-Ultra-Low Sulfur Diesel (Ulsd), ebalulekile ekunciphiseni ukuphuma kokuphuma kwezinjini zedizili. Ama-Catalysts ethu alungiselelwe ukuletha ukusebenza okuphezulu kulezi zinhlelo, eqinisekisa ukuthi ama-conferies angakhiqiza i-ulsd ehlangabezana nemithethonqubo eqinile yemvelo.

Ngaphezu kwalokho, ama-catalysts ethu e-hydrotreating nawo aphumelela ekwelapheni uphethiloli we-fluid catalytic (FCC). Izinqubo ze-HDS ne-HDN zophethiloli we-FCC zibalulekile ekususeni ukungcola okungaba nomthelela omubi ukusebenza kwenjini nokuphuma. Ngokusebenzisa ama-catalysts ethu, ama-conferies angathuthukisa ikhwalithi kaphethiloli we-FCC, enikeza abathengi ngezindlela zokuhlanza kanye nezisebenzayo zikaphethiloli.

Ukuguquguquka okuhlukahlukene kwe-serial hydrotreating catalysts yethu kungenye yezinto zabo zokusukuma. Zenzelwe ukwamukela ama-feedstocks ahlukahlukene okuphakelayo kanye nezimo zokusebenza, ezibenza zilungele izinhlobo eziningi zokucwengwa kwezicelo. Lokhu kuzivumelanisa nezimo akukwenza lula kuphela inqubo yokucwengisisa kepha futhi kuvumela ama-comfineries ukuthi asebenzise ukusebenza kwawo futhi athuthukise ukusebenza kahle kwawo.

Ekuphetheni, ukubaluleka kwama-hydrotreating carlysts embonini yokucwengisisa akunakweqiwa. Ama-catalysts ethu we-serial hydrotreating azothuthukiswa ukuze ahlangabezane nezidingo ezahlukahlukene zokuhlaziya, aqinisekise ukuthi angakwazi ukukhiqiza ama-distillates asezingeni eliphakeme ngenkathi enamathela kwimithetho yezemvelo. Noma ngabe yi-HDS ye-NAPDTA, HDS ne-HDN ye-VGO ne-Diesel, noma i-HDS ye-FCC uphethiloli, ama-carlysts ethu ahlinzeka ngokusebenza nokwethembeka okudingayo. Njengoba imboni iqhubeka nokuvela, ukutshala imali kuma-cardrotreating carlysts kuzobe kubalulekile ekufezekiseni ubuhle bokusebenza kanye nokusimama kokuhlaziywa kukaphethiloli.
