Idizili yesulphur ephansi kakhulu (ULSD)iwuhlobo lukaphethiloli wedizili olunciphise kakhulu isibabule uma kuqhathaniswa nezibaso ezivamile zikadizili.Lolu hlobo lukaphethiloli luhlanzekile futhi lungcono endaweni ezungezile, njengoba lukhiqiza ukungcola okuncane okuyingozi uma lushisiwe.Kodwa-ke, i-ULSD inesethi yayo yezinselelo uma kukhulunywa ngokulungiswa kwemishini nokuphila isikhathi eside.

Isixazululo esisodwa salezi zinselele ukusetshenziswa kwesithasiselo sikaphethiloli sikadizili esisebenza kahle kakhulu esikwaziwa nge-HDS, noma i-hydrodesulfurization.I-HDS iyinqubo yamakhemikhali esusa isibabule nokunye ukungcola kuphethiloli kadizili, iyenze ihlanzeke futhi isebenze kahle.Kuyindlela esebenzayo yokuhlangabezana nemithetho eqinile yokukhipha umoya ngenkathi ithuthukisa nokusebenza nempilo yezinjini zikadizili.

Ukusetshenziswa kwe-HDS yeI-ULSDsekuye kwanda kakhulu eminyakeni yamuva nje, njengoba amazwe amaningi nezifunda ezamukela izindinganiso eziqinile zokukhishwa kwegesi.Eqinisweni, izinjini eziningi zikadizili nabakhiqizi bemishini batusa ukusetshenziswa kwamafutha ane-HDS ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside.

Enye yezinzuzo ezinkulu zokusebenzisa i-HDS ye-ULSD ukuthi ingasiza ekuvimbeleni ukunqwabelana kwamadiphozithi ezinjinini zikadizili.Lawa madiphozithi angabangela izinkinga eziningi, kusukela ekunciphiseni ukusebenza kahle kukaphethiloli kanye nokuphuma kwamandla kuya ekulimaleni kwenjini nokwehluleka.Izibaseli ezine-HDS nazo azijwayele ukugqwala, ezingase zikhulise isikhathi sokuphila kwezinjini nemishini kadizili.

Enye inzuzo yokusebenzisa i-HDS ye-ULSD ukuthi ingathuthukisa ukonga kukaphethiloli.Izibaseli ezishisa izikhotha ngokuvamile zikhiqiza amandla engeziwe ngeyunithi ngayinye kaphethiloli, okungase kubangele imayela elingcono legesi kanye nezindleko eziphansi zikaphethiloli.Ukwengeza, izibaseli ezine-HDS zingasiza ekunciphiseni ukuguga nokukhala kwenjini, okungase futhi kube nomthelela ekuwongeni uphethiloli kangcono ngokuhamba kwesikhathi.

Sekukonke, ukusetshenziswaI-HDS ye-ULSDkuyisinqumo esihlakaniphile sanoma ubani ofuna ukuqinisekisa ukusebenza kahle nokuphila isikhathi eside ezinjinini zabo zikadizili nemishini.Ngokususa ukungcola nokunciphisa ukungcola, i-HDS ingasiza abasebenzisi bakadizili ukuthi bahlangabezane nemithetho eqinile kuyilapho futhi yonga imali kuphethiloli nezindleko zokuwulungisa.Ngakho-ke uma ufuna ukuthola okuningi emishinini yakho kadizili, cabanga ukusebenzisa amafutha ane-HDS namuhla.

Uma kuziwa ekukhetheni umkhiqizo we-HDS, kubalulekile ukwenza ucwaningo lwakho bese ukhetha uhlobo olunegama elihle.Bheka umkhiqizo ohloliwe futhi wagunyazwa abakhiqizi benjini kadizili nemishini, futhi onomlando ofakazelwe wokuletha imiphumela.

Ngaphezu kwalokho, kubalulekile ukulandela umthamo onconywayo kanye neziyalezo zohlelo lokusebenza lapho usebenzisa i-HDS.Ukusebenzisa ngokweqile noma ukusebenzisa okungalungile empeleni kungenza umonakalo omkhulu kunokuhle, ngakho-ke kubalulekile ukulandela imihlahlandlela yomkhiqizi.

Kuyaqapheleka futhi ukuthi i-HDS ayisona isixazululo sezinhlamvu ezisiliva kuzo zonke izinkinga zenjini kadizili.Nakuba ingasiza ekuxazululeni izinkinga eziphathelene nokuqukethwe kwesibabule nokukhipha umoya, ingase ingasebenzi kahle ekubhekaneni nezinye izinhlobo zezinkinga zenjini.Njengenjwayelo, kubalulekile ukuthi unakekele futhi uhlole izinjini zakho zikadizili namathuluzi ukuze ubambe noma yiziphi izinkinga ezingase zibe khona kusenesikhathi.

Kafushane, ukusetshenziswa kwe-HDS ye-ULSD iyithuluzi elibalulekile labasebenzisi bakadizili abafuna ukuhlangabezana nezindinganiso zokukhishwa kwegesi nokuthuthukisa ukusebenza nempilo yokuphila kwezinjini zabo nezinto zokusebenza.Ngokukhetha umkhiqizo onedumela elihle nokulandela iziqondiso ezinconyiwe zohlelo lokusebenza, ungajabulela izinzuzo zezibaseli ezishisa izikhotha kanye nokonga uphethiloli okungcono.Ngakho-ke uma ubheke ukuthuthukisa imishini yakho kadizili, cabanga ngokuzama i-HDS.
