Izici zokwakheka kweparafini eMithonjeni kawoyela kanye nezindlela zokususa iparafini

Isizathu esiyinhloko sokuthi kungani i-oil Wells wax ngesikhathi sokukhiqizwa ukuthi uwoyela ongahluziwe okhiqizwa yi-oil Wells uqukethe i-wax.

1. Izici zokwakheka kweparafini eMithonjeni kawoyela

(1) Ukwakheka kanye nokushisa kukawoyela ongahluziwe

Ngaphansi kwesimo esifanayo sokushisa, ukuncibilika kwamafutha alula ku-wax kukhulu kunokwamafutha asindayo, lapho izingxenye eziningi zokukhanya zitholakala ku-oyela ongahluziwe, kulapho izinga lokushisa le-wax lincipha khona, okungukuthi, i-wax akulula ukuyilungisa, futhi i-wax eningi yokugcina isimo sayo sincibilikile.

(2) Ingcindezi kanye negesi encibilikisiwe

Ngaphansi kwesimo sokuthi ingcindezi iphakeme kunengcindezi yokugcwala, uwoyela ongahluziwe ngeke uphume igesi lapho ingcindezi incishisiwe, futhi izinga lokushisa lokuqala lokukristala kwewaksi lizoncipha ngokuncipha kwengcindezi. Ngaphezu kwalokho, igesi encibilikisiwe nayo iyakhula futhi imunce ukushisa lapho ihlukana namafutha, okunciphisa izinga lokushisa lokugeleza kwamafutha futhi kusiza ekutholeni amakristalu ewaksi.

(3) I-Colloid kanye ne-asphaltene ku-oyili ongahluziwe

Imiphumela yokuhlolwa ikhombisa ukuthi izinga lokushisa lokwakheka kwekristalu lingancishiswa ngokwanda kokuqukethwe kwensini kuphethiloli. Kodwa-ke, lapho insini efakwe odongeni lwethubhu iqukethe insini kanye ne-asphaltene, izokwakha insini eqinile, okungelula ukuyihlanza ngokugeleza kwamafutha.

(4) Ukungcola kwemishini namanzi ku-oyili oluhlaza

Ukungcola okusemoyeni kumafutha kuzoba yingqikithi yekristalu yemvula yeparafini, okwenza amakristalu ewashi kube lula ukuwaqoqa nokuwakhulisa, futhi kusheshiswe inqubo yokuvala iwashi. Ngaphezu kwalokho, ukwakheka kwewashi kuzoba kubi kakhulu lapho okuqukethwe kwamanzi kuphansi, ngoba usawoti emanzini uyagobhoza futhi uchitheke odongeni lwepayipi, okusiza ekuqongeleleni kwamakristalu ewashi.

(5) Ijubane lokugeleza, ubulukhuni bomphezulu wepayipi

Izinga lokugeleza koketshezi emthonjeni okhiqizwayo eliphezulu, ukulahlekelwa ukushisa okuphansi, izinga lokushisa eliphezulu lokugeleza kukawoyela, i-wax akulula ukuyigwema. Ngisho noma i-wax igwema, akulula ukuyibeka odongeni lwethubhu. Uma udonga lwethubhu lukhuni, ikristalu ye-wax kulula ukunamathela kulokhu okungenhla ukuze kwakheke ukwakheka kwe-wax, kanti olunye uhlangothi akulula ukuyigwema.

2. Indlela yokususa upharafini emthonjeni wamafutha

(1) Ishidi lokuklwebha i-wax ukuze kususwe i-wax

(2) Ukuklwebha nge-wax

(3) Ukususwa kwe-parafini nge-electrothermal

(4) Ukususwa kwe-wax ye-thermochemical

(5) Ukususwa kwe-parafini yomjikelezo wamafutha ashisayo

(6) Ukususwa kwe-parafini ngomusi
