I-HEC Yezinga Likaphethiloli: Ukukhulisa Ukukhishwa Kukawoyela Negesi Okusebenzayo

I-hydroxyethyl cellulose ye-Petroleum-grade (HEC), njengesithako esibalulekile se-polymer esincibilika emanzini, isilungisi se-rheology, kanye nesiqinisi, siye saba yigugu kakhulu emkhakheni wokukhipha uwoyela negesi eminyakeni yamuva nje. Ngokukhula okuqhubekayo kwemithombo ejulile, imithombo ejulile kakhulu, kanye nokuhlolwa okungajwayelekile kukawoyela negesi, izidingo eziphakeme zibekwa ekusebenzeni koketshezi lokubhoboza, uketshezi lokuqhekeka, kanye noketshezi lokuqedwa. I-HEC, ngokuncibilika kwayo okuhle kakhulu, ukuzinza kwamakhemikhali, kanye nekhono lokujiya, isibe yisithako esibalulekile sokuthuthukisa ukusebenza kahle kokukhipha uwoyela negesi.

I-HEC esezingeni likaphethiloli ikhombisa ukuncibilika kwamanzi okuhle kakhulu kanye nezakhiwo zokujiya, yakha ngokushesha uhlelo olufanayo lapho kulungiswa uketshezi lokubhoboza, yandisa ukujiya koketshezi, ngaleyo ndlela ithuthukise umthamo wokuthwala ukusika. Ngesikhathi sokubhoboza, ukusika okungaphansi komthombo kudinga ukususwa ngempumelelo ngaphansi kwezimo zokushisa okuphezulu, umfutho ophezulu, kanye nokujikeleza okusheshayo. Uketshezi lokubhoboza olujiyile lwe-HEC luthuthukisa amakhono okumiswa nokuthutha, luthwala ukusika ngokushesha luye ekhanda lomthombo futhi lugweme ingozi yokunamathela kwepayipi lokubhoboza okubangelwa ukuqongelela ukusika phansi komthombo. Ngaphezu kwalokho, i-HEC ihambisana kahle namanzi acwebile namanzi olwandle, igcina ukusebenza okuqinile kokujiya ngisho nasezindaweni ezinosawoti omningi, okwenza ifaneleke kakhulu kumapulatifomu asogwini kanye nemisebenzi yokwakheka eyinkimbinkimbi.

I-HEC idlala indima ebalulekile ekuqedeni nasekuqiniseni izinhlelo zoketshezi. Ithuthukisa ukuziphatha kwe-rheological koketshezi, igcina ukulahleka koketshezi okuphansi futhi ithuthukise ikhwalithi yekhekhe lokuhlunga. Ikhekhe lokuhlunga elisezingeni eliphezulu, elincane, neliqinile lihlukanisa ngempumelelo uketshezi lokwakheka, linciphise umonakalo echibini futhi liqinisekise ukuzinza komkhiqizo olandelayo. Ngaphezu kwalokho, i-HEC ithuthukisa kakhulu uketshezi oluhambisanayo kanye namandla okumiswa kwe-propant loketshezi lokuqeda, ikhuthaza ukusebenza okubushelelezi nokuphephile.

Kubuchwepheshe bokuqhekeka, i-HEC yezinga likaphethiloli iyisici esibalulekile soketshezi lokuqhekeka olusebenza kahle kakhulu. Amandla ayo okujiya avumela uketshezi lokuqhekeka ukuthi luthwale inani elikhulu le-propant liye ekuqhekekeni okujulile, kufezwe ukuguqulwa okusebenzayo kwedamu. Ngesikhathi sokuqhekeka, amazinga okushisa namandla okucheba aphezulu kakhulu, kodwa i-HEC igcina izakhiwo ezinhle ze-viscoelastic, inciphisa ukuqina kwesihlabathi futhi ithuthukise ukwesekwa kokuqhekeka. Ngakolunye uhlangothi, i-HEC inezici zokuwohloka ezingalawuleki; ngemuva kokwakhiwa, ingawohloka ngaphansi kwezimo ezifanele, ikhulule ekuqhekekeni, inciphise ukumelana nokugeleza emuva, iqinisekise ukugeleza kukawoyela negesi okubushelelezi, ngaleyo ndlela ikhulise ukukhiqizwa. Ngokuphathelene nokuvikelwa kwemvelo nokuphepha, i-HEC ayinaboli, iyabola, futhi ayicasuli, okwenza ibe yisithasiselo samakhemikhali esiluhlaza nesinobungani nemvelo. Ngokuphambene nokugcizelelwa komhlaba wonke kwamandla aluhlaza kanye nentuthuko esimeme, i-HEC ayihlangabezani nje kuphela nezidingo zamanje zemvelo zamakhemikhali asezindaweni zikawoyela kodwa futhi isiza izinkampani ukuthuthukisa amazinga azo okuphathwa kwemvelo. Uma kuqhathaniswa nama-polymers endabuko okwenziwa, i-HEC inobungani bemvelo obungcono kanye nokuphepha kokugcina kanye nokuthutha, okuvumela uhlelo lokumiswa kwamakhemikhali oluphansi kanye noluphephile ekuthuthukisweni kukawoyela negesi.

Ukusetshenziswa kwe-petroleum-gradeI-HECikwandise futhi yaya emikhakheni eminingi, okuhlanganisa ukuvuselelwa kwamafutha okuthuthukisiwe, ukuvikelwa kwedamu, kanye nokwenza ngcono ukusebenza kwesistimu yoketshezi lokubhoboza. Ukuhambisana kwayo ezinhlelweni ezahlukene zoketshezi kuyivumela ukuthi isebenze ngokubambisana nama-surfactants ahlukahlukene, usawoti, kanye nama-agent okuxhumanisa ukuze kwakheke izinhlelo zamakhemikhali zensimu kawoyela ezisebenza ngezindlela eziningi. Isibonelo, ekukhishweni kwamafutha amaningi, i-HEC ingathuthukisa i-rheology yesistimu yokufakwa futhi yandise ukusebenza kahle kokufakwa; ekusebenzeni kwemithombo yegesi, uhlelo lokuqina lwe-HEC lungathwala futhi lukhiphe uketshezi ngempumelelo, luthuthukise ukukhiqiza kwemithombo yegesi.

Ngenxa yokuqina kwayo okuhle kakhulu, ukumiswa, izakhiwo zokulungisa imithambo yegazi, kanye nezici ezinhle zemvelo, i-HEC yezinga likaphethiloli isibe yinto ebalulekile ekukhishweni kukawoyela negesi okusebenzayo kwesimanje. Kungakhathaliseki ukuthi kusekubholeni, ekusimeni, ekuqhekekeni, noma ekusebenzeni kokuqedwa, i-HEC ingathuthukisa kakhulu ukusebenza kahle kwenqubo kanye nokuphepha kokusebenza, okunegalelo ekuthuthukisweni okusebenzayo kanye nokusetshenziswa okusimeme kwezinsiza zikawoyela negesi.
