General
Demulsifier feem ntau tsis yog ionic surfactant, uas yog polymerized los ntawm tus neeg sawv cev pib thiab propylene oxide thiab ethylene oxide, los yog tsim los ntawm kev hloov kho lossis rov tsim cov polymer. Demulsifier yog tsuas yog siv rau lub cev qhuav dej ntawm cov roj crude los yog lub cev qhuav dej thiab desalination ntawm refinery Hoobkas.
Raws li solubility nws tuaj yeem faib ua dej -soluble thiab roj-soluble. Raws li tus neeg pib (pib tus neeg sawv cev) nws tuaj yeem muab faib ua cawv, amines, phenolic resin, phenolic aldehyde amine resin, compound initiators thiab lwm yam. demulsifier, siab flash point demulsifier, Orimulsion demulsifier thiab lwm yam.
Demulsifiers feem ntau yog siv los rhuav tshem cov emulsions ntawm cov roj crude nyob rau hauv cov roj teb thiab rau desalting thiab lub cev qhuav dej nyob rau hauv refineries. Cov neeg ua haujlwm qhuav lossis cov khoom tiav yog muaj, nrog ntau tshaj 100 tus qauv sib txawv. Cov khoom no tseem tuaj yeem txhim kho cov xwm txheej rau kev thauj mus los ntawm cov roj av thiab muaj txiaj ntsig zoo ntawm kev txo cov viscosity thiab siab.
Lub tuam txhab tsim nws tus kheej tsim cov khoom lag luam no, ua kom nrawm nrawm demulsification, tshem tawm cov dej qhuav, cov roj ntshiab - dej interface, thiab qis - kub demulsification functions. Nws tau tsom cov qauv rau ntau yam roj hnyav, roj waxy, thiab roj crude nrog cov polymers, thiab muaj cov yam ntxwv ntawm kev siv tsawg, tus nqi qis, thiab muaj zog sib xws.
Tshaj li demulsifier yog siv dav hauv cov roj av hauv zos thiab cov chaw tsim khoom, xws li Tuam Tshoj Petroleum, Sinopec, Cnooc, Sinothem, Yanchang roj av thiab xa tawm mus rau Iraq, Oman, Indonesia, Canada, Azerbaijan, Kazakhstan, Sudan thiab lwm yam lag luam thoob ntiaj teb.
Kev sib xyaw
Lub demulsifier yog lub siab -molecular compound tsim los ntawm polymerizing ntau yam pib cov neeg ua haujlwm nrog ntau pawg ua haujlwm xws li polyamines, polyols, bisepoxides, thiab ntau yam resins, nrog rau propylene oxide thiab ethylene oxide.
Dej-soluble demulsifier
Dej-soluble demulsifier yog hom tseem ceeb tshaj plaws ntawm demulsifiers hauv kev lag luam hauv tsev nrog rau tus neeg sawv cev qhuav thiab cov khoom tiav. Tus neeg sawv cev qhuav yuav tsum tau yaj hauv methanol thiab dej thaum nws siv. Cov khoom tiav tuaj yeem yaj hauv dej thiab cawv. Hom thiab kev siv nyiaj yog txiav txim siab raws li cov roj specification.

Nco tseg:Cov khoom tiav tuaj yeem siv ncaj qha, lossis siv tom qab diluted los ntawm dej.
Sib xyaw nrog roj-soluble demulsifier yog txwv tsis pub.
Roj- soluble Demulsifier
Roj-soluble demulsifier feem ntau yog siv xylene ua hnyav. Nws yog soluble hauv aromatic hydrocarbons thiab cawv thiab tsis soluble hauv dej. Lwm cov tshuaj tsw qab hydrocarbons kuj tuaj yeem siv los ua cov kuab tshuaj raws li qhov xav tau sib txawv. Hom thiab kev siv nyiaj yog txiav txim siab raws li cov roj specification.

Nco tseg:
Roj-soluble demulsifier tuaj yeem muab ntxiv rau hauv cov roj crude ncaj qha.Mixed nrog dej-soluble demulsifier yog txwv tsis pub, los yog nws yuav ntsaws lub twj tso kua mis thiab cov yeeb nkab.
Desalting demulsifier
Desalting demulsifier yog siv rau desalination thiab lub cev qhuav dej ntawm cov roj crude thiab cov roj residual los tiv thaiv catalyst lom. Cov qauv ntsuas yog raws li chloride ntsev, cov ntsiab lus ntsev tuaj yeem poob mus rau 5mNaCl / L tom qab desalination, txawm tias 3mgNaCl / L rau ntau hom roj.
