Demulsifier
| Vim tias qee cov khib nyiab hauv dej, thaum ib lossis ntau dua ntawm cov khib nyiab no muaj nyob hauv cov pa roj aqueous nyob rau hauv ib lub aqu aquា stateeous Oxis, lawv tuaj yeem muaj zog nyob rau hauv ib lub hwj chim hauv qab hydraulic lossis sab nraud zog, ua ib qho kev emulsion. Theoretically lub system no tsis ruaj khov, tab sis yog tias muaj qee qhov surfactants loj, txawm tias ob ntu yog cov khoom siv roj ntau dua yog cov dej sib tov Nyob rau hauv cov roj-dej sib cais thiab cov dej-roj sib xyaw hauv cov qauv dej pheebsium lossis dej-hauv-roj-roj, tus qauv txheej txheem hluav taws xob ". Hauv qhov no, qee tus neeg sawv cev tau muab tso rau hauv kev cuam tshuam nrog lub zog hluav taws xob bilayer zoo li mus ua tiav lub zog emulsification kom ua tiav txoj kev sib cais ntawm ob ntu. Cov tshuaj tiv thaiv no tau siv los ua tiav qhov cuam tshuam ntawm emulsification yog hu ua emulsion tej fais fab. |
Cov ntawv thov MAIN
| Demulsifier yog ib qho khoom siv surfactant, uas tuaj yeem ua rau cov qauv ua kom zoo, txhawm rau ua tiav lub hom phiaj ntawm emulsion hauv ntau ntu theem. Cov roj roj Roj deemulate yog hais txog kev siv cov tshuaj lom neeg uas emulsion remulation kom ua tiav cov txheej txheem ntawm cov roj hmab roj tawg, kom ntseeg tau tias cov qauv ntawm cov txheej txheem roj av rau sab nraud kev sib kis. Kev sib cais ua tau zoo ntawm cov organic thiab aqueous theem, ib qho ntawm cov txheej txheem yooj yim thiab cov txiaj ntsig zoo tshaj plaws los ua lub zog emulsified kom ua tiav qhov kev sib cais kom ua tiav txoj kev sib cais ntawm ob theem. Txawm li cas los xij, sib txawv defulsif nyias muaj qhov sib txawv emulsion lov rau cov organic theem, thiab kev ua tau zoo ntawm nws cuam tshuam rau ob-theem sib cais ua haujlwm. Nyob rau hauv cov txheej txheem ntawm kev siv penicillin, ib tus txheej txheem tseem ceeb yog los rho cov kab mob los ntawm penicillin fermentation broth nrog cov kuab tshuaj organic (xws li Butyl acetate). Txij li thaum fermentation broth muaj cov nyom ntawm cov protein, cov piam thaj, mycelification yog ib qho kev siv, uas muaj kev cuam tshuam zoo rau cov khoom tiav ntawm cov khoom tiav. |
Cov demulsifier ntau yam - hauv qab no yog lub ntsiab tsis-ionic demulsifier ib txwm siv nyob rau hauv lub oilfield.
Sp-hom demulsifier
| Lub ntsiab tivthaiv ntawm SP-hom breaker yog polyoxyylropene polyoxyprropylene podula yog R (PO) Z (PO) Zh, qhov twg: eo-polyoxyethylene; Po-PolyoxyPropene; R-Aliphatic Cawv; x, y, z-polymerization degree.Sp-hom demulsifier muaj cov tsos ntawm lub teeb daj muab tshuaj txhuam, tus nqi HLB ntawm 10 ~ 12, soluble hauv dej. SP-hom cov tsis-ionic demulsifier tau zoo dua cuam tshuam rau cov roj paraffin raws li cov roj paraffin. Nws cov tshuaj hydrophobic muaj cov pa roj carbon 12 ~ 18 Hydrophilic los ntawm kev txiav txim ntawm hydroxyl (-o-) pawg nyob rau hauv molecule thiab dej los ua hydrogen bonds. Txij li cov pab pawg hydroxyl thiab ether zog tsis muaj zog hydrophilic, tsuas yog ib lossis ob pawg hydrophibic tsis tuaj yeem rub tau ntau dua ib lub hom phiaj ntawm cov dej solubility. Qhov loj dua cov molecular qhov hnyav ntawm cov tsis-ionic demulsifier, qhov ntev dua cov molecular, qhov ntau dua nws cov kev tshem tawm muaj peev xwm uas muaj zog roj tawg. Lwm qhov laj thawj yog vim li cas spemulsifier yog qhov haum rau cov roj uas muaj cov roj ntsha tsis muaj lossis cov roj ntsha tsis muaj txiaj ntsig, tsawg dua lipophilic surfactant cov tshuaj thiab tsawg tus txheeb ze. Rau cov roj nyoos nrog cov pos hniav ntawm cov pos hniav thiab dej ntau dua 20%), qhov teeb meem tsis muaj zog ntawm cov qauv molulsifer thiab tsis muaj cov ceg qauv thiab cov qauv sib dhos. |
AP-YAM DEMULLEMIF
| Ap-hom demulshlene polyoxyprropeny polyether nrog polyethylene polyamine raws li cov qauv molecular, oo) zh, qhov twg: eo - polyoxyethylene; PO - polyoxyprropene; R - dej cawv; D - Polyethylene amine: x, y, z - degree ntawm polymerization. AP-hom qauv demulsifier rau paraffin raws li cov txiaj ntsig roj av ntau dua 20% yog qhov tsim nyog dua rau cov roj av remulsifiing, thiab tuaj yeem ua tiav cov txiaj ntsig nrawm nrawm hauv qhov kub tsawg tej yam kev mob. Yog hais tias tus sp-hom demulsifier sundles thiab demulsify lub emulsion nyob rau hauv 55, tus apulsify lub emulsion nyob rau hauv 45 ~ 50 ℃ thiab 1.5H. Qhov no yog vim yog cov qauv kev coj ua ntawm AP-YAM DISFULSIFER MOLECLE. Tus thawj pib txiav txim siab cov qauv txheej txheem ntawm cov qauv ntawm cov qauv: cov molrophilic muaj peev xwm ntev dua li ntawm sp-hom demulsifier nrog ib qauv molecular. Cov yam ntxwv ntawm ntau-ceg saw txiav txim siab ap-hom demulslity muaj cov khoom sib xyaw rau cov roj av, dua li cov qauv roj demulsifier molecules ntawm qhov ntsug Ib qho molecule zaj duab xis npaj hauj lwm muaj ntau thaj chaw thaj tsam ntau thaj chaw, yog li tsawg dua, emulsion rhuav cov nyhuv yog pom tseeb. Ntawm tam sim no, hom kev demulsifier yog qhov zoo dua tsis-ionic demulsifier siv nyob rau hauv daqing oilfield. |
AE-hom demulsifier
| AE-hom demulshlenier yog polyoxyylropene polyethetly polyether nrog polyethylene polyamine raws li pib hom ntawm kev tsis muaj keeb kwm ntawm kev tsis muaj kev paub. Piv nrog ap-hom demulsifier, qhov sib txawv yog tias AE-hom demulsifier yog ob-theem polymer nrog cov saw me me thiab luv luv saw. Molecular qauv qauv yog: D (PO) X (EO) YH, qhov twg: PO - PolyoxyPropene: D - Polyethylene Polyamine; x, y - degree ntawm polymerization. Txawm hais tias cov theem molecular ntawm AE-hom demulsifier muaj ntau yam, tab sis cov molulsitionifier muaj tib yam, tsuas yog nyob rau hauv monomer ntau npaum li cas thiab kev txiav txim siab polymerization sib txawv. (1) Ob qho tsis yog-ionic demulsifier hauv cov qauv ntawm synthesis, lub taub hau thiab tus tw ntawm cov nyiaj siv sib txawv, ua rau muaj kev sib txawv ntawm polymerization kuj txawv. (2) AP-hom demulsifier molecule yog bipartylene polyamine raws li tus pib, thiab polyoxyylore, thiab polyoxyylore, thiab polyoxyylore, polyoxyprropeny polymerization polymerization rau daim ntawv Ob tug copolymers, yog li ntawd, tus tsim ntawm ap hom demulsifier molecule yuav tsum ntev dua li ae-hom demulsifier lwg me me. AE-hom yog ob-theem qauv teeb tsa txiv neej muaj ntau cov roj roj demulsfuls, uas tseem yoog raws li cov phev roj uas tawg paj tawg. Qhov ntau cov ntsiab lus ntawm lipophilic surfactant hauv bituminous rabe roj, qhov me dua qhov sib txawv ntawm cov roj thiab dej ntom, tsis yooj yim rau kev cuam tshuam lub emulsion. AE-hom demulsifier yog siv los rhuav tshem emulsion nrawm, thiab tib lub sijhawm, AE-hom demulsifier yog qhov zoo dua los tiv thaiv tus roj liab. Vim nws cov qauv ntau-ceg ntawm cov lwg me me, yog li ntawd cov roj av uas tau txav mus rau hauv cov khoom siv ua pa tsw qab ntawm ib leeg lwm yam, kev sib sau cov qauv khoom ntawm paraffin, txo lub viscosity thiab tiv thaiv kev sib sau ua ke ntawm wax muaju, yog li ua tiav lub hom phiaj ntawm anti-ciab. |
Ar-hom demulsifier
| AR-hom demulsifier yog ua los ntawm alkyl phenholog resin (Ar resin) thiab polyoxypropene, polyic tus nqi ntawm li 4 ~ 8, qis demulationing kub ntawm 35 ~ 45 ℃. Cov qauv molecular qauv yog: ar (po) x (eo) yh, qhov twg: eo-polyoxyethylene; Po-PolyoxyPropene; Ar-cob; x, y, z-degree ntawm polymerization.Nyob rau hauv cov txheej txheem ntawm synulsizing demulsifier, arsin ua raws li ob qho pib thiab nkag mus rau hauv molulsifier los ua lipothilic pab pawg. Cov yam ntxwv ntawm Ar-hom demulsifier yog: lub molecule tsis loj, diffusion, kev nkag mus rau cov dej ntws tawm, sai sai emulsified dej flocculation, agglomeration. Nws tuaj yeem tshem tawm ntau dua 80% ntawm cov dej los ntawm cov roj nyoos nrog cov roj hmab dej ntawm 50% ntawm cov dej hauv qab no nrog rau cov roj av nrog cov dej hauv 50% txog 70%, uas yog incomparable rau sp-hom thiab ap hom demulsifier. |
