API qhov hnyav ntawm Crude
API Gravity ua haujlwm zoo li "tus neeg sawv cev txawj ntse" - los ntawm nws, peb tuaj yeem xav txog ntau yam tseem ceeb uas cuam tshuam ncaj qha rau qhov nyuaj ntawm demulsification:
1. Kev Sib Xyaws Tag Nrho ntawm Cov Roj Crude thiab Emulsion Tendency.
2. Qhov viscosity ntawm cov roj Crude thiab qhov kub ua haujlwm xav tau.
3. Hom Kev Ua Phem Rau Khoom Kho Vaj Khoom Tsev.
4. Kev Taw Qhia rau Kev Tsim Cov Tshuaj Demulsifier. -
Cov xwm txheej ua haujlwm
1. Qhov kub ntawm koj cov haujlwm roj av yog dab tsi? (Kev ua haujlwm ntawm Demulsifier yuav raug cuam tshuam los ntawm qhov kub thiab txias)2. Koj siv hom khoom siv sib cais dab tsi? (Piv txwv li, lub tank nqus dej, lub tshuab ziab dej electrostatic, thiab lwm yam, vim tias cov khoom siv sib txawv yuav xav tau cov demulsifiers sib txawv)3. Koj xav kom cov txheej txheem demulsification tshwm sim sai npaum li cas? (Kev demulsification sai yuav xav tau cov qauv tshwj xeeb) -
Cov Kev Cai Tshwj Xeeb
Koj cov kev xav tau tshwj xeeb rau kev ua haujlwm ntawm demulsification yog dab tsi? (Piv txwv li, cov dej seem hauv cov roj nyoos lossis cov roj hauv cov dej khib nyiab tom qab sib cais)Koj puas xav tau lub demulsifier los muab cov haujlwm desalting lossis cov khoom khov tshem tawm?
Dosage thiab Daim Ntawv Thov Txoj Kev?Koj puas muaj kev cia siab lossis kev txwv txog qhov ntau npaum li cas ntawm cov demulsifier? (Qhov no cuam tshuam txog cov nqi ua haujlwm thiab kev yooj yim)
Thiab thaum peb xaiv cov kuab tshuaj rau demulsifier, qhov tseem ceeb, cov khoom xyaw nquag tuaj yeem yaj tag nrho hauv cov kuab tshuaj, thiab peb yuav tsum xav txog qhov hnyav molecular, uas cuam tshuam rau qhov ceev ntawm kev sib kis hauv cov API crudes sib txawv. Yog vim li cas API thiaj li tseem ceeb.
Los ntawm kev sib txuas API Gravity nrog lwm cov ntaub ntawv tseem ceeb (BS&W, dej zoo (salinity), kub, hom khoom khov uas tsim tawm, thiab lwm yam), Peb tuaj yeem muab cov neeg siv khoom nrog kev daws teeb meem demulsification uas hloov kho tau raws li qhov xav tau, ua haujlwm tau zoo, thiab pheej yig.
Peb cov emulsion breakers tsim li cas?
Raws li qhov API gravity ntawm cov roj crude (lub teeb vs. hnyav), BS&W (qhia txog qib ntawm cov khoom khov), thiab cov xwm txheej ua haujlwm demulsification (kub, siab: kev ua haujlwm kub siab xav tau lub demulsifier thiab nws cov kuab tshuaj kom muaj kev ruaj khov thermal zoo heev), demulsifiers raug kho raws li hauv qab no:
Cov pab pawg ua haujlwm uas muaj ntau tus lej thiab qhov hnyav molecular sib txawv raug xaiv los ua cov pib. Hauv qab cov xwm txheej tshwj xeeb, cov piv sib txawv (los kho qhov HLB tus nqi ntawm demulsifier - Hydrophilic-Lipophilic Balance) thiab cov kab ke ntawm PO (lipophilic head) thiab EO (hydrophilic head) raug koom ua ke los tsim cov saw polymer ntawm ntau qhov ntev (cov saw ntev dua ua rau lub molecule lipophilicity lossis hydrophilicity zoo dua). Tom qab ntawd, cov kuab tshuaj uas muaj qhov hnyav molecular tsim nyog (muaj peev xwm yaj tag nrho cov demulsifier, qhia txog viscosity tsim nyog rau kev twj thiab txhaj tshuaj, zam kev emulsification thib ob lossis nag lossis daus, muaj cov ntsiab lus flash tsim nyog, thiab ua kom muaj kev nyab xeeb thiab kev phooj ywg ib puag ncig) raug xaiv los ua kom tiav qhov kev tsim demulsifier.

Txog Demulsifier
Nyob rau theem tom qab ntawm kev siv roj av, cov roj av emulsion feem ntau yog cov roj-hauv-dej (O/W), feem ntau nyob ua ke nrog ntau cov emulsions thiab microemulsions. Cov kua tsim tawm muaj ntau yam ntxwv nyuaj: cov dej ntau, dej dawb uas muaj roj thiab cov khoom tsis huv, ib tob tob ntawm emulsification hauv cov roj av uas muaj cov roj av, thiab muaj teeb meem loj heev rau kev qhuav dej.
Yuav kom daws tau cov teeb meem no tau zoo, yuav tsum muaj ib hom demulsifier tshiab. Lub demulsifier no yuav tsum muaj ib qho cov qauv uas yaj tau hauv dej, txuas nrog lub tswv yim ntse uas yog yooj yim rau disperse hauv cov roj crude thiab qhia tau tias zoo permeability, ua rau nws txo tau cov roj hauv cov dej khib nyiab uas tau desalted. Tshwj xeeb, cov khoom siv block copolymer demulsifiers tau hais txog rau lub hom phiaj no. Txhawm rau kom ntseeg tau tias kev ua kom lub cev qhuav sai dua thiab lub qhov cuam tshuam ntawm qhov dej qhuav siab tshaj plaws, kev tsim qauv molecular ntawm cov demulsifiers no yuav tsum suav nrog ib qho kev sib lawv liag ntawm cov thaiv thiab qhov ntev ntawm cov saw hlau.

Cov qauv demulsifier feem ntau muab cov khoom sib xyaw ua ke uas yaj tau hauv dej (xws li cov cawv rog polyoxyethylene ether, triethanolamine) thiab cov roj yaj tau hauv roj (xws li Basorol E 2032, TOMAC), thiab cov kuab tshuaj xws li cov kuab tshuaj aromatic siv los txhim kho kev yaj. Txhua yam khoom ua haujlwm los ntawm kev txhawb nqa cov dej ntws hauv daim nyias nyias, kev ua kom cov emulsion tsis ruaj khov thiab kev sib cais ntawm cov dej. Kev ua kom zoo dua ntawm cov mis yuav tsum txiav txim siab qhov kev sib xyaw ua ke zoo tshaj plaws los ntawm kev sim raws li cov xwm txheej emulsion tshwj xeeb (xws li qhov kub thiab pH).
Nws raug pom zoo kom cov neeg siv xaiv cov kev sib xyaw ua ke raws li cov yam ntxwv ntawm cov roj emulsions (xws li salinity, kub, thiab asphaltene cov ntsiab lus)
