HLN-127 Tshuaj Tiv Thaiv Kev Xeb Tsis Zoo Rau Cov Chav Distillation Hauv Huab Cua Thiab Hauv Lub Tshuab Nqus Tsev
Cov yam ntxwv ntawm cov khoom
- Kev Tswj pH: Tswj cov pH ntawm cov dej condensed kom nyob rau hauv 5.5 txog 6.0, sib npaug ntawm cov kua qaub corrosion thiab under-scale corrosion los ntawm NH4Cl thiab FeS.
- Kev Ua Haujlwm Zoo: Txo kev siv tus neeg sawv cev ntau dua 20% piv rau cov khoom zoo sib xws, ua tiav qhov kev tiv thaiv xeb ntawm ≥90%.
- Kev Tiv Thaiv Emulsification: Txo qhov kev nyiam ntawm cov dej condensed los tsim cov emulsions, txo cov roj thiab COD hauv cov dej theem.
- Kev Nyab Xeeb Ib Puag Ncig: Tsis muaj hlau thiab cov khoom phom sij, ua kom tsis muaj kev cuam tshuam tsis zoo rau cov chaw ua haujlwm hauv qab lossis cov tshuab kho dej khib nyiab.

Cov ntawv thov
- Kev Tswj Xyuas Kev Xeb: Tiv thaiv kev xeb HCl-H2S-H2O hauv cov tshuab cua txias saum toj ntawm cov chaw lim dej hauv huab cua thiab cov chaw lim dej.
- Kev Txo Qhov Loj: Tiv thaiv ammonium chloride (NH4Cl) thiab hlau sulfide (FeS) kom loj, zam kev xeb thib ob thiab ua kom cov khoom siv siv tau ntev.
Cov Lus Qhia Siv
1. **Kev Npaj:** Muab cov khoom no tso rau hauv lub tank uas tiv thaiv xeb thiab muab nws sib tov nrog dej uas tsis muaj mineralized lossis dej uas tsis muaj oxygen kom txog thaum nws muaj concentration raws li qhov xav tau.
2. **Cov Chaw Txhaj Tshuaj:** Siv lub twj ntsuas los txhaj cov tshuaj inhibitor ua ntej qhov chaw txhaj tshuaj dej ntawm txoj kab evaporation nyob rau sab saum toj ntawm lub thawv distillation, zoo tshaj plaws yog ze rau qhov chaw dew point.
3. **Dosage:** Kho qhov nrawm ntawm kev txhaj tshuaj kom tswj tau pH ntawm cov dej noo ntawm 5.5 thiab 8.0. Cov koob tshuaj ib txwm muaj: 10-40ppm (piv rau cov roj nyoos). Cov koob tshuaj pib yuav raug nce ntxiv kom tsim kom muaj qhov sib npaug ntawm kev nqus.
4. **Kev Kho Kom Haum:** Hloov kho qhov nrawm ntawm kev txhaj tshuaj raws li cov yam ntxwv ntawm cov roj nyoos (cov organic chlorine thiab sulfur), cov theem ntawm cov condensate chloride ion, thiab cov ntaub ntawv saib xyuas xeb.
Kev Pov Thawj Ua Tau Zoo
- Tswj cov hlau ion concentration hauv cov dej condensed ntawm cov ntsiab lus tseem ceeb (piv txwv li, lub pej thuam distillation thawj zaug, lub pej thuam atmospheric, thiab lub pej thuam vacuum) yog ≤3mg / L.
- Tsis ua rau emulsification lossis cuam tshuam rau kev sib cais roj-dej, kev ruaj khov ntawm lub cuab yeej, lossis qhov zoo ntawm cov khoom.
- Tsis muaj teeb meem tsis zoo rau cov chaw ua haujlwm hauv qab lossis cov tshuab kho dej khib nyiab.
- Cov Tshuaj Pom Zoo: Raws li cov yam ntxwv ntawm cov roj nyoos, cov lus hauv qab no muab cov lus qhia txog kev txhaj tshuaj neutralizer.
