Kev Pabcuam Roj Refining
HLN-127-4 Tshuaj Tiv Thaiv Dej Thiab Kev Xeb (Plaub Zaug Cov Tshuaj Uas Muaj Concentrated)
Cov yam ntxwv ntawm cov khoom
- Kev Ua Haujlwm Zoo Tshaj Plaws ntawm Kev Tiv Thaiv Kev Xeb: Tiv thaiv tau zoo tiv thaiv kev xeb txawm tias nyob hauv cov sulfides thiab chlorides ntau. Cov tshuaj tiv thaiv kev tsis sib haum xeeb tuaj yeem npaj tau tom qab 4-5 zaug dilution.
- Kev Sib Koom Tes Yooj Yim Nrog Neutralizers: Sib xws nrog ethylenediamine, monoethanolamine, thiab lwm yam organic amine neutralizers rau kev siv ncaj qha.
- Kev Nyab Xeeb Ib Puag Ncig: Tsis muaj Cl, P, thiab cov hlau ions. Cov khoom seem yog yaj hauv dej, kom ntseeg tau tias tsis muaj kev cuam tshuam tsis zoo rau kev ua haujlwm tom qab.
- Kev Ua Haujlwm Tiv Thaiv Kev Ua Kom Tsis Muaj Dej: Txo qhov kev nyiam ua kom tsis muaj dej sib xyaw, xyuas kom ua raws li ammonia nitrogen, COD, thiab cov qauv tswj cov roj.
- Tus nqi tsim nyog: Tsuas yog xav tau ntxiv cov organic amines, ua rau tus nqi tag nrho qis dua.
- Kev Siv Dav Dav: Tau ua pov thawj tias muaj txiaj ntsig zoo rau ntau yam khoom siv hauv tsev, ua rau nws haum rau cov chaw lim dej hauv huab cua thiab lub tshuab nqus tsev uas muaj ntau yam khoom thiab kev ua haujlwm sib txawv.

Cov ntawv thov
- Chav Refinery: Kev tiv thaiv xeb rau cov ntu txias uas kub tsawg hauv atmospheric distillation, vacuum distillation, catalytic cracking, thiab hydrogenation units.
Cov Lus Qhia Siv
1. **Kev Sib Xyaws:** Muab cov khoom sib xyaws 4–5 zaug nrog dej thiab sib tov nrog cov tshuaj uas ua rau cov tshuaj tsis muaj zog.
2. **Kev Npaj Neutralizer:** Rau cov khoom siv distillation hauv huab cua thiab hauv lub tshuab nqus tsev, ntxiv 10–20% ethylenediamine lossis 15–30% monoethanolamine rau ib tuj ntawm cov khoom tiav.
Kev Ntim Khoom, Kev Khaws Cia, thiab Kev Nyab Xeeb
- Cov Kev Xaiv Ntim Khoom: Muaj nyob rau hauv 25L yas nruas, 200L hlau lossis yas nruas, lossis IBC tuj thoob.
- Cov Lus Qhia Txog Kev Khaws Cia: Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau rau hauv chav tsev uas kub thiab txias. Xyuas kom lub thawv kaw ruaj. Lub sijhawm khaws cia yog 2 xyoos.
- Kev Ceev Faj Txog Kev Nyab Xeeb: Khaws cia kom deb ntawm cov chaw uas muaj hluav taws. Saib Daim Ntawv Qhia Txog Kev Nyab Xeeb Khoom Siv (MSDS) kom paub cov ntaub ntawv qhia txog kev nyab xeeb.
