Pambuyo powala, madzi olemera a triethylene glycol amalowa mu fyuluta yamakina kuti asefe zinyalala zamakina, kenako amalowa mu fyuluta yoyatsidwa ndi kaboni kuti apititse patsogolo kuyamwa zinthu zama hydrocarbon zomwe zimasungunuka mu triethylene glycol ndi zinthu zomwe zimawonongeka za triethylene glycol. Kenako amalowa mu chosinthira kutentha chamadzimadzi cholemera komanso chopanda mphamvu cha mtundu wa mbale kuti asinthane kutentha ndi triethylene glycol yotsika kwambiri kuchokera ku thanki yotsika ya chosinthira kutentha cha triethylene glycol reboiler. Kutentha kwa kusintha kwa kutentha kumakwera kufika pa 120 ~ 130 ℃ ndikulowa mu mzere wolemera wa distillation wamadzimadzi.
Mu chotenthetsera cha triethylene glycol pansi pa chotenthetsera, triethylene glycol imatenthedwa kufika pa 193 ℃, ndipo madzi omwe ali mu triethylene glycol amagawidwa ndikutulutsidwa kuchokera pamwamba pa chotenthetsera. Kuchuluka kwa pafupifupi 99% (WT) kwa lean glycol kumasefukira mu thanki yotsika ya triethylene glycol heat exchange buffer ndi chotenthetsera cha lean liquid mu chotenthetsera. Pansi pa mphamvu ya mpweya wouma mu chotenthetsera cha lean liquid, kuchuluka kwa lean glycol kulowa mu thanki yotenthetsera kutentha kumatha kufika 99.5% ~ 99.8%.
Mu thanki ya glycol buffer, glycol yopanda mafuta yokhala ndi kutentha kwa pafupifupi 193 ℃ imalowa mu glycol heat exchanger yolemera komanso yosauka kuti isinthane kutentha ndi glycol yolemera. Kutentha kukatsika kufika pa 100 ℃, imalowa mu pampu. Triethylene glycol yamadzimadzi yopanda mafuta imapopedwa mu thermal-liquid heat exchanger yakunja ya tower of absorption ndi pampu. Pambuyo poziziritsa ndi gasi heat exchanger kuchokera mu tower, imalowa pamwamba pa tower of absorption kuchokera kumtunda kwa casing payipi kuti ikwaniritse solvent circulation.
Mpweya wouma umatuluka kuchokera ku gawo la mpweya wouma pamalo otulukira mpweya, ndipo umalowa mu chitoliro chotenthetsera mpweya wouma cha thanki yosinthira kutentha yomwe ili pansi pa chotenthetsera cha triethylene glycol. Pambuyo potenthetsera ndi triethylene glycol yopanda mafuta, umakokedwa ku 0.4MPa ndi valavu yoyendetsera kuthamanga kwa mpweya kenako umalowa mu thanki yosungira mafuta.
Zipangizo zazikulu za triethylene glycol dehydration unit (TEG dehydration unit) ndi izi:
- Seti imodzi ya separator ya fyuluta ya mpweya wodyetsa
- Seti imodzi ya nsanja yoyamwa ya triethylene glycol
- Seti imodzi ya chosinthira kutentha cha TEG chopanda mpweya
- Ma seti awiri a fyuluta yamakina yolemera ya triethylene glycol
- Seti imodzi ya fyuluta ya kaboni yolemera ya TEG
- Mapampu awiri ozungulira a TEG
- Seti imodzi ya thanki ya TEG rich liquid flash
- Seti imodzi ya thanki yosungira mafuta ya gasi
- Seti imodzi ya chosinthira kutentha cha glycol cholemera ndi chopanda madzi
- Seti imodzi ya zida zophatikizira nsanja yokonzanso ya TEG
- 1 kuchotsera pa uvuni woyaka gasi
- 1 thanki yosungiramo TEG
Kudzera mu ndondomekoyi, Kutaya madzi m'thupi pogwiritsa ntchito TEG, chiyero cha kukonzanso kwa triethylene glycol Imaposa 99%, ndipo imatha kubwezeretsedwanso mobwerezabwereza kwa miyezi 18-24, ndipo ili ndi phindu lalikulu pazachuma. Ndi yoyenera kukonzedwa kwa gasi wachilengedwe wokhala ndi kuchuluka kwakukulu komanso zosowa zochepa za mame a madzi pakusonkhanitsa ndi kutumiza.
