Kuyambitsa njira yopangira chomera cha TEG chosowa madzi m'thupi mu skid yochizira mpweya wachilengedwe
Njira yothira madzi ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri njira yochepetsera madzi m'thupi mu makampani opanga gasi lachilengedwe, Kusowa madzi m'thupi (TEG) (triethylene glycol dehydration) nthawi zambiri imagwiritsidwa ntchito ngati mtundu wa solvent. Imagwiritsa ntchito mfundo ya kuyamwa ndipo imagwiritsa ntchito zinthu za glycol (monga triethylene glycol) ngati zoyamwitsa kuti zigwirizane kwathunthu ndi mpweya wachilengedwe, ndikusamutsa madzi kupita ku solvent kuti athetse madzi.
Pambuyo potuluka mu nsanja, imalowa mu casing heat exchanger ndikusinthanitsa kutentha ndi hot lean glycol isanalowe mu nsanja kuti ichepetse kutentha kwa TEG. Mpweya wachilengedwe pambuyo pa kusinthana kutentha umalowa mu fyuluta yolekanitsa kuti ilekanitse glycol yonyamulidwa kenako imalowa mu pipeline yakunja. TEG yolemera yomwe yayamwa chinyezi mu mpweya wachilengedwe imatuluka kuchokera mu nsanja yoyamwa ndikulowa mu valavu yowongolera mulingo wamadzimadzi, ndipo pambuyo pochepetsa kupsinjika, imalowa mu reflux cooling coil pamwamba pa mzere wolemera wamadzimadzi ndikusinthanitsa kutentha ndi nthunzi yotentha yopangidwa mu reboiler kuti ipereke reflux pamwamba pa column. Pambuyo popereka mphamvu yozizira ya reflux pamwamba pa column, imatenthedwa mpaka pafupifupi 50 ℃, kenako imatuluka mu coil kupita ku thanki ya TEG flash. Glycol yolemera imachepetsedwa ku 0.4mpa~0.6mpa mu thanki ya flash, ndipo mpweya wa hydrocarbon ndi mpweya wina wosungunuka mu TEG umatuluka, ndipo gawo ili la mpweya limagwiritsidwa ntchito ngati mpweya wamafuta pakuyatsa reboiler.
Madzi olemera a TEG amalowa mu fyuluta yamakina kuti asefe zinyalala zamakina, kenako amalowa mu fyuluta ya kaboni yoyambitsidwa kuti apititse patsogolo zinthu za hydrocarbon zomwe zimasungunuka mu TEG ndi zinthu zowonongeka za TEG. Kenako amalowa mu chosinthira kutentha chamadzimadzi chotchedwa lean-rich liquid heat exchanger, amasinthanitsa kutentha ndi TEG yotsika kwambiri kuchokera ku thanki yosinthira kutentha yomwe ili pansi pa TEG reboiler, ndikutentha mpaka ~150 °C kuti alowe mu mzere wokonzanso madzi wolemera.
Mu TEG reboiler yomwe ili pansi pa column yokonzanso, TEG imatenthedwa kufika pa 193 ℃, ndipo madzi omwe ali mu TEG amagawidwa ndikutulutsidwa kuchokera pamwamba pa column yokonzanso kudzera mu gawo la gawo lokonzanso. Glycol yopanda mafuta yokhala ndi kuchuluka kwa pafupifupi 99% (wt) imasefukira kuchokera ku column yochotsa madzi yopanda mafuta mu reboiler kupita ku thanki yotsika ya TEG heat exchange buffer. Pansi pa mphamvu ya mpweya wouma mu column yochotsa madzi yopanda mafuta, kuchuluka kwa glycol yopanda mafuta komwe kumalowa mu thanki yosinthira kutentha kumatha kufika pa 99.5% ~ 99.8%.
Mu thanki ya glycol buffer, lean glycol yokhala ndi kutentha kwa pafupifupi 193 °C imalowa mu lean-rich glycol heat exchanger kuti isinthane kutentha ndi glycol wolemera, ndipo kutentha kumatsika kufika pafupifupi 100 °C ndikulowa mu pampu. Lean liquid TEG imapopedwa mu gas-liquid heat exchanger kunja kwa nsanja yoyamwitsa, ndipo ikazizira ndi gas heat exchanger kuchokera mu nsanja, imalowa pamwamba pa nsanja yoyamwitsa kuchokera kumtunda kwa casing kuti ikwaniritse solvent circulation.
