Mpweya wachilengedwe womwe umangotuluka m'chitsime nthawi zambiri umadzazidwa ndi nthunzi yamadzi yokhuta, yomwe ingayambitse mavuto aakulu. Mpweya wachilengedwe wokhala ndi zinthu zokhala ndi asidi umatha kuwononga mapaipi ndi zida zake ngati pali madzi; Chinyezi chingachepetse mphamvu yonyamulira mapaipi achilengedwe ndikuyambitsa kugwiritsa ntchito mphamvu zosafunikira. Chifukwa chake, kusowa madzi m'thupi chifukwa cha mpweya wachilengedwe ndikofunikira kwambiri.
Kutaya madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe ndi njira yomwe imagwiritsa ntchito njira zina zochotsera nthunzi yamadzi yokhuta kuchokera ku mpweya wachilengedwe. Njira zodziwika bwino zimaphatikizapo kuziziritsa madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe, kusowa madzi m'thupi chifukwa cha zosungunulira, kusowa madzi okwanira m'thupi, kusowa madzi m'thupi kudzera mu nembanemba, ndi zina zotero. Njira zosiyanasiyana zochotsera madzi m'thupi zimakhala ndi makhalidwe awoawo ndipo ndizoyenera malo osiyanasiyana.
Njira yayikulu yogwiritsira ntchito triethylene glycol ndi iyi:
Mpweya wachilengedwe wonyowa mu mkhalidwe wokhuta umalekanitsidwa ndi cholekanitsa cha fyuluta kuti chilekanitse madontho amadzimadzi a 5 μ m ndi kupitirira apo, kenako chimalowa mchipinda cholekanitsa gasi ndi madzi chomwe chili pansi pa nsanja yoyamwa ya triethylene glycol ya unit yochotsera madzi kuti chilekanitse madzi omasuka omwe angabweretsedwe mu nsanja yoyamwa pamene cholekanitsa cha fyuluta chili mu mkhalidwe wa ngozi. Lowani mu gawo loyamwa kudzera mu riser ya nsanja yoyamwa. Triethylene glycol yobwezeretsedwanso imapopedwa pamwamba pa nsanja yoyamwa kuti igwirizane kwathunthu ndi mpweya wachilengedwe kuchokera pansi kupita mmwamba pa nsanja yoyamwa kuti isamutse misa ndikuchotsa chinyezi. Mpweya wachilengedwe wouma umatulutsidwa mu nsanjayo mutachotsa madontho a glycol opitilira 5 μ m kudzera mu chogwirira nthunzi cha tower top.
Pambuyo potuluka mu nsanja, kutentha kumasinthidwa ndi glycol yotentha yopanda mafuta asanalowe mu nsanja kudzera mu chosinthira kutentha cha tubular kuti achepetse kutentha kwa triethylene glycol yomwe imalowa mu nsanja. Pambuyo posintha kutentha, mpweya wachilengedwe umalowa mu cholekanitsa fyuluta kuti ulekanitse glycol yonyamula kenako umalowa muipi yotumizira kunja. Triethylene glycol yolemera (TEG), yomwe imatenga chinyezi mu mpweya wachilengedwe, imatuluka mu nsanja yoyamwa ndikulowa mu valavu yowongolera mulingo wamadzimadzi. Pambuyo pochepetsa kupsinjika, imalowa mu mbale yoziziritsira ya reflux pamwamba pa mzere wolemera wamadzimadzi kuti isinthane kutentha ndi nthunzi yotentha yopangidwa mu reboiler. Pambuyo popereka mphamvu yozizira ya reflux pamwamba pa mzere, triethylene glycol yolemera imatenthedwa mpaka pafupifupi 50 ℃. Chubu chotulutsira chimalowa mu thanki ya TEG flash. Glycol yolemera imachepetsedwa ku 0.4MPa ~ 0.6MPa mu thanki ya flash. Mpweya wa hydrocarbon ndi mpweya wina wosungunuka mu TEG umatenthedwa, ndipo mpweya uwu umagwiritsidwa ntchito ngati mpweya wamafuta pakuyatsa reboiler.
