1. Zofunikira zaukadaulo

Njira ya TEG (zida zochotsera madzi m'thupi za triethylene glycol) ayenera kutsatira miyezo ndi zofunikira za dziko lonse;

Kupanikizika kwa kapangidwe ka zida: 1320 psig;

Chokwezedwa ndi skiddongosolo loyeretsa mpweyat, kayendedwe ka njira yozembera zida ndi kosalala, kapangidwe ka zida ndi koyenera, ndipo pali malo okwanira opangira ndi kukonza;

Kugwira ntchito kwa masiku 330 pachaka, ndipo zina zonse ndi kukonza;

Zipangizo za thireyi ya nsanjayo ziyenera kukhala SS 316 kapena chilichonse choyenera kutayidwa.

Mulingo wa Kapangidwe #600,

Kutentha kwa kapangidwe ka chipangizo: madigiri 200 Fahrenheit.

Taganizirani za kuchuluka kwa CO2 komwe kungachitike dzimbiri.

Zipangizo zochotsera ma amine ndi zida zina zomwe zimatha kuzizira ziyenera kupakidwa mkati.

Zipangizo zozungulira ziyenera kuchokera kwa wopanga wodalirika.

2. Kufotokozera ukadaulo wa njira

Mpweya wachilengedwe wonyowa wodzaza umadutsacholekanitsa zoseferakulekanitsa madontho a 5 μm ndi kupitirira apo, kenako kulowa mu gasi-madzimadzi olekanitsa chipangizo chochotsera madzi m'thupi kuti alekanitse madzi omasuka. Mpweya wolekanitsidwawo umalowa mu gawo loyamwa kudzera mu chitoliro chokweza mpweya cha nsanja yoyamwa. Triethylene glycol yobwezeretsedwanso imapopedwa pamwamba pa nsanja yoyamwa, ndipo imakhudzidwa kwathunthu ndi mpweya wachilengedwe kuchokera pansi kupita mmwamba pa nsanja yoyamwa kuti igwire kusamutsa ndi kusinthana kuti ichotse chinyezi. Mpweya wachilengedwe womwe chinyezi chachotsedwa umachotsedwa pa chosonkhanitsira nthunzi cha pamwamba pa nsanja kuti uchotse madontho a glycol okulirapo kuposa 5 μm kenako umatuluka mu nsanja.

Pambuyo potuluka mu nsanja, imalowa mu casing heat exchanger ndikusinthanitsa kutentha ndi hot lean glycol isanalowe mu nsanja kuti ichepetse kutentha kwa triethylene glycol. Mpweya wachilengedwe pambuyo pa kusinthana kutentha umalowa mu fyuluta yolekanitsa kuti ilekanitse glycol yonyamulidwa kenako imalowa mu pipeline yakunja. Triethylene glycol wolemera womwe watenga chinyezi mu mpweya wachilengedwe umatuluka kuchokera mu nsanja yoyamwitsa ndikulowa mu valavu yowongolera mulingo wamadzimadzi, ndipo pambuyo pochepetsa kupsinjika, umalowa 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 triethylene glycol flash tank. Glycol wolemera umachepetsedwa ku 0.4mpa~0.6mpa mu thanki ya flash, ndipo mpweya wa hydrocarbon ndi mpweya wina wosungunuka mu triethylene glycol umatuluka, ndipo gawo ili la mpweya limagwiritsidwa ntchito ngati mpweya wamafuta pakuyaka kwa reboiler.

Madzi olemera a triethylene glycol amalowa mu fyuluta yamakina kuti asefe zinyalala zamakina, kenako amalowa mu fyuluta ya kaboni yoyambitsidwa kuti apititse patsogolo kuyamwa zinthu za hydrocarbon zomwe zimasungunuka mu triethylene glycol ndi zinthu zowonongeka za triethylene glycol. Kenako amalowa mu plate-type lean-rich liquid heat exchanger, amasinthanitsa kutentha ndi lean-temperature triethylene glycol yochokera mu thanki yosinthira kutentha yomwe ili pansi pa triethylene glycol reboiler, ndipo amatentha mpaka ~150 °C kuti alowe mu column yokonzanso madzi yolemera.

Mu triethylene glycol reboiler yomwe ili pansi pa column yokonzanso, triethylene glycol imatenthedwa kufika pa 193 ℃, ndipo madzi omwe ali mu triethylene glycol amagawidwa ndikutulutsidwa kuchokera pamwamba pa column yokonzanso kudzera mu gawo la gawo lokonzanso. Lean glycol yokhala ndi kuchuluka kwa pafupifupi 99% (wt) imasefukira kuchokera ku column yochotsa madzi mu reboiler kupita ku thanki yotsika ya triethylene glycol heat exchange buffer. Pansi pa mphamvu ya mpweya wouma mu column yochotsa madzi, kuchuluka kwa lean glycol komwe kumalowa mu thanki yosinthira kutentha kumatha kufika 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 triethylene glycol 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.

Mpweya wouma wochokera ku gawo la chitoliro cha mpweya wouma pamalo otulukira nsanja yoyamwitsa ndi mpweya wochotsa mpweya wa mzati wokonzanso.
