Chiyambi cha mayunitsi akuluakulu:
1 .1 Kupopera mpweya wa Wellhead, kuchepetsa kuthamanga kwa magazi, kuziziritsa ndi njira yolekanitsira magawo atatu
1) Kufotokozera kayendedwe ka njira
Mpweya wachilengedwe wochokera pachitsime cha gasi umapindidwa ndi kuchepetsedwa mphamvu, ndikuziziritsidwa ndi choziziritsira mpweya musanalowe mu cholekanitsa cha magawo atatu. Chifukwa cha mphamvu yokoka, chifukwa cha kusiyana kwa kuchuluka kwa mafuta ndi madzi, madzi omasuka amamira pansi pa chidebecho, ndipo mafuta amayandama pamwamba ndikukwera pamwamba pa chotchinga cha madzi a mafuta. Mbale imalowa m'chipinda cha mafuta, ndipo chowongolera madzi choyandama chimayang'anira kutulutsa mafuta osakonzedwa pogwiritsa ntchito valavu yotulutsira mafuta kuti mafuta azikhala olimba. Madzi omasuka olekanitsidwa amatuluka kudzera mu valavu yotulutsira madzi yomwe imayendetsedwa ndi chowongolera cholumikizira madzi a mafuta kuti asunge bata la mawonekedwe a mafuta ndi madzi. Mafuta olekanitsidwa amalowa mu chokhazikika kuti apitirize kulekanitsa madzi, kenako amalowa mu thanki yosungira mafuta, komwe amasonkhana mpaka kuchuluka kwina ndipo amagulitsidwa kwa ogulitsa mafuta. Chinyezi cholekanitsidwa Amalowa mu njira yotsukira zinyalala kudzera mu njira yotsekedwa yotulutsira zinyalala ndipo amatuluka akamaliza kutsukira. Mpweya wachilengedwe wolekanitsidwa umagawidwa m'magawo 6 pambuyo pokhazikitsa mphamvu, kusefa ndi kuyeza, ndipo mpweya wachilengedwe wokhala ndi liwiro la 5 MMSCMD umatumizidwa ku magawo 6 a zida zochotsera mpweya wachilengedwe motsatana. Zipangizo zazikulu zoyendetsera ntchito za gawo lililonse ndi zolekanitsa 6 za magawo atatu, zoziziritsira mpweya wachilengedwe 6, ndi zoyezera kuyenda (zogulidwa ndi mwiniwake).
2) Magawo a kapangidwe
Kuchuluka kwa mpweya wolowa mu chipangizocho: 28.3 MMSCMD
Kuthamanga kwa kulowa: 7400 psig
Kupanikizika kwa potulukira: 1218 psig
3) Mtundu wa kusintha
Kukonza katundu ndi 50% ~ 100%.
Mndandanda wa 1.2Ⅰ~ Ⅵ zipangizo zochotsera mpweya wachilengedwe
1) Kufotokozera kayendedwe ka njira
Mpweya wa Feed umalowa mu mndandanda wa I~ VI kuchotsedwa kwa mpweya wachilengedwe mayunitsi motsatana. Chigawochi chimagwiritsa ntchito yankho la MDEA kuchotsa mpweya wa acidic monga CO22 ndi H2S mu mpweya wodyetsa.
Mpweya wachilengedwe umalowa kuchokera pansi pa nsanja yoyamwitsa ndipo umadutsa mu nsanja yoyamwitsa kuchokera pansi kupita pamwamba; yankho la MDEA lokonzedwanso mokwanira (madzimadzi osalimba) limalowa kuchokera pamwamba pa nsanja yoyamwitsa ndipo limadutsa mu nsanja yoyamwitsa kuchokera pamwamba kupita pansi. Yankho la MDEA ndi mpweya wachilengedwe womwe ukuyenda mosiyana uli mu nsanja yoyamwitsa. Pambuyo pokhudzana kwathunthu, CO22 ndi H2SMu mpweya umalowa mu gawo lamadzimadzi. Zigawo zosalowa zimatengedwa kuchokera pamwamba pa nsanja yoyamwa ndikulowa mu choziziritsira mpweya chochotsa sulfurization ndi cholekanitsa. Mpweya wotuluka mu cholekanitsa mpweya chochotsa sulfurization umalowa mu chipangizo cha I~ VI series molecular sieve dehydration, ndipo condensate imapita ku flash tank.
H2Kuchuluka kwa S mu zinthu zachilengedwe zomwe zakonzedwa ndi kochepera 5 mg/Sm3.
MDEA yomwe yatenga H2S imatchedwa madzi olemera ndipo imatumizidwa ku nsanja yotulutsa mpweya. Mpweya wachilengedwe womwe umatuluka chifukwa cha kupsinjika umatumizidwa ku dongosolo la mafuta. Madzi olemera omwe amatuluka akasinthana kutentha ndi yankho (madzi ofooka) lomwe limatuluka pansi pa nsanja yobwezeretsanso, kutentha kumakwezedwa kufika ~98°C. kumtunda kwa nsanja yokonzanso, komwe kuchotsa ndi kukonzanso kumachitika mu nsanja yokonzanso mpaka mlingo wa madzi osalimba a madzi osalimba afike pa cholinga.
Madzi osalimba omwe amachokera mu nsanja yokonzanso zinthu amadutsa mu chosinthira kutentha chamadzimadzi chosalemera komanso chozizira chamadzimadzi chosalimba. Madzi osalimbawo amaziziritsidwa mpaka ~ 104°F. Pambuyo pokakamizidwa ndi pampu yamadzimadzi osalimba, amalowa kuchokera kumtunda kwa nsanja yoyamwitsa.
Mpweya womwe uli pamwamba pa nsanja yokonzanso umadutsa mu choziziritsira cha carbon dioxide ndikulowa mu cholekanitsa cha carbon dioxide. Mpweya womwe umatuluka mu cholekanitsa cha carbon dioxide umatumizidwa ku dongosolo lotulutsa carbon dioxide. Mpweya wosungunuka umakakamizidwa ndi pampu ya reflux ndikutumizidwa ku nsanja yokonzanso.
Gwero la kutentha kwa reboiler ya nsanja yokonzanso limaperekedwa ndi mafuta osamutsa kutentha kwapakati kuchokera ku makina osamutsa kutentha.
Mpweya wa asidi womwe umachotsedwa ndi makina ochotsera sulfure umatulutsidwa mwachindunji mumlengalenga. Kwenikweni palibe madzi otayira omwe amatuluka, ndipo madzi omwe amachotsedwa ndi mpweya wa asidi amatulutsidwa kudzera mu makina owonjezera ochotsera mchere; madzi omwe amachotsedwa ndi makina ochotsera madzi m'thupi amalowa mu makina ochotsera zinyalala kudzera mu makina otsekeka otulutsa madzi ndipo amatulutsidwa akadutsa mu makina ochotsera madzi.
2) Magawo a kapangidwe
Kuchuluka kwa mpweya wolowa mu nsanja yoyamwitsa ndi 5 MMSCMD pa sitima iliyonse.
Kuthamanga kwa ntchito ya nsanja yoyamwa: 1218 psig
Kutentha kwa ntchito ya nsanja yoyamwa: 104°F ~ 140°F
Kuthamanga kwa ntchito ya nsanja yokonzanso: 7.25 psig
Kutentha kwa ntchito ya nsanja yokonzanso: 203°F ~ 239°F
Gwero la kutentha kwa reboiler ya nsanja yokonzanso ndi mafuta otentha apakati (320°F).
Mpweya wa H2 S mu mpweya wochotsa sulfur ndi 5 mg/Sm3
3) Mtundu wa kusintha
Kukonza katundu ndi 50% ~ 100%.
Mndandanda wa 1.3Ⅰ~ Ⅵ zipangizo zochotsera madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe
1) Kufotokozera njira
Chipangizochi chimagwiritsa ntchito ukadaulo wothira mpweya wosinthasintha kutentha kuti chilekanitse ndi kuyeretsa mpweya. Ukadaulo wothira mpweya wosinthasintha kutentha umachokera ku kuthira mpweya wosungunuka mkati mwa mpweya (zinthu zolimba zokhala ndi porous). Mphamvu yothira mpweya wosungunuka imasintha ndi kutentha ndi kuthamanga kwa mpweya. Ngati mpweya wosungunuka umathira mpweya m'njira zosiyanasiyana, umathira mpweya wosakanikirana ndi mpweya wochepa komanso wopanikizika kwambiri, ndipo zinthu zosathira mpweya zimatuluka kudzera mu adsorber layer, ndikuthira mpweya wosungunuka ndi kutentha kwambiri komanso kotsika. Pa kuthira mpweya wocheperako komanso wopanikizika kwambiri, nsanja zingapo zothira mpweya zingagwiritsidwe ntchito kuti zikwaniritse cholinga chothira mpweya mosalekeza.
Chipangizo chowumitsira mpweya wothira mafuta chili ndi zotenthetsera zitatu zosinthira, kuphatikizapo chimodzi chothira madzi, china chothira madzi ozizira, ndi china chotenthetsera ndi kukonzanso.
Chipangizo choumitsira mpweya wothira mafuta chimagwiritsa ntchito mpweya wothira mafuta pang'ono ngati njira yozizira komanso yobwezeretsanso mpweya. Mpweya wothira mafuta ukatuluka mu nsanja yothira mafuta, umaziziritsidwa ndikulekanitsidwa kenako umakanikizidwa ndi chowonjezera mphamvu ndikutumizidwa ku nsanja yothira mafuta kuti ulowe madzi.
Mpweya wobwezeretsa mpweya umadutsa koyamba mu adsorber yozizira kuchokera pamwamba mpaka pansi. Kenako mpweya wobwezeretsa mpweya umatenthedwa kufika kutentha kwa 392 ~ 428 ° F ndi chotenthetsera chobwezeretsa mpweya, kenako umalowa kuchokera pansi pa adsorber kuti uchotse madzi omwe amatengedwa ndi adsorbent. Mpweya wobwezeretsa mpweya umatuluka pamwamba pa choumitsira mpweya, umaziziritsidwa ndi choziziritsira mpweya, kenako umalowa mu cholekanitsa mpweya wobwezeretsa mpweya. Madziwo akalekanitsidwa, amalowa mu supercharger ndipo amakanikizidwa ndikutumizidwa ku nsanja yosungira madzi kuti alowe madzi.
Madzi mu mpweya wachilengedwe wouma akadutsa mu chipangizochi, amakhala ≤ 15 ppm.
