Igesi yendalo emanzi xa igcwele yahlulwe sisihluzo sokwahlulahlula amathontsi olwelo angama-5 μ m nangaphezulu, ize ingene kwigumbi lokwahlulahlula igesi nolwelo elisezantsi. Inqaba yokufunxa i-TEG (i-Triethylene gly) ye iyunithi yokuphelisa amanzi emzimbeni ukwahlula ulwelo olukhululekileyo olunokungeniswa kwinqaba yokufunxa xa isahluli sesihluzo sikwimeko yengozi. Ngena kwicandelo lokufunxa nge-riser yenqaba yokufunxa. I-TEG ehlaziyiweyo ipompelwa phezulu kwinqaba yokufunxa ukuze iqhagamshelane ngokupheleleyo negesi yendalo ukusuka ezantsi ukuya phezulu kwinqaba yokufunxa ukuze kudluliswe ubunzima kunye nokususwa komswakama. Igesi yendalo eyomileyo ikhutshwa kwinqaba emva kokususa amaconsi e-glycol angaphezu kwe-5 μ m nge-tower top mist catcher.
Emva kokuphuma kwinqaba, ubushushu butshintshiselwana ne-hot lean glycol ngaphambi kokuba ingene kwinqaba nge-tubular heat exchanger ukunciphisa ubushushu be-TEG engena kwinqaba. Emva kokutshintshwa kobushushu, igesi yendalo ingena kwi-filter separator ukuze yahlule i-carrier glycol ize ingene kwi-export pipeline. I-TEG etyebileyo, efunxa umswakama kwigesi yendalo, iphuma kwi-absorption tower ize ingene kwi-liquid level control valve. Emva koxinzelelo, ingena kwi-reflux cooling plate ephezu kwe-rich liquid distillation column ukuze itshintshiselane nobushushu ngomphunga oshushu owenziwe kwi-reboiler. Emva kokubonelela ngomthamo wokupholisa we-reflux we-column top, i-TEG etyebileyo ifudunyezwa ukuya kuthi ga kwi-50 ℃. Ityhubhu yokuphuma ingena kwi-TEG flash tank. I-rich glycol ixinyelelwe ukuya kuthi ga kwi-0.4MPa ~ 0.6MPa kwi-flash tank. Igesi ye-hydrocarbon kunye nezinye iigesi ezinyibilikisiweyo kwi-TEG ziyacinywa, kwaye ezi gesi zisetyenziswa njengegesi yamafutha ekutshisweni kwe-reboiler.
Emva kokukhazimla, i-TEG etyebileyo yolwelo ingena kwi-mechanical filter ukuze ihluze ukungcola koomatshini, ize ingene kwi-activated carbon filter ukuze ifunxe ngakumbi izinto ze-hydrocarbon ezinyibilikiswe kwi-TEG kunye nezinto eziwohlokayo ze-TEG. Emva koko ingena kwi-plate sheet rich and minor heat exchanger ukuze itshintshise ubushushu nge-TEG ethambileyo yobushushu obuphezulu evela kwi-heat exchange buffer esezantsi ye-TEG reboiler. Ubushushu botshintshiselwano lobushushu bunyuka bufike kwi-120 ~ 130 ℃ kwaye bungene kwikholamu ye-liquid distillation etyebileyo.
Kwi-TEG reboiler ezantsi kwikholamu ye-distillation, i-TEG ifudunyezwa ukuya kwi-193 ℃, kwaye amanzi kwi-TEG ayahlulwahlulwa aze akhutshwe phezulu kwikholamu ye-distillation. Uxinzelelo olumalunga ne-99% (WT) ye-lean glycol lugcwala kwi-TANK ye-TEG heat exchange buffer esezantsi yi-lean liquid stripping column kwi-reboiler. Phantsi kwesenzo segesi eyomileyo kwikholamu ye-lean liquid stripping, uxinzelelo lwe-lean glycol engena kwi-tank ye-heat exchange buffer lunokufikelela kwi-99.5% ~ 99.8%.
Kwitanki ye-glycol buffer, i-glycol engenamandla enobushushu obumalunga ne-193 ℃ ingena kwi-glycol heat exchanger etyebileyo nembi ukuze itshintshise ubushushu ne-glycol etyebileyo. Xa ubushushu buhla bufikelela kwi-100 ℃, ingena kwimpompo. I-TEG engenamandla iphonswa kwi-external gas-liquid heat exchanger ye-absorption tower ngepompo. Emva kokuba ipholile nge-gas heat exchanger iphuma kwi-tower, ingena phezulu kwi-absorption tower ukusuka kwinxalenye ephezulu yombhobho we-casing ukuze igqibezele ukujikeleza kwe-solvent.
Umsinga wegesi eyomileyo ukhutshwa kwicandelo legesi eyomileyo kwindawo yokuphuma kwenqaba yokufunxa, uze ungene kumbhobho wokufudumeza igesi eyomileyo wetanki ye-buffer yokutshintshiselana kobushushu kwicandelo elisezantsi le-TEG reboiler. Emva kokuba ifudunyezwe yi-TEG engenamandla, itsalwa kwi-0.4MPa ngevalvu elawula uxinzelelo oluzisebenzelayo ize ingene kwitanki ye-buffer yegesi yepetroli. Emva kokuba iphumile kwitanki ye-buffer yegesi yepetroli, yahlulwe yaba ziindlela ezimbini, enye yazo ifudunyezwa ize ingene kwicandelo elisezantsi le-buffer yegesi engenamandla njenge-buffer yegesi engenamandla, kwaye enye njenge-buffer yegesi ye-reboiler. Le yinkqubo ye amanzi asusa igesi yendalo.
