Igesi yendalo esandula ukukhutshwa emthonjeni idla ngokuzaliswa ngumphunga wamanzi ogcweleyo, onokubangela ingozi enkulu. Igesi yendalo enezinto ezine-asidi inokuba ne-asidi yokubola kwemibhobho nezixhobo xa kukho amanzi; Ukufuma kunokunciphisa amandla okuthutha imibhobho yegesi yendalo kwaye kubangele ukusetyenziswa kwamandla okungeyomfuneko. Ke ngoko, ukuphelelwa ngamanzi emzimbeni ngegesi yendalo iyimfuneko kakhulu.
Ukuphelelwa ngamanzi emzimbeni ngegesi yendalo yinkqubo esebenzisa iindlela ezithile zokususa umphunga wamanzi agcweleyo kwigesi yendalo. Iindlela eziqhelekileyo ziquka ukuphelelwa ngamanzi emzimbeni ngokuphola, ukufunxwa kwe-solvent, ukuphelelwa ngamanzi emzimbeni okufunxa amanzi okuqinileyo, ukuphelelwa ngamanzi emzimbeni, njl. Iindlela ezahlukeneyo zokuphelelwa ngamanzi emzimbeni zineempawu zazo kwaye zifanelekile kwiindawo ezahlukeneyo.
Inkqubo ephambili ye-triethylene glycol yile ilandelayo:
Igesi yendalo emanzi xa ikwimeko yokugcwala yahlulwe yisihluzo sokwahlulahlula amathontsi olwelo angama-5 μ m nangaphezulu, ize ingene kwigumbi lokwahlulahlula igesi nolwelo kwicandelo elisezantsi le-triethylene glycol absorption tower yeyunithi yokuphelelwa ngamanzi ukuze yahlule ulwelo olukhululekileyo olunokungeniswa kwinqaba yokufunxa xa i-filter separator ikwimeko yengozi. Ngena kwicandelo lokufunxa nge-riser yenqaba yokufunxa. I-triethylene glycol 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 amathontsi e-glycol angaphezu kwama-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-triethylene glycol engena kwinqaba. Emva kokutshintshwa kobushushu, igesi yendalo ingena kwi-filter separator ukuze yahlule i-carrier glycol ize ingene kwi-export pipeline. I-triethylene glycol (TEG) etyebileyo, efunxa umswakama kwigesi yendalo, iphuma kwi-absorption tower ize ingene kwi-liquid level control valve. Emva kokunciphisa uxinzelelo, 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-triethylene glycol etyebileyo ifudunyezwa ukuya kuthi ga kwi-50 ℃. Ityhubhu yokuphuma ingena kwi-TEG flash tank. I-rich glycol iyancipha uxinzelelo ukuya 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.
