Iinkqubo ze-F Ukuphelelwa ngamanzi emzimbeni yi-TEG kwigesi yendalo yindlela eqhelekileyo yokususa amanzi kwigesi yendalo.
Igesi yendalo emanzi emanzi yahlulwe kwiidrophu ezingama-5 μm nangaphezulu ngesixhobo sokwahlula-hlula isihluzo, ize ingene kwigumbi lokwahlula-hlula igesi nolwelo kwicandelo elisezantsi le-triethylene glycol absorption tower yeyunithi yokukhupha amanzi emzimbeni ukuze yahlule ulwelo olukhululekileyo olunokungeniswa kwi-absorption tower xa isixhobo sokwahlula-hlula isihluzo sikwimeko yengozi. Ingena kwicandelo lokungenisa nge-riser ye-absorption tower. I-triethylene glycol ehlaziyiweyo ifakwe phezulu kwe-absorber ukuze iqhagamshelane ngokupheleleyo negesi yendalo esezantsi ukuya phezulu kwi-absorber ukuze idlulisele ubuninzi kwaye itshintshiselwe ukususa amanzi. Igesi yendalo esusiweyo kumswakama isuswa yi-tower top mist catcher ngaphezu kwe-5 μm glycol drops ephuma kwi-tower.
Emva kokuphuma kwinqaba, itshintshiselana ngobushushu ne-glycol eshushu engatyebanga ngaphambi kokuba ingene kwinqaba nge-casing heat exchanger ukunciphisa ubushushu be-triethylene glycol engena kwinqaba. Igesi yendalo emva kokutshintshwa kobushushu ingena kwi-filter separator ukuze yahlule i-glycol ethwalwayo ize ingene kwipayipi yokuthumela ngaphandle. I-triethylene glycol etyebileyo efunxa amanzi kwigesi yendalo iphuma kwinqaba yokufunxa ize ingene kwi-liquid level regulating valve. Emva koxinzelelo, ingena kwipleyiti yokupholisa ye-reflux phezulu kwikholamu ye-liquid distillation etyebileyo, itshintshiselana ngobushushu nomphunga oshushu owenziwe kwi-reboiler, inika amandla okupholisa e-reflux phezulu kwikholamu, ifudunyezwa ukuya kuthi ga kwi-50 ℃, kwaye umbhobho wokuphuma ungena kwi-triethylene glycol flash tank. I-glycol etyebileyo ixinzelelwa ukuya kwi-0.4MPa ~ 0.6MPa kwi-flash tank, kwaye igesi ye-hydrocarbon kunye nezinye iigesi ezinyibilikisiweyo kwi-triethylene glycol ziyacinywa, ezisetyenziswa njengegesi yamafutha yokutsha kwe-reboiler.
I-triethylene glycol etyebileyo ngokukhanyayo ingena kwi-mechanical filter ukuze ihluze ukungcola koomatshini, ize ingene kwi-activated carbon filter ukuze ifunxe ngakumbi ii-hydrocarbons ezinyibilikiswe kwi-triethylene glycol kunye nezinto eziwohlokayo ze-triethylene glycol. Emva koko ingena kwi-plate rich and minor liquid heat exchanger ukuze itshintshise ubushushu nge-triethylene glycol ethambileyo ebushushu obuphezulu evela kwi-heat exchange buffer tank kwinxalenye esezantsi ye-triethylene glycol reboiler. I-heat exchange inyuka iye kwi-120 ~ 130 ℃ kwaye ingene kwi-liquid distillation column etyebileyo.
Kwi-triethylene glycol reboiler esezantsi kwikholamu ye-distillation, i-triethylene glycol ifudunyezwa ukuya kwi-193 ℃, kwaye amanzi kwi-triethylene glycol aqhekezwa aze akhutshwe phezulu kwikholamu ye-distillation ngokusebenzisa i-fractionation kwikholamu ye-distillation. I-Lean glycol enoxinzelelo olumalunga ne-99% (WT) idlula kwikholamu ye-lean liquid stripping kwi-reboiler ukuya kwi-triethylene glycol heat exchange buffer tank esezantsi. Phantsi kwesenzo segesi eyomileyo kwikholamu ye-lean liquid stripping, uxinzelelo lwe-lean glycol engena kwi-heat exchange buffer tank 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-Lean triethylene glycol ipompelwa kwi-gas-liquid heat exchanger ngaphandle kwe-absorber ngepompo, ipholiswe nge-outlet gas heat exchanger, ize ingene phezulu kwe-absorber ukusuka kwinxalenye ephezulu ye-casing ukuze igqibezele ukujikeleza kwe-solvent.
Umsinga wegesi eyomileyo ukhutshwa kwicandelo lombhobho wegesi eyomileyo kwindawo yokuphuma kwe-absorber uze ungene kumbhobho wokufudumeza igesi eyomileyo wetanki ye-heat exchange buffer kwindawo esezantsi ye-triethylene glycol reboiler. Emva kokuba ifudunyezwe yi-lean triethylene glycol, ifakwa kwi-0.4MPa ngevalvu elawula uxinzelelo oluzisebenzelayo ize ingene kwi-fuel gas buffer tank. Emva kokuba iphumile kwi-fuel gas buffer tank, yahlulwe ngeendlela ezimbini. Enye indlela ifudunyezwa ize ingene kwinxalenye esezantsi ye-lean liquid stripping column njenge-lean liquid stripping gas; Enye yi-fuel gas esetyenziswa njenge-reboiler.
