Izinqubo ze-F Ukuphelelwa amanzi emzimbeni kwe-TEG kugesi yemvelo kuyindlela evamile yokususa amanzi kugesi yemvelo.
Igesi yemvelo emanzi egcwele ihlukaniswa ngamaconsi angu-5 μm nangaphezulu ngesihlukanisi sesihlungi bese ingena ekamelweni lokuhlukanisa igesi noketshezi engxenyeni engezansi yombhoshongo wokumunca i-triethylene glycol weyunithi yokuphelelwa amanzi ukuze ihlukanise uketshezi olukhululekile olungalethwa embhoshongweni wokumunca lapho isihlukanisi sesihlungi sisesimweni sengozi. Ingena esigabeni sokumunca nge-riser yombhoshongo wokumunca. I-triethylene glycol evuselelwe ifakwe phezulu kwesimunca ukuze ixhumane ngokugcwele negesi yemvelo engezansi-phezulu kummunca ukuze kudluliselwe ngobuningi futhi kushintshwe ukuze kususwe amanzi. Igesi yemvelo esusiwe umswakama isuswa yi-tower top mist catcher isikhathi esingaphezu kwama-5 μm amaconsi e-glycol aphuma embhoshongweni.
Ngemva kokuphuma embhoshongweni, ishintshana ngokushisa ne-glycol eshisayo engangeni ngaphambi kokungena embhoshongweni nge-casing heat exchanger ukuze kuncishiswe izinga lokushisa le-triethylene glycol engena embhoshongweni. Igesi yemvelo ngemva kokushintshana ngokushisa ingena kwisihlukanisi sesihlungi ukuze ihlukanise i-glycol ethwalwayo bese ingena epayipini lokuthumela ngaphandle. I-triethylene glycol ecebile emunca amanzi egesini yemvelo iphuma embhoshongweni wokumunca bese ingena ku-valve elawula izinga loketshezi. Ngemva kokunciphisa ukucindezeleka, ingena epuletini lokupholisa le-reflux phezulu kwekholomu yokuncibilikisa uketshezi olucebile, ishintshana ngokushisa nomoya oshisayo okhiqizwa ku-reboiler, ihlinzeka ngomthamo wokupholisa we-reflux phezulu kwekholomu, ishiswa cishe ku-50 ℃, bese ipayipi lokukhipha lingena ethangini le-triethylene glycol flash. I-glycol ecebile icindezelwa ibe ngu-0.4MPa ~ 0.6MPa ethangini le-flash, bese igesi ye-hydrocarbon namanye amagesi ancibilikisiwe ku-triethylene glycol ayakhishwa, asetshenziswa njengegesi kaphethiloli yokushiswa kwe-reboiler.
I-triethylene glycol ewuketshezi olucebile nge-flash ingena esihlungini somshini ukuze ihlunge ukungcola komshini, bese ingena esihlungini se-carbon esisebenzayo ukuze imunce ama-hydrocarbon ancibilikisiwe ku-triethylene glycol kanye nezinto eziwohlokayo ze-triethylene glycol. Bese ingena esitsheni esinoketshezi olucebile nolubi lokushisa ukuze ishintshane ngokushisa ne-triethylene glycol ethambile eshisayo evela ethangini le-heat exchange buffer engxenyeni engezansi ye-triethylene glycol reboiler. I-heat exchange ikhuphukela ku-120 ~ 130 ℃ bese ingena kukholomu ye-liquid distillation ecebile.
Ku-triethylene glycol reboiler engxenyeni engezansi yekholomu yokuhluza, i-triethylene glycol ishiswa kufikela ku-193 ℃, bese amanzi aku-triethylene glycol ahlukaniswa futhi akhishwe phezulu kwekholomu yokuhluza ngokusebenzisa ukuhlukaniswa kwekholomu yokuhluza. I-Lean glycol enokugcwala okungaba ngu-99% (WT) igcwala kusukela kukholomu yokuhluza uketshezi oluthambile ku-reboiler iye ethangini elingaphansi le-triethylene glycol heat exchange buffer. Ngaphansi kwesenzo segesi eyomile kukholomu yokuhluza uketshezi oluthambile, ukugcwala kwe-lean glycol engena ethangini lokuhluza ukufudumala kungafinyelela ku-99.5% ~ 99.8%.
Ethangini le-glycol buffer, i-glycol engenamandla enokushisa okungaba ngu-193 ℃ ingena ku-glycol heat exchanger ecebile nembi ukuze ishintshane ngokushisa ne-glycol ecebile. Lapho izinga lokushisa lehla laya cishe ku-100 ℃, lingena ku-pump. I-triethylene glycol engenamandla iphonswa ku-gas-liquid heat exchanger ngaphandle kwe-absorber nge-pump, ipholiswe nge-outlet gas heat exchanger, bese ingena phezulu kwe-absorber isuka engxenyeni engenhla ye-casing ukuze iqedele ukujikeleza kwe-solvent.
Umfudlana wegesi eyomile uholwa uphume engxenyeni yepayipi legesi eyomile endaweni yokuphuma kwe-absorber bese ungena epayipini lokushisa legesi eyomile yethangi le-heat exchange buffer engxenyeni engezansi ye-triethylene glycol reboiler. Ngemva kokufudunyezwa yi-lean triethylene glycol, iphonswa ku-0.4MPa nge-valve elawula ukucindezela ezisebenzela yona bese ungena ethangini le-fuel gas buffer. Ngemva kokuphuma ethangini le-fuel gas buffer, ihlukaniswe ngezindlela ezimbili. Enye indlela iyafudunyezwa bese ingena engxenyeni engezansi yekholomu ye-lean liquid stripping njengegesi ye-lean liquid stripping; Enye igesi ye-fuel esetshenziswa njenge-reboiler.
