Ukwethulwa kwenqubo yesitshalo sokuphelelwa amanzi emzimbeni se-TEG esivikelweni sokwelapha igesi yemvelo
Indlela yokumunca i-solvent ingenye yezindlela ezisetshenziswa kakhulu inqubo yokuphelelwa amanzi emzimbeni embonini yokucubungula igesi yemvelo, Ukuphelelwa amanzi emzimbeni kwe-TEG (ukuphelelwa amanzi emzimbeni kwe-triethylene glycol) kuvame ukusetshenziswa njengohlobo lwe-Solvent. Isebenzisa isimiso sokumunca futhi isebenzisa izinto ze-glycol (njenge-triethylene glycol) njengezimunca ukuze zixhumane ngokugcwele negesi yemvelo, zidlulisele amanzi ku-solvent ukuze kufezwe ukuphelelwa amanzi emzimbeni.
Ngemva kokuphuma embhoshongweni, ingena emshinini wokushintshanisa ukushisa bese ishintshanisa ukushisa ne-glycol eshisayo engangeni ngaphambi kokungena embhoshongweni ukuze kuncishiswe izinga lokushisa le-TEG. Igesi yemvelo ngemva kokushintshanisa ukushisa ingena esihlukanisi sesihlungi ukuze ihlukanise i-glycol ethwalwayo bese ingena epayipini langaphandle. I-TEG ecebile emunce umswakama kugesi yemvelo iphuma embhoshongweni wokumunca bese ingena ku-valve elawula izinga loketshezi, futhi ngemva kokunciphisa ukucindezeleka, ingena ekhoyilini yokupholisa ye-reflux phezulu kwekholomu yokulungisa uketshezi olucebile bese ishintshanisa ukushisa nomoya oshisayo okhiqizwa ku-reboiler ukuze inikeze i-reflux ephezulu yekholomu. Ngemva kokunikeza amandla okupholisa e-reflux ephezulu yekholomu, ishiswa cishe ku-50 ℃, bese iphuma ekhoyilini iye ethangini le-TEG flash. I-glycol ecebile icindezelwa ibe ngu-0.4mpa~0.6mpa ethangini le-flash, bese igesi ye-hydrocarbon namanye amagesi ancibilikisiwe ku-TEG ayakhishwa, futhi le ngxenye yegesi isetshenziswa njengegesi kaphethiloli yokushiswa kwe-reboiler.
I-TEG ewuketshezi olucebile olukhanyayo ingena esihlungini somshini ukuze ihlunge ukungcola komshini, bese ingena esihlungini sekhabhoni esisebenzayo ukuze imunce izinto ze-hydrocarbon ezincibilikisiwe ku-TEG kanye nezinto eziwohlokile ze-TEG. Bese ingena esishintshini sokushisa soketshezi olunamafutha aphansi, ishintshane ngokushisa ne-TEG enamafutha aphansi eshisayo evela ethangini lokushintshanisa ukushisa engxenyeni engezansi ye-TEG reboiler, bese ishisa kuze kufike ku-~150 °C ukuze ingene kukholomu yokulungisa uketshezi olucebile.
Ku-TEG reboiler engxenyeni engezansi yekholomu yokulungisa, i-TEG ishiswa ku-193 ℃, bese amanzi aku-TEG ehlukaniswa futhi akhishwe phezulu kwekholomu yokulungisa ngomphumela wokuhlukaniswa kwekholomu yokulungisa. I-lean glycol enokugxila okungaba ngu-99% (wt) igcwala kusukela kukholomu yokususa uketshezi oluthambile ku-reboiler iye ethangini lokushintshanisa ukushisa le-TEG elingezansi. Ngaphansi kwesenzo segesi eyomile kukholomu yokususa uketshezi oluthambile, ukugxilwa kwe-lean glycol okungena ethangini lokususanisa ukushisa kungafinyelela ku-99.5% ~ 99.8%.
Ethangini le-glycol buffer, i-lean glycol enokushisa okungaba ngu-193 °C ingena ku-lean-rich glycol heat exchanger ukuze ishintshane ngokushisa ne-glycol ecebile, bese izinga lokushisa lehla lifike ku-100 °C bese lingena ephampini. I-lean liquid TEG iphonswa ku-gas-liquid heat exchanger ngaphandle kombhoshongo wokumunca, futhi ngemva kokupholisa nge-gas heat exchanger iphuma embhoshongweni, ingena phezulu kombhoshongo wokumunca kusuka engxenyeni engenhla ye-casing ukuze iqedele ukujikeleza kwe-solvent.
