2. Incazelo yobuchwepheshe benqubo

Igesi yemvelo emanzi egcwele idlula endaweniisihlukanisi sesihlungi ukuhlukanisa amaconsi angu-5 μm nangaphezulu, bese kungena isihlukanisi se-gas-liquid sedivayisi yokukhipha amanzi ukuze sihlukanise uketshezi lwamahhala. Igesi ehlukanisiwe ingena esigabeni sokumuncwa ngepayipi elikhuphukayo legesi lombhoshongo wokumuncwa. I-triethylene glycol evuselelwe kabusha ifafazwa phezulu kombhoshongo wokumunca, futhi ixhunywe ngokugcwele negesi yemvelo kusukela phansi kuya phezulu kumbhoshongo wokumunca ukuze kwenziwe ukudluliswa okukhulu nokushintshaniswa ukuze kususwe umswakama. Igesi yemvelo okususiwe umswakama ikhishwa kumbhoshongo oqoqiwe wenkungu ukuze kukhishwe amaconsi e-glycol amakhulu kuno-5 μm bese iphuma embhoshongweni.

Ngemva kokuphuma embhoshongweni, ingena ku-casing heat exchanger bese ishintshanisa ukushisa ne-hot lean glycol ngaphambi kokungena embhoshongweni ukuze kuncishiswe izinga lokushisa le-triethylene glycol. Igesi yemvelo ngemva kokushintshana kokushisa ingena kusihlukanisi sokuhlunga ukuze ihlukanise i-glycol ephethwe bese ingena epayipini langaphandle. I-triethylene glycol ecebile emunce umswakama wegesi yemvelo iphuma embhoshongweni wokumuncwa futhi ingene kuvalvu elawula uketshezi, futhi ngemva kokucindezeleka, ingena kukhoyili yokupholisa i-reflux phezulu kwekholomu yokulungiswa koketshezi olucebile futhi ishintshisane ngokushisa nayo. umusi oshisayo okhiqizwe ku-reboiler ukunikeza ikholomu phezulu reflux. Ngemva kokunikeza umthamo wokupholisa wekholomu ephezulu ye-reflux, ifudunyezwa ifike ku-50 ℃, bese iphuma kukhoyili iye ethangini le-triethylene glycol flash.I-glycol ecebile icindezeleka ibe ngu-0.4mpa ~ 0.6mpa ku-flash tank, kanye ne-hydrocarbon. igesi kanye namanye amagesi ancibilikisiwe ku-triethylene glycol kuyakhanya, futhi le ngxenye yegesi isetshenziswa njengegesi kaphethiloli yokuvutha kabusha kwe-reboiler.

I-triethylene glycol ewuketshezi ecwebezelayo ingena kusihlungi esisebenza ngomshini ukuze ihlunge ukungcola kwemishini, bese ingena kusihlungi sekhabhoni esicushiwe ukuze siqhubeke nokukhanga izinto ze-hydrocarbon ezincibilike ku-triethylene glycol kanye nezinto ezonakele ze-triethylene glycol. Bese ingena emshinini wokushisa owuketshezi ocebile onamapuleti, ishintshisane ngokushisa okuphezulu ne-lean triethylene glycol esezingeni eliphezulu ukusuka ethangini lebhafa lokushintsha ukushisa engxenyeni engezansi ye-triethylene glycol reboiler, bese ishisa kufika ku-~150 °C ukuze ingene. ikholomu ecebile yokulungisa uketshezi.

Ku-triethylene glycol reboiler engxenyeni engezansi yekholomu yokulungiswa, i-triethylene glycol ishiselwa ku-193 ℃, futhi amanzi ku-triethylene glycol ahlukaniswa futhi akhishwe kusukela phezulu kwekholomu yokulungisa ngokusebenzisa umphumela wokuhlukaniswa kwekholomu yokulungisa. I-lean glycol ene-concentration engaba ngu-99% (wt) ichichima ukusuka kukholomu yokuhlubula uketshezi oluncane ku-reboiler kuya ethangini eliphansi le-triethylene glycol lokushintsha ukushisa. Ngaphansi kwesenzo segesi eyomile kukholamu yokuhlubula uketshezi oluthambile, ukugxiliswa kwe-glycol ethambile engena ethangini lesigcinalwazi sokushintsha ukushisa kungafinyelela ku-99.5%~99.8%.

Ethangini le-glycol buffer, i-lean glycol enezinga lokushisa elingaba ngu-193 °C ingena emshinini wokushisa we-glycol ocebile ukuze ishintshisane ngokushisa ne-glycol ecebile, futhi izinga lokushisa lehla lifike cishe ku-100 °C bese lingena empompini. Uketshezi oluthambile lwe-triethylene glycol luphonswa kusishintshi sokushisa okuwuketshezi lwegesi ngaphandle kombhoshongo wokumuncwa, futhi ngemva kokupholisa ngesishintshi sokushisa kwegesi ngaphandle kombhoshongo, lungena phezulu kombhoshongo wokumunca lusuka engxenyeni engenhla yebhokisi ukuze luqedele ukujikeleza kwe-solvent.

Igesi eyomile ekhishwa engxenyeni yepayipi legesi elomile lapho kuphuma khona umbhoshongo wokumuncwa igesi yokukhumula yekholomu yokulungisa.
