Nga tukanga oFTEG matewai i roto i te hau maorihe huarahi noa ki te tango i te wai i roto i te hau maori.
Ka wehea te hau makuku makutu mai i nga rūrūtia 5μm me runga ake i roto i te whakawehe tātari katahi ka uru ki te ruuma wehenga hau-wai i te taha o raro o te pourewa whakauru triethylene glycol o te wae whakamakuku hei wehe i te wai kore utu ka kawea mai ki roto. te pourewa absorption ka he te whakawehe tātari i roto i te āhua aituā. Ka uru ki roto i te waahanga whakaurunga na roto i te riser o te pourewa absorption. Ko te triethylene glycol kua whakahouhia ka werohia ki te tihi o te kaihoroi kia tino pa atu ki te hau o raro-runga i runga i te kaihoroi mo te whakawhiti papatipu me te whakawhiti ki te tango wai. Ko te hau makuku kua tangohia ka tangohia e te kaikawe kohu o runga o te pourewa mo te neke atu i te 5 μm nga pata glycol mai i te pourewa.
I muri i te wehe atu i te pourewa, ka whakawhitia te wera ki te glycol hiroki wera i mua i te kuhu ki te pourewa ma te kaitahuri wera casing hei whakaiti i te pāmahana o te triethylene glycol ka uru ki te pourewa. Ko te hau maori i muri i te whakawhiti wera ka uru ki te whakawehe tātari hei wehe i te glycol ka mauria ka uru ki te paipa kaweake. Ko te taonga nui o te triethylene glycol e mimiti ana i te wai i roto i te hau maori ka rere ki waho o te pourewa absorption, ka uru ki roto ki te reera taumata wai. I muri i te whakahekenga, ka uru ki roto i te pereti whakamahana rewharewha ki te tihi o te pou whakamahana wai nui, ka whakawhiti i te wera me te mamaoa wera i hangaia i roto i te reboiler, ka whakarato i te kaha whakamahana reflux ki runga o te pou, ka wera ki te 50 ℃, a ka uru te paipa puta ki roto i te taika hiko triethylene glycol. Ko te glycol taonga ka whakahekehia ki te 0.4MPa ~ 0.6MPa i roto i te tank hiko, a ko te hau waiwaro me etahi atu hau ka rewa i roto i te triethylene glycol ka puta ki waho, ka whakamahia hei hau wahie mo te wera o te reboiler.
Ka kuhu te triethylene glycol wai nui ki te tātari miihini ki te tarai i nga poke miihini, katahi ka uru ki te tātari waro whakahohe hei whakauru atu i nga warowaiwai kua rewa i roto i te triethylene glycol me nga matū whakaheke o te triethylene glycol. Katahi ka uru atu ki roto i te pereti kaikawe me te koretake o te wera wai hei whakawhiti i te wera me te triethylene glycol hiroki teitei-te pawera mai i te tank whakawhiti wera i te taha o raro o te triethylene glycol reboiler. Ka piki te whakawhitinga wera ki te 120 ~ 130 ℃ ka uru ki roto i te pou whakakoi wai nui.
I roto i te reboiler triethylene glycol i te taha o raro o te pou whakamaaratanga, ka whakamahanahia te triethylene glycol ki te 193 ℃, ka hautauhia te wai i roto i te triethylene glycol ka tukuna mai i te tihi o te pou whakamarumaru na roto i te hautanga o te pou whakamaoritanga. Ko te glycol hiroki me te kukū tata ki te 99% (WT) ka puhake mai i te tīwae tihorea wai hiroki i roto i te paera ki te taika whakawhiti wera triethylene glycol raro. I raro i te mahi o te hau maroke i roto i te tīwae tihorea wai hiroki, te kukū o te glycol hiroki tomo ki te whakawhiti wera tank pūreirei taea tae 99.5% ~ 99.8%.
I roto i te tank buffer glycol, ko te glycol hiroki me te pāmahana o te 193 ℃ ka uru ki roto ki te kaihuri wera glycol taonga me te rawakore ki te whakawhiti wera ki te glycol taonga. Ka heke te pāmahana ki te 100 ℃, ka uru ki roto i te papu. Ka pupuhihia te triethylene glycol ki roto i te whakawhiti wera hau-wai i waho o te kaihoroi ma te papu, ka whakamataohia ki te putanga wera hau hau, katahi ka kuhu ki te tihi o te kaihoroi mai i te pito o runga o te pouaka ki te whakaoti i te tohanga whakarewa.
Ko te rere o te hau maroke ka puta mai i te waahanga putorino hau maroke i te putanga o te kaihoroi ka uru ki roto ki te putorino whakamahana hau maroke o te tank whakawhiti wera i te taha o raro o te triethylene glycol reboiler. Whai muri i te whakamahana e te triethylene glycol hiroki, ka werohia ki te 0.4MPa na roto i te riipene whakahaere pehanga ka uru ki roto i te taika whakaahuru wahie. I muri i te wehe atu i te tank hau hinu, ka wehea kia rua nga huarahi. Ko tetahi ara ka whakamahana ka uru ki te taha o raro o te tiihi tihorea wai hiroki hei hau tihorea wai hiroki; Ko tetahi atu ko te hau wahie e whakamahia ana hei reboiler.
