Ka wehea te hau māori mākū i te āhua kukū e te wehewehe tātari hei wehe i ngā pata wai o te 5 μm me runga ake, kātahi ka tomo ki te rūma wehewehe hau-wai i te wāhanga o raro o Pourewa mimiti TEG (Triethylene gly) o wāhanga whakamaroke hei wehe i te wai kore utu ka kawea mai ki roto i te pourewa mimiti ina kei roto te wehewehe tātari i te āhua aituā. Tomohia te wāhanga mimiti mā te pū whakarunga o te pourewa mimiti. Ka papua te TEG kua whakahoutia ki te tihi o te pourewa mimiti kia tino pā atu ki te hau māori mai i raro ki runga i te pourewa mimiti hei whakawhiti papatipu me te tango makuku. Ka tukuna te hau māori maroke mai i te pourewa i muri i te tango i te neke atu i te 5 μ m pata glycol mā te hopu kohu o runga o te pourewa.
I muri i te wehenga atu i te pourewa, ka whakawhitihia te wera ki te glycol wera kikokore i mua i te urunga ki te pourewa mā te whakawhiti wera ngongo hei whakaiti i te pāmahana o te TEG e tomo ana ki te pourewa. I muri i te whakawhiti wera, ka tomo te hau māori ki te wehewehe tātari hei wehe i te glycol kawe, kātahi ka tomo ki te paipa kaweake. Ko te TEG momona, e mimiti ana i te makuku i roto i te hau māori, ka rere atu i te pourewa mimiti ka tomo ki te takirere whakahaere taumata wai. I muri i te whakahekenga pehanga, ka tomo ki te pereti whakamatao reflux i runga i te pou whakamātao wai momona hei whakawhiti wera me te mamaoa wera i hangaia i roto i te reboiler. I muri i te whakarato i te kaha whakamatao reflux o te tihi pou, ka whakamahanahia te TEG momona ki te 50 ℃. Ka tomo te ngongo putanga ki te tāke mura TEG. Ka whakahekehia te glycol momona ki te 0.4MPa ~ 0.6MPa i roto i te tāke mura. Ka tukuna atu te hau hauwaiwaro me ētahi atu hau i rewa i roto i te TEG, ā, ka whakamahia ēnei hau hei hau wahie mō te tahu reboiler.
I muri i te whakakoi, ka tomo te wai TEG momona ki te tātari miihini hei tātari i ngā poke miihini, kātahi ka tomo ki te tātari waro whakahohe hei mimiti atu i ngā matū warowaihā kua rewa i roto i te TEG me ngā matū pirau o te TEG. Kātahi ka tomo ki te whakawhiti wera wai momona me te wai rawakore momo pereti hei whakawhiti wera ki te TEG hiroki pāmahana teitei mai i te tāke ārai whakawhiti wera o raro o te kohua hou TEG. Ka piki te pāmahana whakawhiti wera ki te 120 ~ 130 ℃ ka tomo ki te pou whakatō wai momona.
I roto i te kohua hou TEG i raro i te pou whakatō, ka whakamahanahia te TEG ki te 193 ℃, ā, ka wehea te wai i roto i te TEG ka tukuna mai i te tihi o te pou whakatō. Ko te kukū o te 99% (WT) o te glycol kikokore ka ringihia ki roto i te tāke whakapūmau whakawhiti wera TEG o raro e te pou tango wai kikokore i roto i te kohua hou. I raro i te mahi a te hau maroke i roto i te pou tango wai kikokore, ka taea e te kukū o te glycol kikokore e tomo ana ki te tāke whakapūmau whakawhiti wera te eke ki te 99.5% ~ 99.8%.
I roto i te tāke parenga glycol, ka tomo te glycol kikokore me te pāmahana o te 193 ℃ ki te whakawhiti wera glycol momona me te glycol rawakore hei whakawhiti wera ki te glycol momona. Ina heke te pāmahana ki te 100 ℃, ka tomo ki te papu. Ka papuhia te wai TEG kikokore ki roto i te whakawhiti wera hau-wai o waho o te pourewa mimiti mā te papu. I muri i te whakamatao me te whakawhiti wera hau i waho o te pourewa, ka tomo ki te tihi o te pourewa mimiti mai i te pito o runga o te paipa anga hei whakaoti i te rere o te whakarewa.
Ka puta he awa hau maroke mai i te wāhanga hau maroke i te putanga o te pourewa mimiti, ka tomo ki te paipa whakamahana hau maroke o te tāke ārai whakawhiti wera i te taha raro o te kohua hou TEG. Whai muri i te whakamahanatanga e te TEG kikokore, ka whakaitihia ki te 0.4MPa e te takirere whakahaere pēhanga whaiaro, kātahi ka tomo ki te tāke ārai hau wahie. Whai muri i te putanga mai i te tāke ārai hau wahie, ka wehea kia rua ngā ara, ko tētahi ka whakamahanatia ka tomo ki te taha raro o te pou tango wai kikokore hei hau tango wai kikokore, ko tētahi hei hau wahie o te kohua hou. Koinei te tukanga mō te tango wai i te hau māori.
