Ngā Tukanga o Te maroketanga o te TEG i roto i te hau māori he huarahi noa ki te tango i te wai i roto i te hau maori.
Ka wehea te hau māori mākū kua mākū mai i ngā pata 5 μm me runga ake mā te wehewehe tātari, kātahi ka tomo ki te rūma wehewehe hau-wai i te wāhanga o raro o te pourewa mimiti triethylene glycol o te wāhanga whakamaroke hei wehe i te wai kore utu ka kawea mai ki te pourewa mimiti ina he aituā te wehewehe tātari. Ka tomo ki te wāhanga mimiti mā te ara o te pourewa mimiti. Ka werohia te triethylene glycol kua whakahoutia ki te tihi o te mimiti kia tino pā atu ki te hau māori mai i raro ki runga i te mimiti hei whakawhiti papatipu me te whakawhiti hei tango i te wai. Ka tangohia te hau māori kua tangohia te makuku e te hopu kohu o runga o te pourewa mō te neke atu i te 5 μm pata glycol i waho o te pourewa.
I muri i te wehenga atu i te pourewa, ka whakawhiti wera ki te glycol wera kikokore i mua i te urunga ki te pourewa mā te whakawhiti wera o te anga hei whakaiti i te pāmahana o te triethylene glycol 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 ka haria, kātahi ka tomo ki te paipa kaweake. Ka rere te triethylene glycol whai rawa e mimiti ana i te wai i roto i te hau māori i waho o te pourewa mimiti ka tomo ki te takirere whakahaere taumata wai. I muri i te whakahekenga pēhanga, ka tomo ki te pereti whakamatao reflux i runga i te pou whakamātao wai whai rawa, ka whakawhiti wera ki te mamaoa wera i hangaia i roto i te reboiler, ka whakarato i te kaha whakamatao reflux i runga i te pou, ka whakamahanahia ki te 50 ℃, ā, ka tomo te paipa putanga ki te tāke mura triethylene glycol. Ka whakahekehia te glycol whai rawa ki te 0.4MPa ~ 0.6MPa i roto i te tāke mura, ā, ka tukuna te hau hauwai me ētahi atu hau i rewa i roto i te triethylene glycol, ka whakamahia hei hau wahie mō te tahu o te reboiler.
Ka tomo te triethylene glycol wai momona-tere ki te tātari miihini hei tātari i ngā poke miihini, kātahi ka tomo ki te tātari waro whakahohe hei mimiti atu i ngā warowaihā kua rewa i roto i te triethylene glycol me ngā matū pirau o te triethylene glycol. Kātahi ka tomo ki te whakawhitinga wera wai momona-pereti me te wai ngoikore-pereti hei whakawhiti wera ki te triethylene glycol kikokore pāmahana-tiketike mai i te tāke ārai whakawhiti wera kei te wāhanga o raro o te kohua hou o te triethylene glycol. Ka piki te whakawhiti wera ki te 120 ~ 130 ℃ ka tomo ki te pou whakatō wai momona.
I roto i te kohua hou o te triethylene glycol i te pito o raro o te pou whakatō, ka whakamahanahia te triethylene glycol ki te 193 ℃, ā, ka wehea te wai i roto i te triethylene glycol ka tukuna mai i te tihi o te pou whakatō mā te wehewehenga o te pou whakatō. Ka puea ake te glycol kikokore me te kukū o te 99% (WT) mai i te pou tango wai kikokore i roto i te kohua hou ki te tāke ārai whakawhiti wera triethylene glycol o raro. 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 ārai 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 ki te whakawhiti wera ki te glycol momona. Ina heke te pāmahana ki te 100 ℃, ka tomo ki te papu. Ka pupuhihia te triethylene glycol kikokore ki roto i te whakawhiti wera hau-wai i waho o te ngongo e te papu, ka whakamataohia e te whakawhiti wera hau putanga, kātahi ka tomo ki te tihi o te ngongo mai i te taha o runga o te anga hei whakaoti i te rere o te whakarewa.
Ka puta mai he awa hau maroke mai i te wāhanga paipa hau maroke i te putanga o te ngongo ka tomo ki te paipa whakamahana hau maroke o te tāke ārai whakawhiti wera i te pito o raro o te kohua hou triethylene glycol. I muri i te whakamahanatanga e te triethylene glycol kikokore, ka whakaitihia ki te 0.4MPa mā te takirere whakahaere pēhanga whaiaro ka tomo ki te tāke ārai hau wahie. I muri i te putanga mai i te tāke ārai hau wahie, ka wehea kia rua ngā ara. Ko tētahi ara ka whakamahanatia ka tomo ki te pito o raro o te pou tango wai kikokore hei hau tango wai kikokore; ko tētahi ko te hau wahie e whakamahia ana hei kohua hou.
