Whakaarohia te nui o te CO2 ki ngā wāhi ka puta ai te waikura.

Me pania ki roto ngā mīhini tango amine me ētahi atu taputapu e ngāwari ana ki te waikura.

Me hanga ngā taputapu hurihuri mai i tētahi kaihanga pono.

2. Whakaahuatanga hangarau tukanga

Ka haere te hau māori mākū kua kukū mā roto i tewehewehe tātarihei wehe i ngā pata wai he 5 μm te rahi, kātahi ka tomo ki te wehewehe hau-wai o te taputapu whakamaroke hei wehe i te wai kore utu. Ka tomo te hau kua wehea ki te wāhanga mimiti mā te paipa hau e piki ake ana o te pourewa mimiti. Ka rehuhia te triethylene glycol kua whakahoutia ki te tihi o te pourewa mimiti, ā, ka whakapā katoatia ki te hau māori mai i raro ki runga i te pourewa mimiti hei kawe i te whakawhiti papatipu me te whakawhiti hei tango i te makuku. Ka tangohia te hau māori kua tangohia te makuku mai i te kaikohi kohu o runga o te pourewa hei tango i ngā pata glycol he nui ake i te 5 μm, kātahi ka puta atu i te pourewa.

I muri i te putanga mai i te pourewa, ka tomo ki roto i te whakawhiti wera o te anga, ka whakawhiti wera ki te glycol wera kikokore i mua i te tomokanga ki te pourewa hei whakaiti i te pāmahana o te triethylene glycol. 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 o waho. Ka rere te triethylene glycol momona kua mimiti i te makuku i roto i te hau māori mai i te pourewa mimiti ka tomo ki te takirere whakahaere taumata wai, ā, i muri i te whakahekenga pēhanga, ka tomo ki te koiri whakamatao reflux i te tihi o te pou whakatikatika wai momona ka whakawhiti wera ki te mamaoa wera i hangaia i roto i te reboiler hei whakarato reflux o runga pou. I muri i te whakarato i te kaha whakamatao reflux o runga pou, ka whakamahanahia ki te 50 ℃, kātahi ka puta mai i te koiri ki te tāke mura triethylene glycol. Ka whakahekehia te glycol momona ki te 0.4mpa~0.6mpa i roto i te tāke mura, ā, ka tukuna atu te hau hauwai me ētahi atu hau kua rewa i roto i te triethylene glycol, ā, ka whakamahia tēnei wāhanga o te hau hei hau wahie mō te tahu reboiler.

Ka tomo te wai momona triethylene glycol kua whakakāhia ki te tātari ā-ringa hei tātari i ngā poke ā-ringa, kātahi ka tomo ki te tātari waro whakahohe hei mimiti atu i ngā matū warowaihā kua rewa i roto i te triethylene glycol me ngā matū kua pakaru o te triethylene glycol. Kātahi ka tomo ki te whakawhiti wera wai momona-momo pereti, ka whakawhiti wera ki te triethylene glycol momona pāmahana-tiketike mai i te tāke ārai whakawhiti wera kei te wāhanga o raro o te kohua hou triethylene glycol, ā, ka wera ake ki te ~150 °C hei tomo ki te pou whakatikatika wai momona.

I roto i te kohua hou o te triethylene glycol i te pito o raro o te pou whakatikatika, ka whakamahanahia te triethylene glycol ki te 193 ℃, ā, ka wehewehea te wai i roto i te triethylene glycol ka tukuna mai i te tihi o te pou whakatikatika mā te pānga wehewehenga o te pou whakatikatika. 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 glycol kikokore e tomo ana ki te tāke ārai whakawhiti wera te eke ki te 99.5%~99.8%.

I roto i te tāke glycol buffer, ka tomo te glycol kikokore me te pāmahana o te 193 °C ki te whakawhiti wera glycol kikokore hei whakawhiti wera ki te glycol momona, ā, ka heke te pāmahana ki te 100 °C ka tomo ki te papu. Ka papua te triethylene glycol wai kikokore ki roto i te whakawhiti wera hau-wai i waho o te pourewa mimiti, ā, 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 taha o runga o te anga hei whakaoti i te rere o te whakarewa.

Ko te hau maroke e tangohia ana mai i te wāhanga paipa hau maroke i te putanga o te pourewa mimiti, ko te hau tango i te pou whakatika.
