Te tukanga whakauru i te tipu whakamaroketanga TEG ki roto i te paheke maimoatanga hau maori

Ko te tikanga mimiti whakarewa tētahi o ngā tikanga e whakamahia whānuitia ana tukanga whakamaroke i roto i te umanga tukatuka hau māori, Te matewai o TEG Ko te (whakamaroketanga o te triethylene glycol) he momo whakarewa e whakamahia ana. Ka whakamahia te mātāpono mimiti, ā, ka whakamahia ngā matū glycol (pērā i te triethylene glycol) hei mimiti hei whakapā atu ki te hau māori, ka whakawhiti i te wai ki te whakarewa hei whakatutuki i te whakamaroketanga.

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 TEG. 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 TEG 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 TEG. 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 TEG, ā, ka whakamahia tēnei wāhanga o te hau hei hau wahie mō te tahu reboiler.

Ka tomo te wai TEG whai kiko 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 TEG me ngā matū kua pakaru o te TEG. Kātahi ka tomo ki te whakawhiti wera wai whai kiko momo pereti, ka whakawhiti wera ki te TEG whai kiko pāmahana teitei mai i te tāke ārai whakawhiti wera kei te wāhanga o raro o te kohua hou TEG, ā, ka wera ake ki te ~150 °C hei tomo ki te pou whakatikatika wai whai kiko.

I roto i te kohua hou TEG i te pito o raro o te pou whakatikatika, 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 whakatikatika mā te pānga wehewehenga o te pou whakatikatika. Ka puea ake te glycol hiroki me te kukū o te 99% (wt) mai i te pou tango wai hiroki i roto i te kohua hou ki te tāke ārai whakawhiti wera TEG o raro. I raro i te mahi a te hau maroke i roto i te pou tango wai hiroki, ka taea e te kukū glycol hiroki 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 °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 wai TEG 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.
