Ko nga taputapu hurihuri me ahu mai i tetahi kaihanga pono.
2. Tukatuka hangarau whakaahuatanga
Ka haere te hau makuku makutu i roto i tewhakawehe tātari ki te wehe i nga pata o te 5 μm me runga ake, ka uru ki te whakawehe hau-wai o te taputapu whakaheke wai hei wehe i te wai kore utu. Ko te hau kua wehea ka uru ki te wahanga absorption i roto i te putorino piki hau o te pourewa absorption. Ko te triethylene glycol kua whakahouhia ka mapuhia ki te tihi o te pourewa absorption, a ka tino whakapiri atu ki te hau taiao mai i raro ki runga i te pourewa absorption ki te kawe i te whakawhitinga papatipu me te whakawhiti ki te tango i te makuku. Ko te hau maori kua tangohia te makuku ka tangohia mai i te kaikohi kohu o runga o te pourewa ki te tango i nga pata glycol nui ake i te 5 μm ka puta atu i te pourewa.
I muri i te putanga atu i te pourewa, ka uru atu ki roto i te kaitahuri wera me te whakawhiti wera me te glycol hiroki wera i mua i te urunga ki te pourewa hei whakaiti i te pāmahana o te triethylene glycol. Ko te hau maori i muri i te whakawhiti wera ka uru ki te whakawehe tātari hei wehe i te glycol e mauria ana ka uru ki te paipa o waho. Ko te triethylene glycol taonga kua mau i te makuku i roto i te hau maori ka rere mai i te pourewa absorption ka uru ki roto ki te riipene whakahaere taumata wai, a, i muri i te paheketanga, ka uru atu ki roto i te reera whakamatao i te tihi o te pou whakatikatika wai nui me te whakawhiti wera me te te mamaoa wera i hangaia i roto i te reboiler hei whakarato i te rerenga o runga o te pou. I muri i te whakarato i te kaha o te hauhautanga reflux o runga, ka wera ki te 50 ℃, ka puta ki waho o te porowhita ki te triethylene glycol flash tank.Ko te glycol taonga ka whakahekehia ki te 0.4mpa ~ 0.6mpa i roto i te tank flash, me te hydrocarbon. ko te hau me etahi atu haurehu kua rewa i roto i te triethylene glycol ka whiti ki waho, ka whakamahia tenei wahanga o te hau hei hau wahie mo te whakangihangia o te ahi.
Ka kuhu te triethylene glycol wai whai kiko ki roto ki te tātari miihini ki te tarai i nga poke miihini, katahi ka uru ki te tātari waro whakahohe hei whakauru atu i nga matū waiwaro kua memeha i roto i te triethylene glycol me nga matū whakaheke o te triethylene glycol. Katahi ka uru ki roto ki te pereti-momo-momona-nui-a-waa whakawhiti wera wai, whakawhiti wera me te triethylene glycol hiroki teitei-te wera mai i te taika whakawhiti wera i te taha o raro o te triethylene glycol reboiler, ka wera ki te ~150 °C ki te uru. te pou whakatika wai whai rawa.
I roto i te reboiler triethylene glycol i te taha o raro o te pou whakatikatika, ka whakamahanahia te triethylene glycol ki te 193 ℃, a ko te wai i roto i te triethylene glycol ka wehea, ka tukuna mai i te tihi o te pou whakatika na roto i te paanga hautanga o te pou whakatika. Ko te glycol hiroki me te kukū tata ki te 99% (wt) ka puhake mai i te tīwae tihorea wē hiroki i roto i te kōhua ki te raro triethylene glycol pūkei whakawera whakawhiti wera. I raro i te mahi o te hau maroke i roto i te tīwae tihorea wai hiroki, te kukū glycol hiroki tomo i roto i te wera whakawhiti pūreirei tank taea tae 99.5% ~ 99.8%.
I roto i te tank buffer glycol, ka uru te glycol kikokore me te mahana o te 193 °C ki te whakawhiti wera glycol hiroki ki te whakawhiti i te wera me te glycol taonga, ka heke te pāmahana ki te 100 °C ka uru ki te papu. Ko te triethylene glycol wai hiroki ka pupuhi ki roto i te whakawhiti wera hau-wai i waho o te pourewa whakauru, a, i muri i te whakamatao me te kaitahuri wera hau i waho o te pourewa, ka uru ki te tihi o te pourewa whakauru mai i te waahanga o runga o te pouaka ki te whakaoti i te tohanga whakarewa.
Ko te hau maroke i tangohia mai i te wahanga putorino hau maroke i te putanga o te pourewa absorption ko te hau tihorea o te pou whakatika.
