Ka whakauruhia e te Skid Whakareka Hau te Whakakorenga o te Sieve Ngoikore me te Whakamaroketanga TEG mō ngā Whare Hanga LNG o te Whakatipuranga e Whai Ake Nei
I te mea e anga whakamua ana te umanga hau māori wai (LNG) o te ao ki ngā whakaritenga parakore teitei ake i te tau 2026, ko te reti whakareka hau kua whanake hei pokapū maimoatanga-mua kua whakauruhia katoatia, e whakakotahi ana i te tango whanariki tātari Molecular matatau me te waeine whakamaroke hau TEG hei tuku i te hau whāngai tino maroke, kore-whanariki mō te waimehatanga o raro.
I ngā wā o mua, i whakahaerehia e ngā pūnaha amine-based te tango i te hau waikawa nui, engari ko te reti whakareka hau o ēnei rā kei roto i teTe whakakorenga whanariki o te tātari ngota paparanga—mā te whakamahi i ngā zeolite hangai me ngā rahi pūwero kua tino whakahaeretia—hei whakakanapa i te awa hau mā te mimiti i ngā mercaptan toenga, COS, me te whai i te H₂S ki raro i ngā taumata iti iho i te ppm. He mea nui tēnei tango-whā hohonu mō ngā whakawhiti wera cryogenic o te tipu LNG, i reira ka taea e ngā matū whanariki iti te hanga totoka me te poke i te –162 °C.
Kei te taha o tēnei moenga tātari ngota ko te waeine whakamaroke hau TEG, e whakamahi ana i te triethylene glycol hei mimiti i te kohu wai, ka tutuki ai ngā hekenga tomairangi o te 40–60 °C, ā, ka whakaheke i te ihirangi wai ki raro iho i te 0.1 lb/MMscf. Ina whakaritea raupapatia ki runga i te paheke reka hau kotahi, mā te raupapa whakakotahi o te whakakorenga whanariki tātari ngota me te whakamaroke TEG ka tutuki i te hau kua tukatukahia ngā whakaritenga o te paipa me te whakaurunga tipu LNG me te kore e hiahiatia he oko motuhake, he nui te wāhi.
E whakaatu ana ngā raraunga mara hou mai i tētahi tipu LNG nui o Āhia ki te Tonga-mā-rāwhiti, ko te whakakapi i ngā waeine takitahi ki tētahi reti whakareka hau kua whakauruhia i whakaiti i te tapuwae mā te 35%, ā, i whakaiti hoki i te whakapaunga pūngao whakaora mā te tata ki te 20%. Ka whai hua anō hoki ngā kaiwhakahaere mai i ngā taputapu tahi, ngā takirere whakawhiti aunoa, me tētahi porowhita hau whakaora noa e arotau ana i te pai o te wera.
"I te mea kua kaha ake ngā here tukunga i tēnei tau, ehara te paheke reka hau i te mea he taputapu whakapiri noa iho—koinei te ngākau o ngā mahi pono o te tipu LNG," te kī a tētahi miihini tukanga matua i tētahi kamupene EPC matua. "Ko te whakakorenga whanariki o te tātari ngota ka whakarato i te oro whakamutunga, ko te Wāhanga whakamaroke hau TEG "e whakamana ana i te mahi ātete-huka; ka mahi tahi rātou, ka hanga he raupapa maimoatanga pakari e whakanui ana i te wā mahi waimeha."
I te mea ka piki haere te kaha o te LNG o te ao mā te neke atu i te 60 miriona tāne ia tau i waenga i te tau 2026–2027, ka piki haere te hiahia mō ngā reti whakareka hau kiato, mahi teitei me te tātari ngota whakauru me te whakamaroke glycol, ka akiaki i te auahatanga i roto i te hoahoa modular e mau ana ki te reti me ngā āheinga aroturuki mamao.
