Whakaahuatanga
Ko te hau māori wai, e kiia pototia ana ko te LNG, he whakatōtō i te hau māori hei wai mā te whakamatao i te hau māori hau i raro i te pēhanga noa ki te – 162 ℃. Ka taea e te wai te penapena nui i te wāhi rokiroki me te wāhi kawe i te hau māori, ā, he pai hoki ngā painga o te nui o te uara wera, te mahi teitei, te āwhina i te taurite o te whakahaere kawenga tāone, te āwhina i te tiaki taiao, te whakaiti i te parahanga tāone me ētahi atu.
Ko te waikeri te kaupapa matua o te hanga LNG. I tēnei wā, ko ngā tukanga waikeri hau māori kua pakeke ko te tukanga waikeri cascade, te tukanga waikeri hauhautanga whakauru me te tukanga waikeri me te whakawhanui.
Ka whakamahia e te tukanga whakarewa hau māori Cascade ngā ira kohua rerekē o te hau mātao i raro i te pēhanga noa hei whakaiti i te pāmahana pouaka whakamātao taahiraa i te taahiraa kia tutuki ai te kaupapa o te whakarewa hau māori.
Ko te huringa hauhautanga whakauru (MRC) he tukanga e whakamahia ana neke atu i te rima ngā momo hauhautanga whakauru maha-wāhanga, pērā i ngā hauwaiwaro C1 ~ C5 me te N2, hei wai mahi hei whakapūmau, hei mimiti me te whakawhanui i ia taahiraa kia whiwhi ai i te kaha whakamatao i ngā taumata pāmahana rerekē, kātahi ka whakamatao haere, ka whakawaiwai i te hau maori. Kua wehea te tukanga whakawaiwai hauhautanga whakauru ki ngā momo huringa whakamatao maha.
Ko te tukanga whakawaiwai me te whakawhanui e pā ana ki te tukanga whakawaiwai hau māori mā te whakamahi i te hau whakamatao pēhanga teitei hei whakatutuki i te whakamatao huringa Claude whakamuri me te whakawhanui adiabatic o te turbo expander.
Ko te kaupapa tukanga matua ko: te waeine whakahaere me te ine i te pēhanga hau whāngai, te waeine purenga hau māori me te waeine waimeha hau māori, te pūnaha rokiroki hau whakamatao, te pūnaha kōpeketanga toiao o te hau whakamatao, te waeine rokiroki me te uta LNG.
Ko te hau māori e tomo ana ki te teihana ka haere tuatahi mā te wāhanga whakahaere me te ine pēhanga, e whakahaere ana i te whakahaere pēhanga me te ine i te hau māori e tomo mai ana; ka tomo te hau māori ki te wāhanga purenga hau māori, ka tangohia te CO2, ka tangohia te H2S me te maimoatanga maroke. E taunakihia ana te tukanga MDEA mō te tango waro me te tango H2S, e taunakihia ana te tukanga maroke tātari ngota me te tukanga maroke TEG toru-pou RĀNEI mō te maroke; ā, e taunakihia ana kia whakamahia te BOG kua whakahokia mai, kua pēhia hoki mō te hau whakaora.
Ka tāpirihia te hau māori parakore ki roto i te wāhanga whakapūnga hau māori, ka tūtohutia te hauhautanga whakauru (tukanga whakapūnga MRC) mō te whakapūnga hau māori; ka rongoatia te LNG waikura ki roto i te tāke rokiroki, ā, ka tūtohutia te tukanga rokiroki hauhautanga me te pāmahana iti mō te rokiroki LNG. Kotahi te tāke rokiroki hauhautanga pāmahana iti kua rite ki te pūnga BG, ā, ka whakamahia te pūnga BOG hei pēhi i te BOG i mua i te whakaurunga ki te whakamaroke tātari ngota. Te Whakahoutanga, i runga i te papu cryogenic hei whakatutuki i te tāutanga.
