Kupu Whakataki
Ko te hau maaori waipiro, e kiia nei ko te LNG, kei te whakamatao i te hau maaori ki te wai ma te whakamatao i te hau maaori hau i raro i te pehanga noa ki te – 162 ℃. Ka taea e te liquefaction hau taiao te whakaora i te waahi rokiroki me te waahi waka, a he painga o te uara calorific nui, he mahi nui, he pai ki te toenga o te ture kawenga taone, he pai ki te tiaki i te taiao, te whakaiti i te paru o te taone me etahi atu.
Ko te waipiro te uho o te hanga LNG me te tipu LNG kua eke ki runga. I tenei wa, ko te nuinga o nga tikanga whakangao hau maori ko te tikanga whakaheke riipene, te whakangao i te rerigerant me te whakangao me te whakawhanui.
Ka whakamahia e te tukanga rewa hau maori a Cascade nga momo koropuputanga o te pouaka whakamahana i raro i te pehanga noa ki te whakaheke i te pāmahana whakamatao i ia taahiraa ki te whakatutuki i te kaupapa o te rewharewha hau maori.
Ko te huringa whakamatao whakauru (MRC) he mahinga e neke atu i te rima nga momo momo whakamatao whakauru maha-waahanga, penei i te C1 ~ C5 Hydrocarbons me te N2, ka whakamahia hei wai mahi ki te whakamatao, ki te whakaeto me te whakawhänui i ia taahiraa ki te whiwhi i te kaha whakamahana i rerekē ngā taumata pāmahana, kātahi ka whakamatao, ka rewa te hau māori. Ka wehewehea te tukanga whakakorikori whakakao ki te maha o nga momo huringa whakamatao.
Ko te tukanga liquefaction ki expander e pā ana ki te tukanga o te hau māori liquefaction mā te whakamahi refrigerant pēhanga teitei ki te mohio whakamuri Claude huringa refrigeration ki te roha adiabatic o turbo expander.
Ko te kaupapa mahi te nuinga ko: whangai hau hau whakahaere me te ine i te waeine, te hau maaori mo te purenga me te hau maaori liquefaction wae, te punaha rokiroki whakamahana, te punaha whakaahuru hurihanga, te rokiroki LNG me te waahanga uta.
Tawhā hoahoa
Hei hoahoa i te LNG Plant Skid, me hiahia te tawhā e whai ake nei.
1) Nga tikanga taketake o te hoahoa tipu:
Whangai rere hau
Te pehanga hau whangai
Te pāmahana hau whangai
Ko te ihirangi wai kore utu o te hau whangai
2）Te hanga hau hau kai (mole%)
3) Nga whakaritenga hua:
hau māori liquefied:
Te pehanga putanga
Te pāmahana iti i raro i te pehanga putanga
Te ihirangi hauota teitei
Te nui o te waro hauhauora
