Nga Kaituku Tipu LNG Kounga Nui o Haina - Te Rerehu Whakarerenga Hau Maori – Rongteng

Whakaahuatanga

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 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 liquefaction te matua o te hanga LNG. 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 refrigerant ranu (MRC) he tukanga e whakamahia ana neke atu i te rima nga momo momo whakamahana maha-waahanga, penei i te C1 ~ C5 Hydrocarbons me te N2, hei wai mahi ki te whakamatao, ki te whakaeto me te whakawhänui i ia taahiraa ki te whiwhi i te kaha o te pouaka whakamahana i nga taumata rereke rereke, katahi ka whakamataohia, ka rewa te hau maori. 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.

Ko te hau maori e uru ana ki te teihana ka haere tuatahi i roto i te waeine whakahaere pehanga me te inenga, e mohio ana ki te whakaritenga pehanga me te inenga o te hau maori taumai; Ko te hau o te taiao ka uru ki roto i te waahanga horoi o te hau taiao, kei reira te hau taiao e pa ana ki te tango CO2, te tango H2S me te maimoatanga matewai. Ko te tukanga MDEA e taunakihia ana mo te whakakorenga me te tango H2S, te tukanga whakamaroke molecular sieve me te toru nga pourewa OR TEG tukanga whakamaroketanga ka tūtohuhia mo te whakamaroketanga; A ka tūtohuhia kia whakamahia te BOG kua ora ake me te kopiri mo te hau whakaora;

Ko te hau maori kua purea ki roto i te waeine whakangao hau maori, ka tohua te whakamatao whakauru (te mahi MRC liquefaction) mo te rehu hau maori; Kei te rongoa te LNG liquefied ki roto i te tank rokiroki, ka tūtohuhia te tukanga rokiroki hau me te iti-mahana mo te rokiroki LNG. Ko tetahi tank rokiroki iti-mahana i runga i te rangi he taputapu BG compressor, ka whakamahia te BOG compressor ki te pehi i te BOG i mua i te urunga atu ki roto i te whakamaroke tatari molecular Regeneration, i runga i te papu cryogenic ki te whakatutuki i te whakaurunga.
