Ko te hau māori wai (LNG) he hau māori, ko te nuinga he methane, kua whakamataohia kia wai hei whakahaere i te rokiroki me te kawe. Tata ki te 1/600 o te rahinga o te hau māori i roto i te āhua hau.
Kei a mātou ngā Whare Whakarewa Hau Taiao i roto i ngā tauine iti me ngā tauine iti. Ko te kaha o ngā whare whakarewa ka kapi i te 13 ki te neke atu i te 200 Tāne ia rā o te hanga LNG (18,000 ki te 300,000 Nm).3/rā).
Hau whāngai:
-
● Ngā mara hau kua mau
-
● Hau e pā ana / hau mura
-
● Hau koiora
-
● Paipa hau
E toru ngā pūnaha o tētahi tipu whakapūngao LNG: te pūnaha tukatuka, te pūnaha whakahaere taputapu me te pūnaha whaipainga. E ai ki ngā pūtake hau rerekē, ka taea te whakarerekē.
E ai ki te āhua o te pūtake hau, ka whakamahia e mātou te tukanga pai rawa atu me te kaupapa tino ohanga hei whakatutuki i ngā hiahia rerekē o ngā kiritaki. Mā ngā taputapu e mau ana ki te paheke ka māmā ake te kawe me te tāuta.
1. Pūnaha tukatuka
Ka pēhangahia te hau māori whāngai i muri i te tātari, te wehenga, te whakahaere pēhanga me te ine, kātahi ka uru ki te pūnaha maimoatanga hau māori i mua. Whai muri i te tango i te CO2, H2S ,Hg, H2O me ngā warowaihā taumaha, ka uru ki te pouaka makariri waikeri. Kātahi ka whakamataohia i roto i te whakawhiti wera pereti, ka tangohia te waikawa i muri i te waikeri, kātahi ka whakamataohia, ka whakamātaohia, ka tukuna ki te tāke waikeri. Hei whakamutunga, ka uru te wāhanga wai kua wehea ki te tāke rokiroki LNG hei hua LNG.
Ko te tūtohi rere o te tipu LNG kua whakanohoia ki runga i te reti koia tēnei:
Ko te pūnaha tukanga o te Whare Hanga LNG cryogenic ko:
-
● Te tātari hau whāngai, te wehenga, te whakahaere pēhanga me te waeine ine;
-
● Wāhanga pēhanga hau whāngai
-
● Wāhanga maimoatanga mua (tae atu kite whakakore waikawa,matewaime te tango i te warowaihā taumaha, te tango i te konukōre me te puehu);
-
● Te waeine whakataurite MR me te waeine huringa kōpeketanga MR;
-
● Wāhanga whakapūkara LNG (tae atu ki te wāhanga whakapūkara);
1.1 Ngā āhuatanga o te pūnaha tukanga
1.1.1 Wāhanga maimoatanga hau whāngai
Ko ngā āhuatanga o te tikanga tukatuka o te waeine tukatuka hau whāngai:
-
●Te whakakore waikawa ki te otinga MDEAHe iti ngā painga o te pahuka, te iti o te waikura, me te iti o te ngaronga amine.
-
●Te mimiti i te tātari ngotae whakamahia ana mō te maroketanga hohonu, ā, he pai tonu te mimiti ahakoa i raro i te pēhanga ā-wāhanga iti o te kohu wai.
-
● He iti te utu mō te whakamahi i te waro whakahohe kua whakakiia ki te whanariki hei tango i te konutei. Ka tauhohe te konutei ki te whanariki ki runga i te waro whakahohe kua whakakiia ki te whanariki hei whakaputa i te konutei whanariki, ka mimitihia ki runga i te waro whakahohe hei whakatutuki i te kaupapa o te tango konutei.
-
● Ka taea e ngā huānga tātari tino tika te tātari i te tātari ngota me te puehu waro whakahohe i raro i te 5μm.
1.1.2 Wāhanga wai me te pouaka whakamātao
Ko te tikanga tukatuka kua tīpakohia mō te waeine wai me te pouaka whakamātao ko te MRC (whakamātao whakaranu) huringa pouaka whakamātao, he iti te whakapaunga pūngao. Ko tēnei tikanga te mea iti rawa te whakapaunga pūngao i roto i ngā tikanga pouaka whakamātao e whakamahia whānuitia ana, e whakataetae ana i te utu hua i te mākete. He motuhake te waeine whakataurite pouaka whakamātao i te waeine pēhitanga hurihuri. I te wā e mahi ana, ka whakakī anō te waeine whakataurite i te pouaka whakamātao ki te waeine pēhitanga hurihuri, kia mau tonu ai te āhua mahi pumau o te waeine pēhitanga hurihuri; I muri i te whakaweto i te waeine, ka taea e te waeine whakataurite te penapena i te pouaka whakamātao mai i te wāhanga pēhanga teitei o te waeine pēhitanga me te kore e tukuna te pouaka whakamātao. Ehara i te mea ka taea anake te penapena i te pouaka whakamātao, engari ka whakapoto hoki i te wā tīmatanga e whai ake nei.
He mea whakarewa ngā takirere katoa i roto i te pouaka makariri, ā, kāore he hononga flange i roto i te pouaka makariri hei whakaiti i ngā pūwāhi turuturu pea i roto i te pouaka makariri.

2. Pūnaha whakahaere taputapu
Hei aroturuki tika i te tukanga whakaputa o te huinga taputapu katoa, me te whakarite kia pono te mahi me te whakahaere me te tiaki watea, ko te pūnaha whakahaere taputapu te nuinga o ngā mea:
Pūnaha whakahaere tohatoha (DCS)
Pūnaha Taputapu Haumaru (SIS)
Pūnaha Whakaoho Ahi me te Pūnaha Kimi Hau (FGS)
Pouaka whakaata porowhita-kati (CCTV)
Pūnaha tātari
Me ngā taputapu tino tika (mita rere, tātari, inemahana, ine pēhanga) e tutuki ana i ngā whakaritenga o te tukanga. Ka whakaratohia e tēnei pūnaha ngā mahi whirihoranga, te whakatūnga me te aroturuki tino tika, tae atu ki te kohikohi raraunga tukanga, te whakahaere porowhita kati, te aroturuki i te mana whakahaere taputapu, te hononga me te ratonga whakaoho, te tukatuka me te whakaatu raraunga wā-tūturu, te ratonga au, te whakaatu whakairoiro, te ratonga pūrongo rekoata mahi me ētahi atu mahi. Ina puta he āhuatanga ohorere i roto i te wāhanga whakaputa, ina tukuna rānei e te pūnaha FGS he tohu whakaoho, ka tukuna e te SIS he tohu tiaki hononga hei tiaki i ngā taputapu kei te papaanga, ā, ka whakamōhio te pūnaha FGS ki te tari ahi ā-rohe i te wā kotahi.
3. Pūnaha whaipainga
Kei roto i tēnei pūnaha te nuinga o ngā mea: te waeine hau taputapu, te waeine hauota, te waeine hinu whakawhiti wera, te waeine wai tango tote me te waeine wai toiawhio whakamatao.
