1  Tirohanga Whānui o te Pūnaha

Ka uru te hau whāngai ki te pūnaha maimoatanga hau māori i muri i te tātari, te wehewehe, te whakahaere i te pēhanga me te ine. Whai muri i te tango i te CO₂, H₂Ko te O, ngā warowaihā taumaha me te Hg, ka uru ki te pouaka makariri wai, ā, ka whakamataohia, ka waikurahia, ka whakamataohia, ka whakamātaohia, ka whakawhāitihia i roto i te whakawhiti wera pereti-tara. Kātahi ka uru ki te tāke rokiroki LNG hei hua LNG.

Ko ngā tikanga hangarau matua o tēnei taputapu ko:

• Whakamahia te MDEA hei tango i te hauhā waro;

• Ka whakamahia ngā tātari ngota hei tango i te wair
• Whakamahia te waro whakahohe hei tango i ngā warowaihā taumaha;

• Whakamahia te waro whakahohe kua whakakiia ki te whanariki hei tango i te mercury;

• Whakamahia ngā huānga tātari tika hei tātari i te tatari ngota me te puehu waro whakahohe;

• Ka whakarewaina te hau maori parakore katoa mā te tukanga whakamatao hurihuri a te MRC (whakamahana hauhautanga whakaranu);

  Kei roto i tēnei pūnaha tukanga:

• Te tātari me te wehenga o te hau whāngai, te whakahaere pēhanga me te pūnaha ine;

• Pūnaha maimoatanga-mua (tae atu ki te tango waro, te whakamaroke, te tango hauwaiwai taumaha, te tango mercury, me te tango puehu);

• Pūnaha taurite MR me te pūnaha huringa kōpeketanga MR;

• Pūnaha whakapūmau LNG;

• Pūnaha hangarua BOG

2   Whakaahuatanga o ia pūnaha

2.1      Wāhanga wehenga tātari hau whāngai me te whakahaere pēhanga

1) Whakaahuatanga tukanga

Ka whakahaerehia te pēhanga o te hau whāngai mai i te taha whakarunga, kātahi ka tomo ki te wehewehe tātari hau whāngai, kātahi ka tomo ki te pūnaha whakararo i muri i te pēhanga, te wehenga me te ine.

Ko ngā taputapu tukatuka matua ko te wehewehe tātari hau whāngai, te mita rere, te compressor me ētahi atu.

2) Ngā tawhā hoahoa

Te kaha whakahaere: 10×10 ⁴ Nm ³ /rā

Awhe whakarerekētanga: 50%~110%

Pēhanga putanga o te kōpeke: 5.2Mpa.g

2.2      Wāhanga whakakore waikawa hau whāngai

1) Whakaahuatanga tukanga

Ka uru te hau whāngai mai i te awa whakarunga ki te wāhanga whakakore waikawa, ā, ka whakamahia e tēnei wāhanga te tikanga otinga MDEA hei tango i ngā hau waikawa pēnei i te CO2.₂ me H₂S i roto i te hau whāngai.

Ka tomo te hau māori mai i te pito o raro o te pourewa mimiti, ka haere mā roto i te pourewa mimiti mai i raro ki runga; ka tomo te otinga MDEA kua whakahoutia katoatia (wai kikokore) mai i te pito o runga o te pourewa mimiti, ka haere mā roto i te pourewa mimiti mai i runga ki raro, ā, ko te otinga MDEA me te hau māori e rere ana i te taha ke kei roto i te pourewa mimiti. Ina pa katoatia, ka puta te CO2.₂ i roto i te hau _ko ka mimitia ki te wāhanga wai, ā, ka tangohia ngā wāhanga kāore i mimitia mai i te tihi o te pourewa mimiti ka tomo ki te pouaka whakamatao hau me te wehewehe. Ko te hau e puta ana i te wehewehe hau whakakorenga ka tomo ki te wāhanga tango mercury hau whāngai, ā, ka haere te waipū ki te tāke mura.

CO₂ he iti iho i te 50ppmv te ihirangi o te waikawa matū kua tukatukahia.

CO kua mimitia e te MEDA₂ ka kiia he wai momona, ka tukuna ki te pourewa mura, ā, ko te hau māori i mura i raro i te whakaiti i te pēhanga ka tukuna ki te pūnaha wahie. I muri i te mura, ka whakawhiti te wai momona i te wera me te otinga (wai kikokore) e rere ana i waho o te pourewa whakaora, kātahi ka whakanuia te pāmahana ki te ~98 °C hei haere ki te wāhanga o runga o te pourewa whakaora.

Ka haere te wai kikokore mai i te pourewa whakaora mā te whakawhiti wera wai kikokore me te whakamatao wai kikokore, ka whakamataohia te wai kikokore ki te ~40 ℃, ā, i muri i te pēhanga e te papu wai kikokore, ka tomo mai i te taha o runga o te pourewa mimiti.

Ka haere te hau i te putanga o runga o te pourewa whakaora mā te pouaka whakamatao hau waikawa ka tomo ki te wehewehe hau waikawa. Ka tukuna te hau mai i te wehewehe hau waikawa ki te pūnaha tuku hau waikawa, ā, ka pēhia te wai whakapūhau e te papu whakaora, kātahi ka tukuna ki te wehewehe mura.

Ka whakamahanatia te pūtake wera o te kohua pourewa whakahou e te hinu whakawhiti wera.

Ko ngā taputapu tukatuka matua o tēnei waeine ko te pourewa mimiti me te pourewa whakaora.

2) Ngā tawhā hoahoa
