1 Tirohanga Pūnaha

Ka uru te hau kai ki roto i te punaha whakahaere hau maori i muri i te tātari, te wehe, te pehanga me te mita. I muri i te tango CO₂, H₂ O, waiwaro taumaha me te Hg, ka uru ki roto i te pouaka matao liquefaction, ka whakamataohia, ka rewa, ka whakamatao, ka werohia i roto i te whakawhiti wera pereti. Katahi ka uru ki roto i te tank rokiroki LNG hei hua LNG.

Ko nga tikanga hangarau matua o tenei taputapu ko:

• Whakamahia te MDEA ki te tango i te hauhā;

• Ka whakamahia nga tatari rapoi hei tango i te wair
• Whakamahia te waro whakahohe hei tango i nga hauwai taumaha;

• Whakamahia te waro whakakorikori whanariki-impregnated hei tango i te mercury;

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

• Ko nga hau maaori katoa kua purea ka whakawirihia e te MRC (te whakamatao whakauru) te tukanga whakamatao huri noa;

  Kei roto i tenei punaha tukanga:

• Whangaia te tātari hau me te wehenga, te whakaritenga pehanga me te punaha ine;

• Pūnaha maimoatanga o mua (tae atu ki te whakakore warowaiha, te whakamaroketanga, te tango waiwaro taumaha, te tango mercury, me te tango puehu);

• Pūnaha whakaōrite MR me te pūnaha huringa kōpeketanga MR;

• Pūnaha liquefaction LNG;

• Pūnaha hangarua BOG

2  Whakaahuatanga o ia punaha

2.1     Whangaihia te wehenga tātari hau me te waeine whakahaere pehanga

1) Whakaahuatanga tukanga

Ko te hau whangai mai i te awa whakarunga ka whakatauhia te pehanga katahi ka uru ki roto ki te whakawehe tātari urupa hau kai, katahi ka uru ki te punaha whakararo i muri i te kopeke, te wehe me te mita.

Ko tana taputapu tukanga matua ko te kai whakawehe tātari hau, mita rere, compressor me etahi atu.

2) Tawhā hoahoa

Te kaha whakahaere: 10×10⁴Nm³/ra

Awhe Whakatikatika: 50%~110%

Te pēhanga putanga kōpeke: 5. 2Mpa.g

2.2     Whangai wae hau deacidification

1) Whakaahuatanga tukanga

Ko te hau whangai mai i te awa whakarunga ka uru ki roto i te waeine deacidification, a ka whakamahia e tenei waahanga te tikanga o te otinga MDEA hei tango i nga hau waikawa penei i te CO₂me H₂S i roto i te hau whangai.

Ko te hau maori ka kuhu mai i te taha o raro o te pourewa absorption ka haere i roto i te pourewa absorption mai i raro ki runga; ko te otinga MDEA kua whakahoutia (te wai hiroki) ka uru mai i te pito o runga o te pourewa whakauru, ka haere i roto i te pourewa absorption mai i runga ki raro, a ko te otinga MDEA me te hau maori e rere ana i te huarahi rereke kei roto i te pourewa absorption Ka tino whakapiri atu, te CO₂i roto i te hau_ko ka kuhu ki roto i te wahanga wai, ka kumea mai nga waahanga kaore i uru mai i te tihi o te pourewa whakauru ka uru ki te whakamatao hau me te whakawehe. Ko te hau e puta ana i te whakawehe hau decarburization ka uru ki roto i te waahanga tango hau mēkuri whāngai, ka haere te condensate ki te tank flash.

CO₂He iti iho i te 50ppmv nga ihirangi o te taiao kua rongoa.

MEDA absorbed CO₂ ka kiia ko te wai whai rawa, ka tukuna ki te pourewa uira, a ko te hau maaori i whiti i raro i te whakaheke pehanga ka tukuna ki te punaha wahie. Whai muri i te kanapa, ka huri te wera o te wai nui ki te otinga (wai hiroki) ka rere mai i raro o te pourewa whakaora, katahi ka piki ake te pāmahana ki te ~98°C ki te haere ki te pito o runga o te pourewa whakaora.

Ko te wai hiroki mai i te pourewa whakaora ka haere i roto i te whakawhiti wera wai hiroki me te whakamatao wai hiroki, ka whakamataohia te wai hiroki ki te ~40 ℃, a, ka pehia e te papu wai hiroki, ka uru mai i te pito o runga o te pourewa absorption.

Ko te hau kei te putanga o runga o te pourewa whakaora ka haere i roto i te whakamatao hau waikawa ka uru ki te whakawehe hau waikawa. Ka tukuna te hau mai i te wehenga hau waikawa ki te punaha whakaheke hau waikawa, ka pehia te condensate e te papu whakaora, ka tukuna ki te whakawehe flash.

Ko te puna wera o te reboiler pourewa whakahou ka whakamahanahia e te hinu whakawhiti wera.

Ko te taputapu tukanga matua o tenei waahanga ko te pourewa absorption me te pourewa whakaora.
