Kaihanga Tipu LNG Haina Kounga teitei - He mahi hangahanga LNG iti kua eke ki runga i te tipu LNG - Rongteng

Ko te hau maaori liquefied (LNG) he hau maori, te nuinga o te mewaro, kua whakamatao ki te ahua wai kia noho humarie me te haumaru o te rokiroki me te kawe. Ka nui ake te 1/600th te nui o te hau maori i roto i te ahua hau.

Ka whakaratohia e matou nga Tipu Whakaheke Hau Maori i roto i te moroiti (mini) me te iti. Ko te kaha o nga tipu ka kapi mai i te 13 ki te neke atu i te 200 Tons/ra o te hanga LNG (18,000 ki te 300,000 Nm³/d).

Whangai hau:

• ● Nga papa hau kua paea
• ● hau hono / mura
• ● Biogas
• ● Paipa hau

E toru nga punaha o te tipu whakakaha LNG: te punaha tukanga, te punaha whakahaere taputapu me te punaha whaipainga. E ai ki nga momo puna hau, ka taea te whakarereke.

E ai ki te ahuatanga o te puna hau, ka tangohia e matou te mahinga pai me te kaupapa tino ohanga ki te whakatutuki i nga whakaritenga rereke a nga kaihoko. Ko nga taputapu kua eke ki runga ake ka ngawari ake te kawe me te whakaurunga.

1. Pūnaha tukanga me te tukanga hanga LNG

Ka pehia te hau maaori whangai i muri i te tātari, te wehenga, te whakaritenga pehanga me te ine, ka uru ki roto i te punaha whakamaoritanga hau maori. I muri i te tango CO₂, H₂S ,Hg, H₂O me te waiwaro taumaha, ka uru ki te pouaka makariri liquefaction. Na ka whakamataohia i roto i te pereti whakawhiti wera, ka whakakorehia i muri i te whakahekenga, ka whakahekehia i muri mai, ka werohia, ka kohia ki te tank flash, ka mutu, ka uru te wahanga wai wehe ki roto i te tank rokiroki LNG hei hua LNG.

Ko te tūtohi rerenga o te paheketanga kua ekeLNG Plante whai ake nei:

Ko te punaha tukanga o te cryogenicLNG Plantkei roto:

• ● Whāngai tātari hau, wehenga, ture pēhanga me te wae inenga;
• ● Whangai wae hau pressurization
• ● Ko te waeine o mua i te maimoatanga (tae atu ki te whakakore i te waikura, te whakamakuku me te tango waiwaro taumaha, te mercury me te tango puehu);
• ● Waeine whakataurite MR me te wae huringa MR kōpeketanga;
• ● Waeine liquefaction LNG (tae atu ki te waeine denitrification);

1.1 Nga ahuatanga o te punaha tukanga hanga LNG

1.1.1 Whangai wae hau i mua i te maimoatanga

Ko te tikanga tukanga o te waeine hau hau i mua i te maimoatanga ko nga ahuatanga e whai ake nei:

• ● Ko te whakamaaramatanga me te otinga MDEA he iti te hukahuka, he iti te pirau me te iti o te mate amine.
• ● Ka whakamahia te molecular sieve adsorption mo te whakamaroketanga hohonu, a he nui tonu te painga o te adsorption ahakoa i raro i te iti o te pehanga wahanga kohu wai.
• ● He iti te utu ki te whakamahi i te waro whakakorikori i te whanariki-impregnated hei tango i te mercury. Ka tauhohe a Mercury ki te whanariki i runga i te whanariki kua whakapourihia te waro whakakorikori ki te whakaputa i te mercury sulfide, ka uruhia ki runga i te waro whakahoaho hei whakatutuki i te kaupapa o te tango mercury.
• ● Ka taea e huānga tātari pū te tātari i te tatari rāpoi me te puehu waro whakahohe i raro 5μm.

1.1.2 Waehe wai me te pouaka whakamatao

Ko te tikanga tukanga kua tohua mo te liquefaction me te waeine whakamatao ko te MRC (te whakamatao whakauru) te whakamatao huringa, he iti te kohi hiko. Ko tenei tikanga he iti rawa te kohi hiko i waenga i nga tikanga whakamatao e whakamahia nuitia ana, ka whakataetae te utu o nga hua ki te maakete. He ahua motuhake te waeine whakawehenga whakamahana i te waeine kōpeketanga tohanga. I te wa e mahi ana, ka whakakiia e te waeine whakatairite te whakamahana ki te waeine compression circulating, kia mau tonu te ahua mahi o te wae compression circulating; I muri i te katinga o te waeine, ka taea e te waeine whakataurite te penapena i te pouaka whakamatao mai i te waahanga pehanga teitei o te waahanga whakakoi me te kore e tukuna te pouaka. Kaore e taea e tenei anake te whakaora i te whakamahana, engari ka whakapoto i te wa whakaoho e whai ake nei.

He paiherea nga marere katoa i roto i te pouaka makariri, karekau he hononga flange i roto i te pouaka matao hei whakaiti i nga tohu rerenga ka taea i roto i te pouaka makariri.

1.2 Nga taputapu matua o ia Waeine

2. Pūnaha whakahaere taputapu

Kia pai ai te aro turuki i te tukanga whakaputa o te huinga taputapu katoa, me te whakarite i te mahi pono me te mahi watea me te tiaki, kei roto i te punaha whakahaere taputapu:

Pūnaha mana tohatoha (DCS)

Pūnaha Taputapu haumaru (SIS)

Pūnaha Whakaoho Ahi me te Pūnaha Tiro Hau (FGS)

Pouaka whakaata-kati (CCTV)

Pūnaha tātari

Me nga taputapu tino tika (te rerenga rerenga, te kaitirotiro, te ine wera, te pehanga hiko) e tutuki ana i nga whakaritenga o te tukanga. Ko tenei punaha e whakarato ana i nga whirihoranga tino pai, te tono me nga mahi tirotiro, tae atu ki te tango raraunga tukanga, te whakahaere kati-kopiko, te mana whakahaere o te taputapu, te honohono whakaoho me te ratonga, te tukatuka raraunga me te whakaaturanga, te ratonga o te ahua, te whakaaturanga whakairoiro, te ratonga rekoata whakahaere me etahi atu mahi. Ina he ohorere i roto i te waahanga whakaputa, ka tukuna ranei e te punaha FGS he tohu whakaoho, ka tukuna e te SIS he tohu whakamarumaru whakamarumaru hei tiaki i nga taputapu kei runga i te waahi, ka whakamohio atu te punaha FGS ki te tari ahi ahi i te wa ano.

3. Pūnaha taputapu

Kei roto i tenei punaha: te wae rangi taputapu, te hauota, te hinu whakawhiti wera, te wai whakaheke me te wai whakamatao.
