Mea Kiʻekiʻe ʻO Kina Aila A me Gas Mixed Transportation Exporters - LNG Liquefaction plant - Rongteng

ʻO ke kinoea kūlohelohe wai (LNG) he kinoea kūlohelohe, ʻoi aku ka nui o ka methane, i hoʻoluʻu ʻia i ke ʻano wai no ka maʻalahi a me ka palekana o ka mālama ʻana a me ka lawe ʻana. Lawe ʻo ia ma kahi o 1/600th ka nui o ke kinoea maoli ma ke kūlana kinoea.

Hāʻawi mākou i nā mea kanu hoʻoheheʻe kūlohelohe kūlohelohe i ka micro (mini) a me ka liʻiliʻi. ʻO ka hiki o nā mea kanu ke uhi mai 15 a ʻoi aku ma mua o 200 Tons / lā o ka hana LNG (18,000 a 300,000 Nm.³/d).

Hanai kinoea:

● Nā kahua kinoea pae ʻia
● kinoea pili / puhi ʻia
● Biogas
● Paipu kinoea

Aia i loko o kahi mea kanu LNG liquefaction he ʻekolu ʻōnaehana: ʻōnaehana kaʻina hana, ʻōnaehana hoʻokele mea kani a me ka ʻōnaehana pono. Wahi a nā kumu ea like ʻole, hiki ke hoʻololi.

E like me ke kūlana maoli o ke kumu kinoea, lawe mākou i ke kaʻina hana maikaʻi loa a me ka hoʻolālā ʻoi loa e hoʻokō i nā koi like ʻole o nā mea kūʻai aku. ʻOi aku ka maʻalahi o ka lawe ʻana a me ka hoʻokomo ʻana i nā lako skid.

1 Pūnaehana kaʻina hana

Hoʻopili ʻia ke kinoea kūlohelohe ma hope o ka kānana ʻana, kaʻawale ʻana, ka hoʻoponopono kaomi a me ka ana ʻana, a laila komo i ka ʻōnaehana hoʻomaʻemaʻe kinoea maoli. Ma hope o ka wehe ʻana iā CO₂, H₂S ,Hg, H₂ʻO a me nā hydrocarbons kaumaha, komo ia i ka pahu anu liquefaction. A laila, ua hoʻoluʻu i loko o ka pā fin exchanger wela, denitrified ma hope o liquefaction, a me ka subcooled aʻe, throttled a uila i ka flash pahu, a me ka hope, ka hoʻokaʻawale wai māhele komo i ka LNG waihona pahu e like me LNG huahana.

ʻO ka papa kuhikuhi holoʻokoʻa o ka Skid mounted LNG Plant penei:

ʻO ka ʻōnaehana kaʻina o ka cryogenic LNG Plant e komo pū ana:

• ● Hānai kinoea kānana, hoʻokaʻawale, kaomi hooponopono a me ka ana ana;
• ● Hānai kinoea pressurization unit
• ● ʻĀpana hoʻomaʻamaʻa mua (me ka deacidification, dehydration a me ka wehe ʻana o ka hydrocarbon kaumaha, ka mercury a me ka wehe ʻana i ka lepo);
• ● MR proportioning unit and MR compression cycle cycle;
• ● LNG liquefaction unit (me ka denitrification unit);

1.1 Nā hiʻohiʻona o ka ʻōnaehana kaʻina

1.1.1 Hanai kinoea pretreatment unit

ʻO ke ʻano kaʻina hana o ka feed gas pretreatment unit loaʻa nā ʻano penei:

• ● Loaʻa ka Deacidification me ka solution MDEA i ka huʻa liʻiliʻi, haʻahaʻa corrosiveness a me ka pohō amine liʻiliʻi.
• ● Molecular sieve adsorption ua hoʻohana 'ia no ka hohonu dehydration, a me ka mea i kiʻekiʻe adsorption pono ma lalo o haʻahaʻa wai mahu hapa puʻe.
• ● ʻO ka hoʻohana ʻana i ka sulfur-impregnated carbon activated e wehe i ka mercury he haʻahaʻa ke kumu kūʻai. Hoʻopili ka Mercury me ka sulfur ma ka sulfur impregnated activated carbon e hana i ka mercury sulfide, i hoʻopili ʻia ma ke kalapona hoʻāla e hoʻokō i ke kumu o ka wehe ʻana i ka mercury.
• ● Hiki i nā mea kānana kūpono ke kānana i ka kānana molekika a me ka lepo kalapona i hoʻoikaika ʻia ma lalo o 5μm.

1.1.2 Liquefaction a me refrigeration unit

ʻO ke ʻano kaʻina hana i koho ʻia no ka liquefaction a me ka ʻāpana refrigeration ʻo MRC (mixed refrigerant) cycle refrigeration, ʻo ia ka haʻahaʻa o ka ikehu. ʻO kēia kaʻina hana ka haʻahaʻa haʻahaʻa haʻahaʻa loa ma waena o nā ʻano mea hoʻonaninani maʻamau, e hoʻokūkū ana i ke kumukūʻai huahana ma ka mākeke. He kūʻokoʻa kūʻokoʻa ka ʻāpana refrigerant proportioning i ka ʻāpana kōmike kaapuni. I ka wā o ka hana, hoʻopiha ka mea hoʻohālikelike i ka mea hoʻoheheʻe i ka ʻāpana kōmike e hoʻopuni ana, e mālama ana i ke kūlana hana paʻa o ka ʻāpana kōmike kahe; Ma hope o ka pani ʻia ʻana o ka ʻāpana, hiki i ka ʻāpana hoʻohālikelike ke mālama i ka refrigerant mai ka ʻāpana kiʻekiʻe o ka puʻupuʻu kaomi me ka ʻole o ka hoʻokuʻu ʻana i ka refrigerant. ʻAʻole hiki i kēia ke mālama wale i ka refrigerant, akā hoʻopōkole hoʻi i ka manawa hoʻomaka hou.

Hoʻopili ʻia nā kiwi a pau i loko o ka pahu anu, a ʻaʻohe pili flange i loko o ka pahu anu e hōʻemi i nā wahi leakage i loko o ka pahu anuanu.

1.2 Nā mea hana nui o kēlā me kēia Unit

2 Pūnaehana hoʻomalu mea kani

I mea e nānā pono ai i ke kaʻina hana o ka hoʻonohonoho piha o nā lako, a no ka hōʻoia ʻana i ka hana hilinaʻi a me ka hana maʻalahi a me ka mālama ʻana, ʻo ka ʻōnaehana hoʻokele mea kani ka mea nui:

Pūnaehana mana hoʻolaha (DCS)

ʻōnaehana mea hana palekana (SIS)

Pūnaehana ʻike maka ahi a me ke kinoea (FGS)

Televi kaapuni pani (CCTV)

Pūnaehana kālailai

A me nā mea hana kiʻekiʻe (flowmeter, analyzer, thermometer, pressure gauge) i kūpono i nā koi kaʻina. Hāʻawi kēia ʻōnaehana i nā hana hoʻonohonoho kūpono, komisina a me ka nānā ʻana, me ka loaʻa ʻana o ka ʻikepili kaʻina, ka hoʻopaʻa ʻana i ka loop control, ke kūlana o ka nānā ʻana i nā mea hana, ka hoʻopili ʻana a me ka lawelawe ʻana, ka hoʻoili ʻana a me ka hōʻike ʻana i ka manawa maoli, ka lawelawe ʻana, ka hōʻike kiʻi, ka lawelawe hōʻike moʻolelo hana a me nā hana ʻē aʻe. Ke loaʻa kahi pilikia ma ka ʻāpana hana a i ʻole ka ʻōnaehana FGS e hoʻouna i kahi hōʻailona hōʻailona, ​​​​hoʻouna ka SIS i kahi hōʻailona interlock pale e pale i nā mea hana ma ka pūnaewele, a hoʻolaha ka ʻōnaehana FGS i ke keʻena ahi kūloko i ka manawa like.

3 Pūnaehana pono

ʻO kēia ʻōnaehana ka mea nui: ʻāpana ea mea hana, ʻāpana nitrogen, ʻāpana ʻaila hoʻoili wela, ʻāpana wai desalted a me ka ʻāpana wai hoʻoluʻu.
