Hana ʻia 50×10⁴m³/ D mea hoʻoheheʻe kinoea maoli

Hoʻolauna

ʻO ke kūkulu ʻana o ka papahana 50 × 10⁴m³ / D papahana hoʻoheheʻe kinoea maoli a me nā mea kākoʻo a me hoʻokahi pahu pahu piha piha 10000 m3 LNG. ʻO nā ʻāpana kaʻina hana nui e pili ana i ka hoʻoulu ʻana i ke kinoea feed, ka decarbonization unit, dehydration unit, mercury a me ke kaumaha hydrocarbon removal unit, liquefaction unit, refrigerant storage, flash steam pressurization, LNG tank farm and loading facilities.

Pehea e hana ai ka lapaʻau pre-liquefaction o ke kinoea maoli?

Hele mai ka punawai o ka ai mea kanu ma ke ano kinoea ma ka paipu. Loaʻa i ke kinoea maoli i unuhi ʻia mai ka lepo mai nā haumia, ka wai a me nā wai e pili ana, no laila ma mua o ka hiki ʻana o ka liquefaction, pono ke kinoea e hele i kahi kaʻina hana e wehe ai i nā mea makemake ʻole. Hele ke kinoea i loko o nā moku, compressors a me nā paipu kahi e hoʻokaʻawale ʻia ai ke kinoea mai nā wai kaumaha a me nā haumia.

ʻO ka mua, hoʻoneʻe ʻia ka wai a me ka condensate, ma hope oka wehe ʻana i ke kinoea ʻakika (carbon dioxide, CO2), hydrogen sulfide (H2S) a me ka mercury (Hg). ʻAʻole makemake ʻia kēia mau mea, no ka mea hiki ke hana i ka hau i ka wā liquefaction a me ka corrosion i nā pipeline a me nā mea hoʻololi wela LNG. Hoʻomaʻamaʻa mua ʻia ke koena hui ʻana, a laila hoʻokaʻawale ʻia nā wai kinoea ʻoi aku ke kaumaha mai ka hui ʻana ma mua o ka hana ʻana. Hiki ke mālama ʻia a kūʻai paʻa ʻia nā hydrocarbons i wehe ʻia. ʻO ke kinoea i koe ka hapa nui o ka methane a me kekahi ethane, i lawe ʻia i ka liquefaction.

ʻO ke kinoea kūlohelohe wai, i kapa ʻia ʻo LNG, e hoʻopololei ana i ke kinoea maoli i loko o ka wai ma o ka hoʻoluʻu ʻana i ke kinoea kūlohelohe ma lalo o ke kaomi maʻamau i - 162 ℃. Hiki i ka liquefaction kinoea maoli ke mālama nui i ka waiho ʻana a me ka wahi kaʻa, a loaʻa iā ia nā pōmaikaʻi o ka waiwai calorific nui, hana kiʻekiʻe, kūpono i ke koena o ka hoʻoponopono ukana kūlanakauhale, kūpono i ka mālama ʻana i ke kaiapuni, e hōʻemi ana i ka pollution kūlanakauhale a pēlā aku.

ʻO ka papahana kaʻina hana ka mea nui: ka hoʻoponopono ʻana i ke kaomi kinoea e hoʻoponopono a me ka ʻāpana mika,hui hoʻomaʻemaʻe kinoea maolia me ka hui hoʻoheheʻe kinoea maoli, ʻōnaehana hoʻopaʻa ʻana i ka mea hoʻoheheʻe, ʻōnaehana hoʻoheheʻe e hoʻoheheʻe ana i ka refrigerant, waihona LNG a me ka hoʻouka ʻana.

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 13 a ʻoi aku ma mua o 200 Tons / lā o ka hana LNG (18,000 a 300,000 Nm.³/d).

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, H₂ ʻO 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 (medeacidification,dehydrationa me ka wehe ʻana i 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:

• ●Deacidification me ka hoʻonā MDEALoaʻa ka pono o ka huʻa liʻiliʻi, haʻahaʻa corrosiveness a me ka liʻiliʻi amine poho.

• ●Molecular sieve adsorptionHoʻohana ʻia ia no ka dehydration hohonu, a loaʻa nō iā ia ka waiwai adsorption kiʻekiʻe ma lalo o ke kaomi ʻāpana wai haʻahaʻa.

• ● 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)

Pūnaehana 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 ʻike 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.
