Kaʻina hana hana LNG i kau ʻia ma 5 Mmscfd no ka hale hana LNG

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

Hāʻawi mākou i nā Hale Hana Liquefaction Kinoea Kūlohelohe ma ka liʻiliʻi a me ka liʻiliʻi. Uhi ka mana o nā hale hana mai 13 a ʻoi aku ma mua o 200 Tons/lā o ka hana LNG (18,000 a 300,000 Nm³/d).

Kinoea hānai:

• ● Nā kahua kinoea i hoʻopaʻa ʻia
• ● Kinoea pili / lapalapa
• ● Biogas
• ● Kinoea paipu

ʻO kahi hale hana hoʻoheheʻe LNG piha e komo pū ana me ʻekolu mau ʻōnaehana: ʻōnaehana hana, ʻōnaehana hoʻokele mea hana a me ka ʻōnaehana pono. Wahi a nā kumu ea like ʻole, hiki ke hoʻololi ʻia.

Wahi a ke kūlana maoli o ke kumu kinoea, mākoue hoʻohana i ke kaʻina hana maikaʻi loa a me ka hoʻolālā hoʻokele waiwai loa e hoʻokō ai i nā koi like ʻole o nā mea kūʻai aku.ʻOi aku ka maʻalahi o ka lawe ʻana a me ke kau ʻana me nā lako i kau ʻia ma luna o ka skid.

1. ʻŌnaehana hana a me ke kaʻina hana hana LNG

Hoʻokomo ʻia ke kinoea kūlohelohe hānai ma hope o ka kānana ʻana, ka hoʻokaʻawale ʻana, ka hoʻoponopono ʻana i ke kaomi a me ke ana ʻana, a laila komo i loko o ka ʻōnaehana hoʻomaʻamaʻa mua o ke kinoea kūlohelohe. Ma hope o ka wehe ʻana i ke CO₂, H₂S, Hg, H₂ʻO a me nā hydrocarbons kaumaha, komo ia i loko o ka pahu anu liquefaction. A laila hoʻomaʻalili ʻia i loko o ka mea hoʻololi wela plate fin, denitrified ma hope o ka liquefaction, a laila subcooling, throttled a flashed i ka pahu flash, a ʻo ka mea hope loa, komo ka pae wai i hoʻokaʻawale ʻia i loko o ka pahu mālama LNG ma ke ʻano he huahana LNG.

ʻO ke kaʻina hana o ka hale hana LNG i kau ʻia ma luna o ka skid penei:

ʻO ka ʻōnaehana hana o ka hale hana LNG cryogenic e komo pū ana me:

• ● Kānana kinoea hānai, hoʻokaʻawale, hoʻoponopono kaomi a me ka ʻāpana ana;
• ● ʻĀpana kaomi kinoea hānai
• ● Keʻena hoʻomaʻamaʻa mua (me ka deacidification, dehydration a me ka wehe ʻana i nā hydrocarbons kaumaha, ka wehe ʻana i ka mercury a me ka lepo);
• ● ʻĀpana hoʻohālikelike MR a me ka ʻāpana pōʻaiapuni hoʻopili MR;
• ● ʻĀpana hoʻoheheʻe LNG (me ka ʻāpana denitrification);

1.1 Nā hiʻohiʻona o ka ʻōnaehana hana hana LNG

1.1.1 ʻĀpana hoʻomākaukau mua o ke kinoea hānai

ʻO ke ʻano hana o ka ʻāpana hoʻomaʻamaʻa kinoea hānai nā ʻano penei:

• ● Loaʻa i ka deacidification me ka hopena MDEA nā pono o ka huʻa liʻiliʻi, ka corrosiveness haʻahaʻa a me ka pohō amine liʻiliʻi.
• ● Hoʻohana ʻia ka adsorption sieve molekala no ka maloʻo hohonu, a he kiʻekiʻe nō hoʻi kona pono adsorption ʻoiai ma lalo o ke kaomi hapa haʻahaʻa o ka mahu wai.
• ● ʻO ke kumu kūʻai haʻahaʻa ka hoʻohana ʻana i ke kalapona i hoʻoulu ʻia me ka sulfur e wehe i ka mercury. Hoʻopili ʻo Mercury me ka sulfur ma luna o ke kalapona i hoʻoulu ʻia me ka sulfur e hana i ka mercury sulfide, kahi i hoʻopili ʻia ma luna o ke kalapona i hoʻoulu ʻia e hoʻokō ai i ke kumu o ka wehe ʻana i ka mercury.
• ● Hiki i nā ʻāpana kānana kikoʻī ke kānana i ka sieve molekala a me ka lepo kalapona i hoʻāla ʻia ma lalo o 5μm.

1.1.2 ʻĀpana hoʻoheheʻe a me ka hoʻomaʻalili

ʻO ke ʻano hana i koho ʻia no ka liquefaction a me ka refrigeration unit ʻo ia ka MRC (mixed refrigerant) cycle refrigeration, ʻo ia hoʻi ka hoʻohana ʻana i ka ikehu haʻahaʻa loa. ʻO kēia ʻano hana ka mea hoʻohana ikehu haʻahaʻa loa ma waena o nā ʻano refrigeration i hoʻohana pinepine ʻia, e hoʻokūkū ana i ke kumukūʻai huahana ma ka mākeke. He kūʻokoʻa iki ka ʻāpana refrigerant proportioning mai ka ʻāpana compression circulating. I ka wā o ka hana, hoʻopiha hou ka ʻāpana proportioning i ka refrigerant i ka ʻāpana compression circulating, e mālama ana i ke kūlana hana paʻa o ka ʻāpana compression circulating; Ma hope o ka pani ʻia ʻana o ka ʻāpana, hiki i ka ʻāpana proportioning ke mālama i ka refrigerant mai ka ʻāpana kiʻekiʻe o ka ʻāpana compression me ka ʻole o ka hoʻokuʻu ʻana i ka refrigerant. ʻAʻole hiki i kēia ke mālama wale i ka refrigerant, akā e hoʻopōkole pū i ka manawa hoʻomaka aʻe.

Hoʻopili ʻia nā kiwikā āpau i loko o ka pahu anu, a ʻaʻohe pilina flange i loko o ka pahu anu e hōʻemi i nā wahi leakage hiki ke hiki i loko o ka pahu anu.

1.2 Nā lako nui o kēlā me kēia ʻĀpana

2. ʻŌnaehana hoʻokele mea hana

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 kūpono a me ka mālama ʻana, ʻo ka ʻōnaehana hoʻomalu mea hana nui nā mea:

ʻŌnaehana hoʻokele i hoʻolaha ʻia (DCS)

ʻōnaehana mea hana palekana (SIS)

ʻŌnaehana Hoʻāla Ahi a me ka ʻIke Kinoea (FGS)

Ke kīwī kaapuni pani (CCTV)

ʻŌnaehana loiloi

A me nā mea hana pololei kiʻekiʻe (ka mika kahe, ka mea kālailai, ka ana wela, ke ana kaomi) e hoʻokō ana i nā koi o ke kaʻina hana. Hāʻawi kēia ʻōnaehana i nā hana hoʻonohonoho kūpono, ke kauoha ʻana a me ka nānā ʻana, me ka loaʻa ʻana o ka ʻikepili kaʻina hana, ka mana pani ʻia, ke kūlana nānā ʻana i ka hana o nā lako, ka laka ʻana a me ka lawelawe ʻana i ka alarm, ka hana ʻana a me ka hōʻike ʻana i ka ʻikepili manawa maoli, ka lawelawe ʻano, 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 alarm, hoʻouna ka SIS i kahi hōʻailona pale interlock e pale i nā lako ma ka pūnaewele, a hoʻomaopopo ka ʻōnaehana FGS i ka ʻoihana kinai ahi kūloko i ka manawa like.

3. ʻŌnaehana pono hana

ʻO kēia ʻōnaehana ka mea nui: ka ʻāpana ea mea hana, ka ʻāpana naikokene, ka ʻāpana aila hoʻoili wela, ka ʻāpana wai desalted a me ka ʻāpana wai e hoʻolulu ana.
