ʻO nā mea kanu LNG kiʻekiʻe kiʻekiʻe Kina - 10 ~ 20 × 104m3 / D maʻamau LNG Liquefaction Plant - Rongteng

Ke ano o ka LNG

a) Hoʻohui

ʻO ka LNG / LCBM kahi hui hydrocarbon me ka methane ma ke ʻano he mea nui, aia kahi liʻiliʻi o ka ethane, propane, nitrogen a me nā mea ʻē aʻe i loaʻa i ke kinoea maoli.

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka methane o LNG / LCBM ma mua o 80% a ʻoi aku ka haʻahaʻa o ka nitrogen ma mua o 3%.

ʻOiai ʻo ka mea nui o ka LNG he methane, ʻaʻole hiki ke ʻike ʻia nā waiwai kino a me nā kemika o LNG mai ka methane maʻemaʻe.

Hiki ke loaʻa nā waiwai kino a me ka thermodynamic o ka methane a me nā ʻāpana kinoea ʻē aʻe ma nā puke kuhikuhi pili a me nā manual helu thermodynamic.

b) ʻAiʻa

ʻO ka nui o ka LNG / LCBM e pili ana i kāna mau ʻāpana, maʻamau ma waena o 430kg / m3 a me 470kg / m3, akā i kekahi mau mea hiki ke kiʻekiʻe e like me 520kg / m3. ʻO ka Density kekahi hana o ka mahana wai, a ʻo kona ʻano gradient ma kahi o 1.35kg/m3. ℃.

Nā lako o ka mea kanu LNG

1) ʻO ka ʻōnaehana kaʻina hana nui ka hoʻokumu ʻana o ka ʻōnaehana LNG / LCBM:

Hanai kinoea kānana a me ka ʻōnaehana hoʻoemi

Pūnaehana deacidification hanai kinoea

ʻōnaehana hoʻomaloʻo kinoea hānai

E hānai i ka ʻōnaehana hoʻohemo hydrocarbon kaumaha

ʻO ka wehe ʻana i ka mercury a me ka ʻōnaehana kānana o ke kinoea hānai

Hoʻomaʻemaʻe kinoea haʻahaʻa wela liquefaction system

ʻO ka mālama ʻana a me ka lawe ʻana a me ka ʻōnaehana bog compression

Pūnaehana pahu hau nui a me / a i ʻole ʻōnaehana hoʻoheheʻe kōkua

Pūnaehana kōkua palekana

Mea hana a me ka ʻōnaehana uila

2) Pūnaehana ʻōnaehana kōkua o ka ʻōnaehana kōkua mea kanu LNG / LCBM:

Pūnaehana wai hooluolu kaapuni

Pūnaehana mahu a / a i ʻole wai wela

Pūnaehana ea mea kani

Pūnaehana Nitrogen

Pūnaehana kinoea a i ʻole / a me ka ʻōnaehana aila
