lng cryogenic waihona pahu hoʻohālike

ʻO ka LNG cryogenic storage tank i loaʻa ma ka hoʻomaʻemaʻe kinoea maoli, compressing a me ka wela ia, a me ka wehe 'ana i ka N2, CO2, H2O, sulfide, paʻa impurities, etc. ma lalo o ka hana o ka hui 'ana refrigerant, a me ka hope loaʻa LNG i loko o ka wai ano o -162 ° C. Ma hope o ka liquefaction kaʻina ma luna, ua hoemiia ka nui o ke kinoea maoli e 600. Mālama ʻia ka LNG i loko o kahi pahu mālama cryogenic ma -162 ° C a me ke kaomi ʻana ma kahi o 0.1 MPa.

(1) Hoʻokaʻawale oNā pahu mālama LNGma ka hiki
①Liʻiliʻi ka nui waihona pahu: ʻO ka hiki ke 5 ~ 50m³. Hoʻohana pinepine ʻia i nā wahi hoʻopiha kaʻa LNG kīwila a me nā keʻena liquefaction hau kīwila.
② Nā pahu hoʻopaʻa haʻahaʻa liʻiliʻi: 50 ~ 100m³, hoʻohana nui ʻia i nā hale hoʻoheheʻe kinoea ʻoihana.
③Large storage tank: ʻO ka mana he 100 ~ 1000m³, kūpono no nā hale hana LNG liʻiliʻi.
④Large waihona pahu: ka nui o 10,000 a 40,000 m³, hoʻohana ʻia no ke ʻano haʻahaʻa kumu a me ke ʻano hoʻoponopono kiʻekiʻe.
⑤ ʻO ka pahu hoʻopaʻa nui ʻē aʻe: ʻO 4 ~ 200,000 m³ ka nui, a hoʻohana ʻia ia no ke kahua hoʻokipa LNG.
I ka makahiki 1995, ua ʻoi aku ka nui o ka pahu waihona ma mua o 200,000 m³, a ua hoʻomohala ʻia i kahi pahu waihona nui.

(2) Hoʻokaʻawale ʻana i nā pahu mālama LNG ma ke ʻano
① Pahu pōʻai: Hoʻohana maʻamau no nā pahu hoʻopaʻa liʻiliʻi a liʻiliʻi (akā, hoʻohana pū kekahi mau pahu mālama nui i nā pahu spherical).
② Cylindrical tank: hoʻohana ʻia i nā pahu mālama o nā mana like ʻole.

(3) Hiki ke hoʻokaʻawale hou ʻia nā pahu mālama LNG cryogenic i ʻelua ʻano: ma luna o ka ʻāina a me ke ʻano o lalo (a. Semi-underground type; b. Full underground type; c. Underground pit type) e like me kahi i waiho ʻia ai.(4) Ka hoʻokaʻawale ʻana o nā pahu mālama LNG e like me kā lākou mea hana
①Bimetal ʻano: ʻO ka pahu i loko a me ka ʻili waho i hana ʻia me nā mea metala. Hana ʻia ka pahu o loko me ke kila kila kila a i ʻole alumini alumini, a ʻo ka pahu o waho i hana ʻia me ke kila nomoku kaomis.
② ʻAno kiʻiʻoniʻoni: ʻO ka cylinder i loko o kēia ʻano pahu waihona i hana ʻia me ke kila 36Ni me ka mānoanoa o 0.8 ~ 1.2mm.
③ ʻAno kaila i hoʻopaʻa ʻia: Ua kūkulu ʻia ka pahu o loko o kēia ʻano pahu waihona me nā mea metala pale cryogenic, a ua kūkulu ʻia ka pahu o waho me ka pāpaʻi prestressed.

(5) LNG cryogenic hale waihona ipu
①Vertical storage tank: hoʻohana ʻia kahi pahu mālama LNG kūʻokoʻa liʻiliʻi o 100m³ ma ke ʻano he mea hoʻokele kinoea no nā kaʻa.
②Ka pahu hoʻopaʻa keiki kāne-makuahine kū pololei: ʻO ka mea maʻamau, ʻekolu a ʻoi aku paha nā pahu kaikamahine i hoʻohui like ʻia e hana i kahi pahu i loko e hoʻokō ai i nā koi no ka mālama ʻana i ka waihona wai nui. ʻO kona ʻano, ʻo ia ka hui ʻana o nā pahu keiki he nui (maʻa mau 3 a 7) ma kahi ʻaoʻao i loko o kahi pahu nui waho (i kapa ʻia ʻo ka pahu makuahine). ʻO nā sub-tanks ka mea maʻamau i ka cylindrical vertical, a ʻoi aku ka nui o kēlā me kēia sub-tank ma mua o 100 ~ 150m³. He ʻano cylindrical ka pahu o waho me ka uhi ʻana i lalo o ka ʻaoʻao o lalo, a ʻo ka hapa nui o lākou he mau pahu mālama nui me ka nui o 300 ~ 1000m³ a me ke kaomi hana o 0.2 ~ 1.2MPa.
③ Poʻe pahu pahu pahu: ʻo nā pahu i loko a me waho he spherical. ʻO ka hapa nui he 200 ~ 1500m³, a ʻo ke kaomi hana he 0.2 ~ 1.0MPa.
④ ʻO nā pahu hoʻopaʻa maʻamau me nā pā i hoʻopaʻa ʻia: ʻO nā pahu mālama ma luna o ka ʻāina me ka mana o 80,000 m³, hoʻohana nui ʻia no nā pahu loaʻa LNG (ka mana kiʻekiʻe o 200,000 mm³)
