ʻO nā wai cryogenic e like me ka nitrogen wai (LN2), ka hydrogen wai (LH2), a me ke kinoea kūlohelohe wai (LNG) he mea nui i nā ʻoihana like ʻole, mai nā noi olakino a hiki i ka hana ikehu. ʻO ka lawe ʻana i kēia mau mea haʻahaʻa haʻahaʻa e pono ai nā ʻōnaehana kūikawā e mālama i ko lākou mau anuanu loa a pale i ka evaporation. ʻO kekahi o nā ʻenehana maikaʻi loa no ka lawe ʻana i nā wai cryogenic ʻo ia ka paipu hoʻoheheʻe ʻia. Ma lalo nei, e ʻimi mākou i ka hana ʻana o kēia mau ʻōnaehana a me ke kumu koʻikoʻi lākou no ka lawe palekana ʻana i nā wai cryogenic.

ʻO ka pilikia o ka lawe ʻana i nā wai Cryogenic

Mālama ʻia nā wai cryogenic a lawe ʻia ma nā mahana ma lalo o -150°C (-238°F). Ma ia mau haʻahaʻa haʻahaʻa, hoʻomaka lākou e evaporate wikiwiki inā ʻike ʻia i nā kūlana ambient. ʻO ka paʻakikī nui ka hoʻemi ʻana i ka hoʻoili wela e mālama i kēia mau mea i ko lākou kūlana wai i ka wā o ka lawe ʻana. Hiki i ka hoʻonui ʻana i ka wela ke hopena i ka vaporization wikiwiki, e alakaʻi ana i ka nalowale o ka huahana a me nā pōʻino palekana.

ʻO ka Pipeline Vacuum Insulated: ʻO ke kī i ka lawe ʻana maikaʻi

ʻO nā laina paipu i hoʻopaʻa ʻia i ka vacuum(VIPs) he hopena koʻikoʻi no ka lawe ʻana i nā wai cryogenic ma kahi lōʻihi me ka hōʻemi ʻana i ka hoʻoili wela. ʻO kēia mau paipu he ʻelua papa: kahi paipu i loko, kahi e lawe ai i ka wai cryogenic, a me kahi paipu waho e hoʻopili ai i ka paipu i loko. Aia ma waena o kēia mau papa ʻelua kahi ʻūhā, e lawelawe ana ma ke ʻano he pale insulating e hōʻemi i ka lawe ʻana i ka wela a me ka radiation. ʻO kapaipu hoʻoheheʻe ʻiaʻO ka ʻenehana e hoʻemi nui i nā poho wela, e hōʻoia i ka noho ʻana o ka wai i ka mahana i makemake ʻia i kāna huakaʻi.

Noi ma LNG Transportation

ʻO ke kinoea kūlohelohe wai (LNG) kahi kumu wahie kaulana a pono e lawe ʻia ma nā wela haʻahaʻa e like me -162°C (-260°F).ʻO nā laina paipu i hoʻopaʻa ʻia i ka vacuumhoʻohana nui ʻia i nā keʻena LNG a me nā pahu e hoʻoneʻe ai i ka LNG mai nā pahu mālama i nā moku a i ʻole nā ​​​​mea halihali ʻē aʻe. ʻO ka hoʻohana ʻana i nā VIP e hōʻoia i ka liʻiliʻi o ka wela, e hōʻemi ana i ka hoʻokumu ʻana o ka boil-off gas (BOG) a me ka mālama ʻana i ka LNG i kona kūlana liquefied i ka wā o ka hoʻouka ʻana a me ka wehe ʻana i nā hana.

ʻO ka wai wai wai a me ka wai nitrogen transport

Pēlā nō,nā paipu i hoʻopaʻa ʻia i ka ʻūhāHe mea koʻikoʻi i ka lawe ʻana i ka wai hydrogen (LH2) a me ka wai nitrogen (LN2). No ka laʻana, hoʻohana mau ʻia ka hydrogen wai i ka ʻimi ʻana i ka lewa a me ka ʻenehana wahie. Pono kona wahi paila haʻahaʻa loa o -253°C (-423°F) i nā ʻōnaehana kaʻaahi kūikawā. Hāʻawi nā VIP i kahi hopena kūpono, e ʻae ai i ka neʻe palekana a me ka maikaʻi o LH2 me ka pohō nui ʻole ma muli o ka hoʻoili wela. ʻO ka nitrogen wai, hoʻohana nui ʻia i nā lāʻau lapaʻau a me nā noiʻi ʻoihana, e pōmaikaʻi hoʻi mai nā VIP, e hōʻoiaʻiʻo ana i kona mahana paʻa i ke kaʻina hana.

Ka Hopena: Ke kuleana oNā Paipu Hoʻomāmā i ka wā e hiki mai ana o Cryogenics

Ke hoʻomau nei nā ʻoihana i nā wai cryogenic, nā paipu i hoʻopaʻa ʻia i ka ʻūhāe pāʻani ana i kahi kuleana nui i ka hōʻoia ʻana i kā lākou halihali palekana a maikaʻi. Me ko lākou hiki ke hōʻemi i ka hoʻoili wela, pale i ka nalowale o ka huahana, a hoʻonui i ka palekana, he mea koʻikoʻi nā VIP i ka ulu cryogenic māhele. Mai ka LNG a hiki i ka hydrogen wai, e hōʻoia kēia ʻenehana e hiki ke lawe ʻia nā wai haʻahaʻa haʻahaʻa me ka liʻiliʻi o ka hopena o ke kaiapuni a me ka maikaʻi loa.
