Pūnaehana hoʻopaʻa paʻa wai hoʻonohonoho lua no ka pahu mālama cryogenic

Nā pahu wai cryogenichoʻohana nui ʻia i ka ʻoihana ʻoihana. I mea e hōʻoiaʻiʻo ai i ka hoʻohana pono ʻana i nā pahu mālama cryogenic, pono e hoʻonohonoho ʻia nā sila nitrogen ma waena o nā ʻāpana pahu i loko a me waho o nā pahu mālama cryogenic no ka mālama ʻana i kahi kūlana paʻi maikaʻi o nā sandwich e pale i ke komo ʻana o ka ea haʻahaʻa. Ma waho aʻe o nā waiwai insulation wela maikaʻi o nā huahana kemika, he aha nā mea palekana palekana e pono ai e hoʻolako i nā pahu mālama haʻahaʻa haʻahaʻa.

No ka laʻana, pono e hoʻolako ʻia ka pahu i loko o ka pahu mālama cryogenic me ʻelua pūʻulu o nā ʻōnaehana hoʻāla wai. Ke kiʻekiʻe ke kiʻekiʻe o ka wai wai cryogenic storage tank ma mua o ka waiwai i hoʻonohonoho ʻia, hoʻāla ʻia ka alarm kiʻekiʻe kiʻekiʻe, a i ka wā i hiki ai ka pae wai kiʻekiʻe, hoʻāla ʻia ka ʻōnaehana interlock. E ʻoki i ka pahu ma ka paipu komo o ka pahu mālama cryogenic.

Ke emi iho ka pae wai o ka pahu wai mālama cryogenic ma mua o ka waiwai i hoʻonohonoho ʻia, hoʻāla ʻia ke ala haʻahaʻa haʻahaʻa. I ka hiki ʻana o ka pae wai haʻahaʻa haʻahaʻa, hoʻāla ʻia ka ʻōnaehana interlock, pani ʻia ka valve ma ka pipeline wai hoʻopaʻa wai cryogenic, a pani ʻia ka pauma hoʻouka. E hoʻonohonoho ia i ʻelua pūʻulu o ka nānā ʻana i ke kaomi a me nā ʻōnaehana interlocking alarm. Ke ʻoi aku ka kiʻekiʻe o ka pahu pahu mālama cryogenic ma mua o ka waiwai i hoʻonohonoho ʻia, e hoʻāla ʻia ka mea hoʻāla kiʻekiʻe, e hoʻāla ʻia ka ʻōnaehana interlocking, a me ka valve aunoa ma ka pipeline o ka ʻōnaehana booster o ka.pahu waihona LNGe pani ʻia e hoʻōki i ka hoʻonui. Paʻi.Ke emi iho ka puʻe pahu pahu cryogenic ma mua o ka waiwai i hoʻonohonoho ʻia, hoʻāla ʻia kahi puʻupuʻu haʻahaʻa haʻahaʻa, a wehe ʻia ka backflow regulating valve ma ka puka o ka BOG compressor i mea e hōʻoia ai ʻaʻole i hana ke kaomi pahu i loko o ka pahu mālama cryogenic. Ke hiki i ka haʻahaʻa haʻahaʻa, hoʻomaka ka ʻōnaehana interlock Wehe i ka valve aunoa ma ka pipeline o ka cryogenic storage tank pressurization system, a ʻo ka ʻāpana vaporized o ka cryogenic storage tank pressurizes ka pahu i loko.

ʻAʻole wale ia, aia kahi ʻōnaehana palekana piha i loko o ka pahu mālama cryogenic, ʻo ia hoʻi, nā ʻāpana ʻelua o nā pahu palekana a me nā ʻāpana ʻelua o nā pahu hanu, i hoʻololi ʻia ma o ka hoʻohana ʻana i nā kīwaha ala ʻekolu. Ke piʻi ka pahu o loko ma mua o 25kPa, hoʻomaka ka pahu palekana e hoʻokuʻu i ke kaomi; Ke emi iho ka pahu o loko ma lalo o -0.5kPa, wehe ka pahu hanu a komo ka ea i loko o ka pahu i loko e hōʻoia i ka pale ʻana i nā mea hana a me nā pilikia.
