Pūnaehana hoʻopaʻa wai lua no ka pahu mālama cryogenic

Nā pahu mālama wai cryogenichoʻohana nui ʻia i ka ʻoihana kemika. No ka mea, he mau kemika weliweli ka waihona waihona, i mea e mālama pono ai i ka hoʻohana pono ʻana i nā pahu mālama haʻahaʻa wela. Pono e hoʻopaʻa ʻia kahi sila nitrogen ma waena o nā papa o loko a me waho o ka pahu mālama haʻahaʻa haʻahaʻa no ka mālama ʻana i ke kaomi maikaʻi o ka papa waena e pale ai i ka ea haʻahaʻa mai ke komo ʻana a hōʻoia i ka hana insulation thermal maikaʻi o nā huahana kemika.

Eia hou,nā pahu mālama wela haʻahaʻapono e hoʻolako i nā mea palekana palekana e pili ana. Pono ka pahu o ka pahu mālama cryogenic me kahi ʻōnaehana interlock alarm level. Ke ʻoi aku ka kiʻekiʻe o ka pae wai o ka pahu mālama haʻahaʻa haʻahaʻa ma mua o ka waiwai i hoʻonohonoho ʻia, ua hoʻāla ʻia ka ʻūhā wai kiʻekiʻe, a i ka wā i hiki ai ke kiʻekiʻe o ka wai kiʻekiʻe, ua hoʻāla ʻia ka ʻōnaehana interlock e pani i ka valve ma ka paipu inlet pahu wai wela haʻahaʻa.

Ke emi ka pae wai i loko o ka pahu cryogenic ma mua o ka waiwai i hoʻonohonoho ʻia, e hoʻāla ʻia kahi haʻahaʻa haʻahaʻa wai. Ke hiki i ka pae haʻahaʻa, hoʻāla ʻia ka ʻōnaehana interlock, pani ʻia ka valve ma ka paipu hoʻoheheʻe wai o ka pahu mālama cryogenic, a ua pani ʻia ka pauma hoʻouka. Eia kekahi, e loaʻa i ʻelua pūʻulu o ka nānā ʻana i ke kaomi a me nā ʻōnaehana interlocking alarm. Ke kiʻekiʻe ke kaomi o ka pahu waihona haʻahaʻa haʻahaʻa ma mua o ka waiwai i hoʻonohonoho ʻia, e hoʻāla ʻia kahi ʻōhua kiʻekiʻe, e hoʻāla ʻia ka ʻōnaehana interlocking, a e pani ʻia ka valve aunoa ma ka pipeline o ka ʻōnaehana booster e hoʻōki i ka hoʻonui.Ke emi ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa pahu pahu ma mua o ka waiwai i hoʻonohonoho ʻia, e 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 e hoʻokumu ʻia ke kaomi i loko o ka pahu mālama. Ke hiki i ka haʻahaʻa haʻahaʻa, ua hoʻāla ʻia ka ʻōnaehana interlocking, ua wehe ʻia ka valve aunoa ma ka pipeline o ka cryogenic liquid storage tank pressurization system, a ua kaomi ʻia ka pahu mālama cryogenic o ka ʻāpana vaporization i ka pahu mālama kūloko.

ʻAʻoleʻo ia wale nō, aia kahi'ōnaehana palekana piha i loko o ka pahu mālama kemika,ʻo ia hoʻi, kahi pahu pale pale pālua a me ka pahu hanu lua, a hoʻohanaʻia ka valveʻekolu no ka hoʻololi. Ke piʻi ka pahu i loko o 25kPa, e hoʻokuʻu ka valve palekana i ke kaomi; ke emi iho ka puʻe o loko o ka pahu waihona ma lalo o -0.5kPa, wehe ka pahu hanu a komo ka ea i loko o ka pahu waihona no ka pale ʻana i nā mea hana.
