Ma ke ʻano he ikehu maʻemaʻe kiʻekiʻe, ʻoi aku ka maikaʻi, a maʻalahi hoʻi a me nā mea maka kemika, loaʻa i ke kinoea maoli ka mana hoʻohana nui. I waena o lākou, ua hoʻomaka ʻia ka liquefied natural gas (LNG), kahi kiʻekiʻe o ka mākeke, e huki i ka nānā ʻana i mea hoʻohui i nā kumu kinoea kuʻuna.
ʻOiai ʻo nā paipu LNG he mau paipu halihali waena haʻahaʻa maʻamau, ʻo ka LNG i lawe ʻia e nā paipu ma ke ʻano maʻamau he wai haʻahaʻa. Ke komo ka wela o waho, e maʻalahi ia e mahu, e hoʻololi ai ke kahe wai hoʻokahi-paepae i ke kahe ʻelua-paepae kinoea-wai, a i ʻole he laka kinoea, e hopena ana i ka piʻi ʻana o ke kaomi a me ka emi ʻana o ke kahe ʻana i nā ʻāpana paipu kūloko, e hoʻopilikia nui ana i ka halihali maʻamau o ka LNG. No laila, pono e kāohi pono ʻia ka mahu ʻana o ka LNG. Eia nō naʻe, hiki i ka insulation pipeline LNG ke pale i ke komo ʻana o ka wela o waho a me ka mahu ʻana o ka LNG, a ʻo kona pono e pili nui ana i ka maikaʻi o ka insulation o ka pipeline LNG. No laila, pono nā pipeline LNG e hoʻohana i nā ana insulation thermal , a ʻaʻole wale ko lākou maikaʻi e hoʻopilikia i ka pono o ka halihali ʻana o ka LNG, akā he hopena koʻikoʻi hoʻi i ka hana maʻamau o ka ʻōnaehana holoʻokoʻa.
Nā ʻano hoʻokaʻawale paipu LNG
ʻO ka hoʻoheheʻe ʻana: ʻO ke kumumanaʻo ka hana ʻana i ka ʻōnaehana insulation i loko o kahi interlayer i hoʻopaʻa ʻia, a hoʻokuʻu ʻia ka wahi o loko i kahi pae o ka vacuum e hōʻemi i ka hoʻoili wela. I loko o ka ʻōnaehana LNG kūloko, he lōʻihi kona manawa hoʻohana, ʻike ʻia ka hopena insulation thermal a me ka nalowale liʻiliʻi o ka ikehu. Eia nō naʻe, ma muli o ke kumukūʻai kiʻekiʻe a me ka manawa hana lōʻihi, hoʻohana nui ʻia i nā papahana koʻikoʻi a ʻaʻole hiki ke hoʻohana ʻia ma ka nui.
Hoʻopaʻa ʻia: ʻO ka hoʻopaʻa ʻana he ʻano hana kuʻuna o ka insulation, ʻo ia hoʻi, hoʻokomo ʻia nā mea insulation porous ma waho o ka paipu, a ua hoʻokō ʻia ka insulation no ka mea ua hoʻopiha ʻia nā cell i ka ea kaomi maʻamau (a i ʻole nā kinoea ʻē aʻe). ʻOi aku ka haʻahaʻa o ka hopena insulation thermal ma mua o ka insulation vacuum, akā he ʻano maʻalahi kona, haʻahaʻa kumu kūʻai, a me ka hana maʻalahi a me ka mālama ʻana. I kēia manawa, hoʻohana ka nui o nā pipeline LNG i kēia ala no ka hoʻokaʻawale ʻana i ka pipeline.
I ka mākeke o kēia manawa, hoʻohana ka nui o nā mea insulation i hoʻopaʻa ʻia i ka polyurethane a me nā mea aniani e like me nā mahana LNG ʻokoʻa. Ke hoʻohālikelike ʻia me nā mea hoʻonaninani wela kahiko e like me ka polyurethane a me ke aniani pahu, ʻoi aku ka maikaʻi o ka melamine foam. Loaʻa i ka melamine foam kahi ākea ākea o ke aniau (e emi mai ka 196 degere Celsius a 200 degere Celsius), mālama i kahi ʻano paʻa kino a me ke kemika ma lalo o ke kūlana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a hāʻawi i ka conductivity thermal maikaʻi loa (thermal conductivity coefficient, 0.032 W / (m * K)) a me ke kani absorption hana (0.95NRC), e hoʻolilo i ke kaumaha LNG mea palekana a me ka palekana o ke kaiapuni.
I ka hoʻolālā ʻenekinia o nā hale kanu LNG, pono e nānā pono ʻia ke kūlana maoli o ka papahana, a pono e koho ʻia a hoʻohana ʻia nā mea hoʻonaninani wela kūpono a me nā mea hoʻonaninani. ʻO kāna mau mea koʻikoʻi he:
- Pono ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka hoʻohana ʻana i ka mahana o nā mea insulation anuanu ma mua o ka haʻahaʻa haʻahaʻa o ka ʻenehana i ka wā o ka hana maʻamau;
- ʻO ka hana pale ahi o nā mea insulation anuanu e kūpono i nā koi o nā kūlana aupuni o kēia manawa;
- E hoʻohana mua i ka hoʻohana ʻana i nā mea insulation anu me ke kūpaʻa maikaʻi o ka wai mahu e hōʻoia i ka paʻa lōʻihi o ka hana waiwai;
- Pono ka mea hoʻoheheʻe anuanu i ka ʻoki ʻana a i ʻole ka ʻoki ʻana i ka hana, hana maʻalahi, a maʻalahi hoʻi ka paʻakikī o ka hoʻonohonoho ʻana ma ka pūnaewele;
- Hāʻawi mua i nā mea waiwai a i ʻole nā huahana me nā pōmaikaʻi hoʻokele waiwai kiʻekiʻe;
- E ho'ēmi i ka nui o ka hana mālama i kēlā me kēia lā ma hope o ka hoʻokomo ʻana i ka ʻōnaehana hoʻomaha a hoʻomaikaʻi i ka hoʻohana hou ʻana i nā mea.
Ma muli o nā koi i luna, hiki ke hoʻohana ʻia ka melamine foam ma ke ʻano he mea hoʻomehana wela a me ka mālama anu no nā pipelines LNG, a he kuleana koʻikoʻi ka melamine foam i ka hoʻomehana wela a me ka mālama anu o nā pipelines LNG. ʻO ka Melamine foam kahi mea palakiko elastomer maʻalahi me kahi ʻano pūnaewele ʻekolu-dimensional. Mālama mau ia i kahi ʻano kino a me ke kemika piha ma minus 196 degere Celsius, no laila he conductivity thermal maikaʻi loa ia i nā mahana haʻahaʻa a kāohi i ka convection o nā wahi o loko a me waho. ʻO ke alakaʻi ʻana a me ka hoʻoili wela radiation, ke kūpaʻa ahi maikaʻi loa (B1, UL94 V0 a me HL-1) a me nā waiwai insulating (ʻaʻole e hana i kekahi static a me antistatic), ke kūpaʻa waikawa a me alkali, ke kūpaʻa corrosion, ke kūpaʻa ʻelemakule, ke kaumaha māmā a me ka haʻahaʻa o ka mahana, a me nā mea ʻē aʻe. hana, a no ka mea he mea elastic akā ʻaʻohe fiber ka melamine resin foam, ʻaʻohe ona lepo, ʻaʻohe halogenated a ʻaʻohe hydrocarbons, nā mea hoʻomau lapalapa a/a i ʻole nā mea hao kaumaha ʻawaʻawa, kūpono loa no nā wahi me nā koi kiʻekiʻe o ke kaiapuni, mālama anu (hale hana lāʻau lapaʻau, hale hana mālama huaʻai a me nā mea kanu, hale hana meaʻai, hale hana ʻiʻo a me ka hale hana inu anu) insulation anuanu (thermal a me ka acoustic insulation), refrigerated/freezer cold insulation (thermal a me ka acoustic insulation), LNG liquefied storage tank cold insulation (thermal a me ka acoustic insulation), LNG liquefied transport vehicle a i ʻole Ship cold a me ka thermal insulation (thermal a me ka acoustic insulation).
