1. Ka nānā 'ana i nā mea hana nitrogen ma'ema'e ki'eki'e
ʻO nā mea hana nitrogen maʻemaʻe kiʻekiʻe ka mea nui o ka ʻōnaehana cryogenic air separation (cryogenic air separation). Hoʻohana nui ʻia e hoʻokaʻawale a hoʻomaʻemaʻe i ka nitrogen mai ka ea, a loaʻa i ka hopena nā huahana nitrogen me ka maʻemaʻe a hiki i **99.999% (5N) a i ʻole ke kiʻekiʻe. Hoʻokumu ʻia nā mea hana ma ka ** cryogenic distillation ** ʻenehana, me ka hoʻohana ʻana i ka ʻokoʻa paila ma waena o ka nitrogen (kahi paila -195.8 ℃) a me ka oxygen (kahi paila -183 ℃) i ka lewa, a loaʻa i ka hoʻokaʻawale maikaʻi ʻana ma o ka condensation haʻahaʻa a me ka fractionation.
Hoʻohana nui ʻia nā mea hana nitrogen kiʻekiʻe i ka uila, ka ʻoihana kemika, ka lāʻau lapaʻau, ka hana metala, ka mālama ʻana i ka meaʻai a me nā ʻoihana ʻē aʻe, ʻoi aku hoʻi i nā ʻoihana ʻenehana kiʻekiʻe e like me ka semiconductor manufacturing a me ka hana pākaukau lithium, he mau koi kiʻekiʻe loa no ka hoʻomaʻemaʻe nitrogen.
2. Nā hiʻohiʻona koʻikoʻi o nā mea hana nitrogen maʻemaʻe kiʻekiʻe
1). Ultra-kiʻekiʻe maʻemaʻe nitrogen puka
- Hiki i ka hale kiaʻi distillation multi-stage a me ke kiʻekiʻe o ka molecular sieve adsorption ʻenehana hiki ke hana i ka 99.999% ~ 99.9999% (5N ~ 6N) kiʻekiʻe-maʻemaʻe nitrogen e hoʻokō i nā koi ikaika o semiconductor, photovoltaic a me nā ʻoihana ʻē aʻe.
- Hoʻopau hou ʻia ka ʻike ʻana i ka oxygen, moisture a me nā hydrocarbons ma o ka cryogenic adsorption (PSA) a i ʻole ka ʻenehana deoxygenation catalytic e hōʻoia i ka hoʻomaʻemaʻe ʻana o ka nitrogen i ka maʻamau.
2). E mālama i ka ikehu a maikaʻi, hana paʻa
- Ke hoʻohana nei nā mea hoʻokaʻawale ea cryogenic i ka expander + heat exchanger e hoʻonui i ka pōʻai refrigeration a hōʻemi i ka hoʻohana ʻana i ka ikehu. Ke hoʻohālikelike ʻia me ka ʻenehana hoʻokaʻawale ʻana o ka membrane a i ʻole kaomi ʻana i ka ʻenehana adsorption (PSA), ʻoi aku ka haʻahaʻa o ke kumukūʻai hana lōʻihi.
- Mālama ka ʻōnaehana hoʻokele automated i ka mahana, kaomi a me ka maʻemaʻe i ka manawa maoli e hōʻoia i ka hana paʻa o nā mea hana a hōʻemi i ka hana lima.
3). Hoʻolālā modular, hiki ke hoʻololi ikaika
- ʻO ka liʻiliʻi (<100Nm³ / h), waena (100 ~ 1000Nm³ / h) a i ʻole ka nui (> 1000Nm³ / h) hiki ke hoʻonohonoho pono ʻia nā mea hana nitrogen e like me nā pono o ka mea kūʻai aku, hiki ke hoʻohālikelike i nā pono o nā ʻoihana like ʻole.
- He kūpono no ka hoʻokumu ʻana i ka nitrogen ma ka pūnaewele (On-site Generation), e hōʻemi ana i ka lawe ʻana a me ka mālama ʻana i nā kumukūʻai o ka wai nitrogen.
4). Palekana a hilinaʻi, pili kaiapuni a me ka hoʻohana haʻahaʻa
- Hoʻohana i ka hoʻolālā pahū a me nā pale palekana he nui (e like me ka nānā ʻana i ka oxygen content, overpressure protection) e hōʻoia i ka hana palekana.
- Hoʻopau wale ʻia ka uila a me ka ea i ka wā o ka hoʻokaʻawale ʻana o ke ea anu hohonu, me ka ʻole o ka pollution kemika, e like me nā kūlana hana ʻōmaʻomaʻo.
3. ʻO nā wahi noi nui o nā lako nitrogen maʻemaʻe kiʻekiʻe
1). ʻOihana uila a me semiconductor
- Hoʻohana ʻia i ka hana wafer, LED packaging, photovoltaic cell production, e hāʻawi ana i ka nitrogen maʻemaʻe ultra-kiʻekiʻe e like me ke kinoea pale e pale ai i ka oxidation a me ka pollution.
- Ma ka semiconductor etching, chemical vapor deposition (CVD) a me nā kaʻina hana ʻē aʻe, hoʻohana ʻia ka nitrogen ma ke ʻano he mea lawe kinoea a hoʻomaʻemaʻe paha e hōʻoia i ka paʻa o ka hana.
2). ʻOihana Kimia a me ka ikehu
- Hoʻohana ʻia no ka pale ʻana i ke kinoea inert i nā ʻoihana kemika a me ka lanahu e pale ai i nā pōʻino a me ka pahū.
- Hoʻohana ʻia i ka hana pākaukau lithium (e like me ka hoʻomaloʻo ʻana i ka ʻāpana pole, ka hoʻopili ʻana i ka wai wai) e pale ai i ka makū a me ka oxygen mai ka hoʻopili ʻana i ka hana pākaukau.
3). ʻOihana meaʻai a me nā lāʻau lapaʻau
- Hoʻohana ka ʻeke meaʻai i ka nitrogen maʻemaʻe kiʻekiʻe (ʻoi aku ma mua o 99.9%) e hoʻolōʻihi i ke ola o ka papa a pale i ka oxidation a me ka pōʻino.
- Hoʻohana ʻia i ka ʻoihana lāʻau lapaʻau no ka hoʻopiha piha ʻana i ka nitrogen aseptic a me ka pale ʻana i nā mea ola, e like me nā kūlana GMP.
4). Hoʻomaʻamaʻa wela metala a paʻi 3D
- Hāʻawi i kahi kaiapuni inert i ka annealing, quenching, brazing a me nā kaʻina hana ʻē aʻe e pale ai i ka hoʻoheheʻe metala.
- Hoʻohana ʻia no ka paʻi metala 3D (ʻenehana SLM) e hōʻemi i ka pauka oxidation a hoʻomaikaʻi i ka maikaʻi.
5). ʻImi ʻepekema a me Laboratory
- Hāʻawi i kahi kaiapuni nitrogen maʻemaʻe kiʻekiʻe loa no nā hoʻokolohua kiʻekiʻe e like me nā mea superconducting a me ka nuclear magnetic resonance (NMR).
4. Nā ʻano hoʻomohala e hiki mai ana
1). ʻIke a me ka hoʻohui pūnaewele o nā mea (IoT).
- E hoʻomaikaʻi i ka pono o ka ikehu a me ka hiki ke mālama i ka wānana ma o ka nānā mamao a me ka loiloi AI.
2). ʻenehana ʻōmaʻomaʻo a haʻahaʻa-carbon
- Hoʻohui pū ʻia me ka ikehu hou (e like me ka mana makani, photovoltaic) lako mana e hōʻemi i ka wāwae kalapona.
3). Miniaturization a me ka mobile nitrogen hana
- E hoʻomohala i nā lako hana hana cryogenic nitrogen ʻoi aku ka maikaʻi no ka hāʻawi ʻana i ka ikehu a me nā hale liʻiliʻi.
Hōʻuluʻulu manaʻo
Ma ke ʻano he noi nui o ka ʻenehana hoʻokaʻawale ea cryogenic, ua lilo nā mea hana nitrogen maʻemaʻe kiʻekiʻe i nā lako kumu o ka hana ʻenehana kiʻekiʻe a me ka hana ʻenehana me kāna mau pono o ka maʻemaʻe ultra-kiʻekiʻe, mālama i ka ikehu a me ka paʻa, palekana a me ka pale o ke kaiapuni. Me ka hoʻomohala wikiwiki ʻana o nā ʻoihana e like me ka uila a me ka ikehu hou, e hoʻomau ka hoʻomohala ʻana o nā mea hana nitrogen maʻemaʻe kiʻekiʻe i ka naʻauao, ka pono a me ka ʻōmaʻomaʻo, e hāʻawi ana i nā hopena nitrogen hilinaʻi no ka ʻoihana hou.
No nā pono oxygen/nitrogen/argon, e ʻoluʻolu e kelepona mai iā mākou:
