ʻO ke kānana molecular hana Nitrogen

I ka ʻoihana ʻoihana, hoʻohana nui ʻia ka mea hana nitrogen i ka petrochemical, kūlohelohe kinoea liquefaction, metallurgy, meaʻai, lāʻau lapaʻau a me ka ʻoihana uila. Hiki ke hoʻohana ʻia nā huahana nitrogen o ka mea hoʻoheheʻe nitrogen e like me ke kinoea mea hana, akā e like me nā mea hana ʻenehana a me ka refrigerant, he mea pono e pono ai ka lehulehu i ka hana ʻoihana. Hoʻokaʻawale ʻia ke kaʻina hana o ka mea hana nitrogen i ʻekolu mau ʻano: ka hoʻokaʻawale ʻana i ke ea anuanu, ke ʻano hoʻokaʻawale membrane a me ka molecular sieve pressure change adsorption method (PSA).
ʻO ke ʻano o ka hoʻokaʻawale ʻana o ka ea anuanu, ʻo ia ka hoʻohana ʻana i ke kumu hoʻoheheʻe ʻokoʻa o ka oxygen a me ka nitrogen i ka lewa, a me ka hana ʻana o ka wai nitrogen a me ka wai oxygen ma o ke kumu o ka hoʻoemi, refrigeration a me ka distillation haʻahaʻa haʻahaʻa ". Hiki i kēia ʻano hana ke hana i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa wai nitrogen a me ka wai oxygen, ʻano hana nui; ʻO ka hemahema ka waiwai nui, hoʻohana maʻamau i ka nitrogen a me ka koi oxygen i ka metallurgy a me ka ʻoihana kemika.
ʻO ke ʻano o ka hoʻokaʻawale ʻana o ka membrane ka lewa e like me ka mea maka, ma lalo o kekahi mau pilikia, e hoʻohana ana i ka oxygen a me ka nitrogen i loko o ka membrane me nā helu permeability like ʻole e hoʻokaʻawale i ka oxygen a me ka nitrogen. Loaʻa i kēia ʻano ka maikaʻi o ka hana maʻalahi, ʻaʻohe kīwaha hoʻololi, liʻiliʻi liʻiliʻi, a me nā mea ʻē aʻe. kahe liʻiliʻi, e like me ka mīkini hana hana naikokene.
ʻO ka molecular sieve pressure adsorption method (PSA) ʻo ia ka ea e like me ka mea maka, carbon molecular sieve e like me adsorbent, ka hoʻohana ʻana i ke kumu adsorption puʻe, ka hoʻohana ʻana i ka kānana mole kalapona no ka oxygen a me ka nitrogen adsorption a me ka oxygen a me ke ʻano hoʻokaʻawale ʻana ". Loaʻa i kēia ʻano nā hiʻohiʻona o ke kahe kaʻina maʻalahi, kiʻekiʻe kiʻekiʻe o ka automation, ka hoʻohana haʻahaʻa haʻahaʻa a me ka hoʻomaʻemaʻe nitrogen kiʻekiʻe, a ʻo ia ka ʻenehana i hoʻohana nui ʻia. Ma mua o ka komo ʻana o ka ea i ka hale kiaʻi adsorption kanaka, pono e hoʻomaloʻo ʻia ka wai i ka lewa e hōʻemi i ka ʻino o ka wai ma ka sieve molecular a hoʻonui i ke ola lawelawe o ka sieve molecular. Ma ke kaʻina hana hana naikokene PSA maʻamau, hoʻohana mau ʻia ka hale kiaʻi maloʻo e wehe i ka makū o ka lewa. Ke hoʻopihaʻia ka hale kiaʻi maloʻo i ka wai, e puhiʻia ka hale kiaʻi maloʻo me ka ea maloʻo eʻike i ka hoʻoulu houʻana o ka hale kiaʻi maloʻo.
