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 anu hohonu 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 oxygen wai ma o ke kumu o ke kaomi, refrigeration a me ka distillation haʻahaʻa haʻahaʻa.
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 hoʻolālā maʻalahi, ʻaʻohe kīwaha hoʻololi, liʻiliʻi liʻiliʻi, a me nā mea ʻē aʻe, akā no ka mea e hilinaʻi nui ʻia ka mea membrane i ka lawe ʻana mai, ʻoi aku ke kumukūʻai o kēia manawa a ua haʻahaʻa ka helu penetration, no laila ua hoʻohana nui ʻia ia no nā kumu kūikawā o ka kahe liʻiliʻi, e like me ka mīkini hana nitrogen mobile.
ʻO ka molecular sieve pressure adsorption method (PSA) ka ea e like me ka mea maka, carbon molecular sieve e like me adsorbent, ka hoʻohana ʻana i ke kumu adsorption pressure, ka hoʻohana ʻana i ka kānana molekole kalapona no ka oxygen a me ka nitrogen adsorption a me ka oxygen a me ke ʻano hoʻokaʻawale ʻana. hale kiaʻi, pono e hoʻomaloʻo ʻia ka wai i ka lewa e hōʻemi i ka ʻino ʻana o ka wai ma ka molecular sieve a hoʻolōʻihi i ke ola o ka molecular sieve I ke kaʻina hana PSA nitrogen maʻamau, hoʻohana pinepine ʻia ka hale hoʻomaloʻo e wehe i ka wai ma ka lewa.
