ʻO ka kānana molekala hana naikokene

Ma ke kahua ʻoihana, hoʻohana nui ʻia ka mea hana nitrogen i ka ʻoihana petrochemical, liquefaction kinoea kūlohelohe, metallurgy, meaʻai, lāʻau lapaʻau a me nā ʻoihana uila. Hiki ke hoʻohana ʻia nā huahana nitrogen o ka mea hana nitrogen ma ke ʻano he kinoea mea hana, akā ma ke ʻano he mea maka ʻoihana a me ka refrigerant, he mea pono ia no ka lehulehu i ka hana ʻoihana. Ua māhele nui ʻia ke kaʻina hana o ka mea hana nitrogen i ʻekolu ʻano: ke ʻano hoʻokaʻawale ea anuanu hohonu, ke ʻano hoʻokaʻawale membrane a me ke ʻano adsorption hoʻololi kaomi sieve molecular (PSA).
ʻO ke ʻano hoʻokaʻawale ea anuanu hohonu ka hoʻohana ʻana i ke kumumanaʻo paila like ʻole o ka oxygen a me ka naikokene i ka lewa, a me ka hana ʻana o ka naikokene wai a me ka oxygen wai ma o ke kumumanaʻo o ka hoʻopili ʻana, ka hoʻomaʻalili ʻana a me ka distillation wela haʻahaʻa". Hiki i kēia ʻano hana ke hana i ka naikokene wai wela haʻahaʻa a me ka oxygen wai, me ka nui o ka hana ʻana; ʻo ka hemahema he nui ka hoʻopukapuka kālā, hoʻohana nui ʻia i ke koi naikokene a me ka oxygen i ka metallurgy a me ka ʻoihana kemika.
ʻO ke ʻano hoʻokaʻawale membrane ka ea ma ke ʻano he mea maka, ma lalo o kekahi mau kūlana kaomi, e hoʻohana ana i ka oxygen a me ka naikokene i loko o ka membrane me nā helu permeability like ʻole e hana i ka hoʻokaʻawale oxygen a me ka naikokene? Loaʻa i kēia ʻano hana nā pono o ke ʻano maʻalahi, ʻaʻohe valve hoʻololi, ka nui liʻiliʻi, a pēlā aku, akā no ka mea e hilinaʻi nui ʻia ka mea membrane i nā mea lawe mai, he pipiʻi ke kumukūʻai o kēia manawa a he haʻahaʻa ka helu komo ʻana, no laila hoʻohana nui ʻia no nā kumu kūikawā o ke kahe liʻiliʻi, e like me ka mīkini hana naikokene kelepona.
ʻO ke ʻano hana adsorption kaomi kānana molekala (PSA) ka lewa ma ke ʻano he mea maka, ka kānana molekala kalapona ma ke ʻano he adsorbent, ka hoʻohana ʻana i ke kumumanaʻo adsorption kaomi, ka hoʻohana ʻana i ka kānana molekala kalapona no ka adsorption oxygen a me ka nitrogen a me ke ʻano hoʻokaʻawale oxygen a me ka nitrogen ". Loaʻa i kēia ʻano hana nā ʻano o ke kahe hana maʻalahi, ke kiʻekiʻe o ka automation, ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka maʻemaʻe nitrogen kiʻekiʻe, a ʻo ia ka ʻenehana i hoʻohana nui ʻia. Ma mua o ke komo ʻana o ka lewa i loko o ka hale kiaʻi adsorption kanaka, pono e hoʻomaloʻo ʻia ka wai i ka lewa e hōʻemi i ka ʻino o ka wai ma ka kānana molekala a hoʻolōʻihi i ke ola lawelawe o ka kānana molekala. I ke kaʻina hana hana nitrogen PSA maʻamau, hoʻohana pinepine ʻia ka hale kiaʻi maloʻo e wehe i ka makū i ka lewa. Ke hoʻopiha ʻia ka hale kiaʻi maloʻo me ka wai, puhi ʻia ka hale kiaʻi maloʻo me ka ea maloʻo e ʻike i ka hana hou ʻana o ka hale kiaʻi maloʻo.
