ʻO Nitrogen generator he mea hana hana nitrogen i hoʻolālā ʻia a hana ʻia e like me ka ʻenehana PSA. Hoʻohana ʻo Nitrogen generator i ka kānana molekele kalapona (CMS) ma ke ʻano adsorbent. Hoʻohana maʻamau i ʻelua mau hale kiaʻi adsorption i ka like, e hoʻomalu i ka inlet pneumatic valve i hoʻohana ʻia e ka inlet PLC, alternately pressurized adsorption a me ka decompressing regeneration, hoʻopau i ka nitrogen a me ka hoʻokaʻawale oxygen, e kiʻi i ka nitrogen maʻemaʻe e pono ai.
ʻO nā mea maka o ka kānana molekala kalapona he resin phenolic, pulverized mua a hui pū me ka mea kumu, a laila hoʻāla ʻia nā pores. Hoʻokaʻawale ka ʻenehana PSA i ka nitrogen a me ka oxygen e ka van der Waals ikaika o carbon molecular sieve, no laila, ʻoi aku ka nui o ka ʻili, ʻoi aku ka like o ka puʻupuʻu pore, a ʻoi aku ka nui o nā pores a i ʻole subpores, ʻoi aku ka nui o ka hiki adsorption.
