Pressure swing adsorption nitrogen production

hoʻohana i ka ea e like me ka mea maka, carbon molecular sieve e like me ka adsorbent, me ka hoʻohana ʻana i ke kumu o ka adsorption swing adsorption, ka hoʻohana ʻana i ke kānana mole kalapona e koho i ka oxygen a me ka nitrogen e hoʻokaʻawale i ka nitrogen a me ka oxygen, i ʻike ʻia ʻo PSA nitrogen.ʻO kēia ʻano hana he ʻenehana hana nitrogen hou i hoʻomohala wikiwiki i nā makahiki 1970.Ke hoʻohālikelike ʻia me ke ʻano hana hana nitrogen kuʻuna, loaʻa iā ia nā pōmaikaʻi o ke kahe kaʻina maʻalahi, kiʻekiʻe kiʻekiʻe o ka automation, ka hana kinoea wikiwiki (15-30 mau minuke), ka hoʻohana haʻahaʻa haʻahaʻa, hiki ke hoʻoponopono ʻia ka maʻemaʻe o ka huahana ma kahi ākea nui e like me nā pono o ka mea hoʻohana. ʻO ka hana a me ka mālama ʻana he mea maʻalahi, a me ka hana Me nā hiʻohiʻona o ke kumu kūʻai haʻahaʻa a me ka adaptability ikaika, ʻoi aku ka hoʻokūkū ma nā mea hana nitrogen ma lalo o 1000Nm3 / h, a ʻoi aku ka kaulana me nā mea hoʻohana liʻiliʻi a me nā mea hoʻohana.Ua lilo ʻo PSA nitrogen production i koho mua no nā ʻano mea hoʻohana liʻiliʻi a me waena.

Cryogenic Air Separation Nitrogen

ʻO ka hana ʻana o ka nitrogen Cryogenic e ka hoʻokaʻawale ʻana i ka ea he ʻano hana hana nitrogen kuʻuna me ka mōʻaukala o kekahi mau makahiki.Hoʻohana ia i ka ea ma ke ʻano he mea maka, hoʻopili ʻia a hoʻomaʻemaʻe ʻia, a laila hoʻohana i ka hoʻololi wela e hoʻoheheʻe i ka ea i loko o ka ea wai.ʻO ka Air Liquide ka mea nui o ka hui ʻana o ka oxygen wai a me ka nitrogen wai, me ka hoʻohana ʻana i nā wahi paila like ʻole o ka oxygen wai a me ka nitrogen wai (ma ka lewa 1, ʻo ka paila o ka mua he -183 ° C, a ʻo ka hope -196 ° C) , ma o ka rectification o Liquid Air, E hoʻokaʻawale iā lākou no ka loaʻa ʻana o ka nitrogen.Cryogenic ea hoʻokaʻawale nitrogen hana lako mea paʻakikī, uhi i ka nui wahi, kiʻekiʻe nā kumu waiwai, oi hoʻokahi-manawa lako waiwai hoʻolimalima, kiʻekiʻe hana koina, lohi kinoea hana (12-24h), kiʻekiʻe hoʻouka koi, a me ka lōʻihi pōʻaiapuni.ʻO nā mea hana piha, hoʻokomo a me nā kumu waiwai, nā mea hana ma lalo o 3500Nm3 / h, ʻo ka nui o ka hoʻopukapuka ʻana o ka hāmeʻa PSA o ka kikoʻī like he 20% -50% haʻahaʻa ma mua o ka mea hoʻokaʻawale ea cryogenic.Cryogenic ea hoʻokaʻawale nitrogen hana lako mea kūpono no ka nui-scale naikokene hana hana, oiai me ka liʻiliʻi a me ka liʻiliʻi naikokene hana uneconomical.

ʻO ka hoʻokaʻawale ʻana i ka ea o ka membrane ea

ʻO ka hoʻohana ʻana i ka ea e like me ka mea maka, ma lalo o kekahi mau kūlana paʻi, ʻo ka hoʻohana ʻana i ka oxygen a me ka nitrogen a me nā kinoea ʻē aʻe me nā waiwai like ʻole i loko o ka membrane he ʻokoʻa nā helu permeation e hoʻokaʻawale i ka oxygen a me ka nitrogen.Ke hoʻohālikelike ʻia me nā mea hana hana nitrogen ʻē aʻe, loaʻa iā ia nā pōmaikaʻi o ka hana maʻalahi, ka liʻiliʻi liʻiliʻi, ʻaʻohe kīwaha hoʻololi, ka liʻiliʻi o ka mālama ʻana, ʻoi aku ka wikiwiki o ka hana kinoea (≤3 mau minuke), a me ka hoʻonui ʻana i ka hiki.He kūpono ia no ka hoʻomaʻemaʻe nitrogen ≤ 98% o nā mea hoʻohana liʻiliʻi a me nā mea hoʻohana i ka lākiō maikaʻi loa.Ke ʻoi aku ka maʻemaʻe o ka nitrogen ma luna o 98%, ʻoi aku kona kumukūʻai ma mua o 15% kiʻekiʻe ma mua o ka PSA nitrogen generator o ka kikoʻī like.
