Loaʻa nā mea hana hana Nitrogen ma ka hoʻokaʻawale ʻana i ka ea a me ka nitrogen mai kahi mea maka e hoʻohana ana i ka ea ma ke ʻano he mea maka.
ʻEkolu ʻano o ka naikokene ʻoihana:
◆Cryogenic ea hoʻokaʻawale nitrogen
ʻO ka Cryogenic ea hoʻokaʻawale ʻana i ke ea he ʻano hana hana nitrogen kuʻuna i hana ʻia i nā makahiki i hala iho nei.Hoʻohana ʻo ia i ka ea ma ke ʻano he mea maka, hoʻopili ʻia, hoʻomaʻemaʻe ʻia, a laila hoʻohana i ka hoʻololi wela e hoʻoheheʻe i ka ea i loko o ka ea wai.ʻO ka ea wai ka nui o ka hui ʻana o ka oxygen wai a me ka nitrogen wai, nona nā ʻano paila like ʻole o ka oxygen wai a me ka nitrogen wai (ʻo ka paila o ka mua he -183 ° C ma 1 atm, a ʻo ka hope -196 ° C) , a me ka distillation ma o ka ea wai E hoʻokaʻawale iā lākou no ka loaʻa ʻana o ka nitrogen.ʻO ka cryogenic air separation nitrogen production equipment paʻakikī, uhi i kahi nui, he kiʻekiʻe ke kumu kūʻai kālā, a he waiwai nui i nā lako, kiʻekiʻe ke kumukūʻai hana, hana haʻahaʻa haʻahaʻa (12 a 24 mau hola), nā koi hoʻonohonoho kiʻekiʻe a me ka lōʻihi lōʻihi.ʻO nā lako piha, hoʻonohonoho a me nā kumu waiwai, nā mea hana ma lalo o 3500Nm3 / h, ʻo ka nui o ka hoʻopukapuka ʻana o nā lako PSA o nā kikoʻī like ʻo 20% ~ 50% haʻahaʻa ma mua o ka cryogenic air separation unit.ʻO ka cryogenic air separation nitrogen mea kanu ua kūpono no ka nui-scale naikokene hana hana, aʻo ka medium a me ka liʻiliʻi naikokene hana mea uneconomical.

◆Molecular sieve nitrogen
ʻO kahi ʻano e hoʻohana ʻia ai ka ea ma ke ʻano he mea maka, hoʻohana ʻia kahi kānana molekala kalapona ma ke ʻano he adsorbent, hoʻohana ʻia kahi kumu hoʻoheheʻe kaomi ʻana, a hoʻohana ʻia kahi adsorption koho o ka oxygen a me ka nitrogen e kahi kānana molekala kalapona e hoʻokaʻawale i ka nitrogen a me ka oxygen. Ua kapa ʻia ʻo PSA nitrogen production.ʻO kēia ʻano hana he ʻenehana hana nitrogen hou i hoʻomohala wikiwiki ʻia i nā makahiki 1970.Hoʻohālikelike ʻia me ke ʻano hana hana nitrogen kuʻuna, he kaʻina maʻalahi, kiʻekiʻe kiʻekiʻe o ka automation, wikiwiki ka hana kinoea (15 a 30 mau minuke), haʻahaʻa haʻahaʻa ikehu, hiki ke hoʻoponopono ʻia ka maʻemaʻe o ka huahana e like me nā pono o ka mea hoʻohana ma kahi ākea, hana maʻalahi a mālama. , hana ʻO ke kumu kūʻai haʻahaʻa a me ka hiki ke hoʻololi ikaika o ka mea hana, no laila ke hoʻokūkū nei i nā mea hana hana nitrogen ma lalo o 1000Nm3 / h.ʻOi aku ka kaulana i waena o nā mea hoʻohana nitrogen liʻiliʻi a me waena.Ua lilo ʻo PSA nitrogen i koho mua no nā mea hoʻohana liʻiliʻi a me nā mea hoʻohana nitrogen.ʻano hana.

◆Membrane ea hoʻokaʻawale nitrogen
Hoʻohana ʻia ka ea ma ke ʻano he mea maka, a ma lalo o nā kūlana paʻi like ʻole, loaʻa nā kinoea o nā waiwai like ʻole e like me ka oxygen a me ka nitrogen i nā helu permeation like ʻole i ka membrane e hoʻokaʻawale i ka oxygen a me ka nitrogen.Hoʻohālikelike ʻia me nā mea hana nitrogen ʻē aʻe, ʻoi aku ka maikaʻi o ka hoʻolālā maʻalahi, ka liʻiliʻi liʻiliʻi, ʻaʻohe kīwaha hoʻololi, ka liʻiliʻi o ka mālama ʻana, ʻoi aku ka wikiwiki o ka hana kinoea (≤3 mau minuke), hiki ke hoʻonui i ka hiki, a me nā mea ʻē aʻe kūpono no ka hoʻomaʻemaʻe nitrogen ≤ 98 Loaʻa i ka % o nā mea hoʻohana naikokene liʻiliʻi a me ke kumu kūʻai maikaʻi loa.Ke ʻoi aku ka maʻemaʻe o ka nitrogen ma luna o 98%, ʻoi aku ia ma mua o 15% kiʻekiʻe ma mua o ka PSA nitrogen-making mea hana like.
