ʻO nā ʻano hana hana Nitrogen e pili ana i ke kaomi swing adsorption, ka wehe ʻana o ka membrane a me ka hoʻokaʻawale ʻana i ka ea cryogenic.ʻO ka mea hana nitrogen he mea hana nitrogen i hoʻolālā ʻia a hana ʻia e like me ka ʻenehana adsorption pressure swing.Hoʻohana ka mīkini nitrogen i ka kānana molekala kalapona i lawe ʻia ma ke ʻano he adsorbent a hoʻohana i ke kumu o ka lumi hoʻoluliluli swing adsorption e hoʻokaʻawale i ka ea no ka hoʻopuka ʻana i ka nitrogen maʻemaʻe kiʻekiʻe.ʻO ka maʻamau, ʻelua mau hale kiaʻi adsorption i hoʻohui like ʻia, a ʻo ka PLC i lawe ʻia e hoʻomalu i ka hana maʻalahi o ka valve pneumatic i lawe ʻia mai e hoʻokō i ka adsorption pressurized a me ka decompression regeneration e hoʻopau i ka hoʻokaʻawale ʻana o ka nitrogen a me ka oxygen a loaʻa ka pono kiʻekiʻe-maʻemaʻe nitrogen.
ʻO ke ala mua ka hana ʻana o ka nitrogen ma ka hana cryogenic
Hoʻopili mua kēia ʻano hana i ka ea, a laila liquefies ka ea.Ke hoʻohana nei i nā ʻāpana paila like ʻole o ka oxygen a me nā ʻāpana nitrogen, ke kinoea a me ka hoʻopili wai ma ka pā o ke kolamu distillation no ka hoʻololi nui a me ka wela.ʻO ka oxygen me kahi kiʻekiʻe e hoʻolapalapa ʻia e hoʻomau mau ʻia mai ka mahu i loko o kahi wai, a ʻo ka nitrogen me ka haʻahaʻa e hoʻolapalapa ʻia e hoʻoneʻe mau ʻia i ka mahu, no laila e hoʻonui mau ʻia ka maʻiʻo nitrogen i loko o ka mokuahi piʻi, ʻoiai ka ʻike o ka oxygen i lalo. ʻoi aku ka kiʻekiʻe o ka wai.No laila, hoʻokaʻawale ʻia ka oxygen a me ka nitrogen no ka loaʻa ʻana o ka nitrogen a i ʻole oxygen.Hana ʻia kēia ʻano hana ma kahi mahana haʻahaʻa ma mua o 120K, no laila ua kapa ʻia ʻo cryogenic air separation.
ʻO ka lua, ʻo ia ka hoʻohana ʻana i ke kaomi swing adsorption e hana i ka nitrogen
Pressure swing adsorption kaʻina mea e selectively adsorb oxygen a me naikokene mea i loko o ka lewa ma adsorbent, a hoʻokaʻawale i ka lewa e loaʻa naikokene.Ke hoʻopili ʻia ka ea a hele i ka papa adsorption o ka hale kiaʻi adsorption, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i nā molekala oxygen, a noho nā molekala nitrogen i loko o ka māhele kinoea e lilo i nitrogen.Ke hiki ka adsorption i ke kaulike, ua hoʻoneʻe ʻia nā molekala oxygen i hoʻopili ʻia ma ka ʻili o ka molecular sieve e ka decompression e hoʻihoʻi i ka mana adsorption o ka sieve molecular, ʻo ia hoʻi, adsorbent analysis.I mea e hoʻolako mau ai i ka nitrogen, ua hoʻolako pinepine ʻia ka ʻāpana me ʻelua a ʻoi aku paha nā hale kiaʻi adsorption, hoʻokahi no adsorption a ʻo kekahi no ka nānā ʻana, a hoʻololi ʻia no ka hoʻohana ʻana i ka manawa kūpono.
ʻO ke ala ʻekolu ka hana ʻana i ka nitrogen ma ka wehe ʻana o ka membrane
ʻO ke ʻano o ka hoʻokaʻawale ʻana o ka membrane ka hoʻokaʻawale ʻana i ke kinoea waiwai nui mai ke kinoea hui ʻia me ka hoʻohana ʻana i ka koho permeability o ka membrane polymerization organik.ʻO ka mea kiʻiʻoniʻoni kūpono e loaʻa i ke koho kiʻekiʻe a me ka permeability kiʻekiʻe.No ka loaʻa ʻana o kahi kaʻina hana hoʻokele waiwai, pono kahi membrane hoʻokaʻawale polymer lahilahi, no laila pono ke kākoʻo.ʻO ka maʻamau o nā projectiles piercing armor ka mea maʻamau i nā projectiles piercing armor a me nā projectiles hollow fibre armor piercing projectiles.Ma kēia ʻano, inā nui ka hana kinoea, ʻoi aku ka nui o ka ʻāpana kiʻiʻoniʻoni i makemake ʻia a kiʻekiʻe ke kumukūʻai kiʻiʻoniʻoni.ʻO ke ala hoʻokaʻawale membrane he mea maʻalahi a maʻalahi ka hana, akā ʻaʻole i hoʻohana nui ʻia i ka ʻoihana.
I ka hōʻuluʻulu ʻana, ʻo ka mea i luna ka mea nui o nā ʻano hana o ka nitrogen.ʻO ka hoʻokaʻawale ʻana o ka ea Cryogenic hiki ke hoʻohua ʻaʻole wale ka nitrogen, akā hiki ke mālama ʻia i loko o ka pahu mālama wai nitrogen.ʻOi aku ka nui ma mua o hoʻokahi makahiki ka pōʻaiapuni o ka hana ʻana o ka cryogenic nitrogen, no laila ʻaʻole i noʻonoʻo ʻia nā mea hana standby no ka hana cryogenic nitrogen.ʻO ke kumu o ka hana ʻana o ka nitrogen ma ka hoʻokaʻawale ʻana o ka ea membrane ʻo ia ke komo ʻana o ka ea i ka kānana polymer membrane ma hope o ka kānana ʻia e ka compressor.Ma muli o ka ʻokoʻa o ka solubility a me ka diffusion coefficient o nā kinoea like ʻole i loko o ka membrane, ʻokoʻa ka helu permeation pili i nā membrane kinoea like ʻole.Ke ʻoi aku ka maʻemaʻe o ka nitrogen ma mua o 98%, ʻoi aku ke kumukūʻai ma mua o 15% kiʻekiʻe ma mua o ka PSA nitrogen generator o ka kikoʻī like.
