He mea koʻikoʻi nā kānana molekala zeolite i ka -kaʻina hoʻomaʻemaʻe mua o ka ʻoihana hoʻokaʻawale ea cryogenic. Pono ke kahawai ea e hele i loko o ka mole mole sieve moena ma mua o ke komo ʻana i ka ʻāpana hoʻokaʻawale ea nui, e wehe i nā mea haumia e hoʻopilikia i ke kaʻina cryogenic a i ʻole ka hopena i ka maikaʻi o ka huahana.
He aha ka Cryogenic Air Separation Technology?
Hoʻokumu ʻia ka ʻenehana hoʻokaʻawale ʻana o ka ea Cryogenic ma luna o nā ʻokoʻa i loko o nā wahi paila o nā kinoea constituent, e hoʻomaha mua i ka ea i kahi mahana haʻahaʻa loa (haʻahaʻa ma mua o ka paila o kēlā me kēia ʻāpana kinoea), maʻamau ma lalo o -180 degere, a laila hoʻohana i ka ʻokoʻa paila e hoʻokaʻawale a hoʻokaʻawale i nā kinoea.
Hoʻohana nui ʻia ka ʻenehana hoʻokaʻawale ea Cryogenic i ke kila, kemika, uila, lāʻau lapaʻau, aerospace a me nā ʻano ʻē aʻe. ʻO ia ke ʻano kumu no ka hoʻokaʻawale ʻana i nā kinoea ʻenehana, a ʻo ia ke ala ʻoi loa a maikaʻi loa no ka hana ʻana o ka oxygen, nitrogen, argon a me nā kinoea laha.
Kaʻina Hoʻokaʻawale Ea Cryogenic Distillation
ʻO ka hoʻokaʻawale ʻana i ka ea Cryogenic ke kaʻina hana maʻamau i nā ʻanuʻu ʻeono:
Hoʻopili ʻia ka ea: E kaomi i ka ea ma nā ʻanuʻu he nui o nā compressors, e hāʻawi i ke kaomi pono no ka hoʻoluʻu ea a me ka hoʻokaʻawale ʻana. Hiki ke 0.5Mpa ~ 0.8Mpa (mea paʻi maʻamau), a i ʻole 3Mpa ~ 6Mpa (mehana kiʻekiʻe).
Mamua -hooluolu: E hoemi i ka wela o ka ea a hiki i ke kiko wai e ka mea hooluolu (ka wai hooluolu a i ole ka mea hoohuoi), ma kahi o 5 degere a 10 degere, e hoemi ana i ka ikehu o ka hemo ana o ka ea cryogenic.
Mamua -hoomaemae: E hoohana i na halekiai adsorption (hookomoia me na sieves molecular, alumina i hoalaia a me na adsorbents e ae) no ka wehe ana i na mea haumia e like me ka wai, carbon dioxide a me hydrocarbons, e pale ana i ka ha'aha'a -e hookuku ana i na mea hana, me ka palekana o ka hana cryogenic.
ʻO ka hoʻoluʻu hohonu: Hoʻololi ka ea i hoʻomaʻemaʻe ʻia i ka wela me ke kahe ʻana o ke ea, e hoʻoluʻu mālie i ka mahana liquefaction, ma kahi o -170 degere a -180 degere, a ua hoʻoheheʻe ʻia kekahi o ke kinoea i ka lewa.
Hoʻokaʻawale hoʻoheheʻe: Hoʻokaʻawale ke kolamu kaomi kiʻekiʻe i ka wai momona -oxygen a me ka wai waiwai-naikokene. Loaʻa ka oxygen maʻemaʻe kiʻekiʻe a me ka nitrogen mai ke kolamu kaomi haʻahaʻa ma hope o ka hoʻomaʻemaʻe hou ʻana. A alakaʻi ʻia ke kinoea argon mai ka waena o ke kolamu kaomi haʻahaʻa.
Gas extraction and storage: Oxygen, nitrogen and argon are reheated to gas and and then output. Some are liquefied for storage, such as liquid oxygen and liquid nitrogen. However, high purity oxygen (>99.5%), nitrogen (>99.9%), and argon (>Loaʻa ka 99.9%) ma ke noi.
Nā kānana molekole no ka hoʻokaʻawale ʻana i ka ea Cryogenic
13X APG Zeolite Molecular Sieve: Hoʻomohala kūikawā ia no ka ʻoihana hoʻokaʻawale ea cryogenic ea, pili i kekahi nui o nā mea hoʻokaʻawale ea cryo. 13X APG loaʻa iā X APG kahi mana adsorption koho ikaika no ka wai a me ka carbon dioxide.
13X HP Zeolite Molecular Sieve: Loaʻa iā ia ka oxygen kiʻekiʻe a me ka nitrogen separation performance a me ka lawa o ka oxygen production rate, ka mea i hoʻohana nui ʻia no ka oxygen generating units e hoʻokō ai i ka oxygen a me ka nitrogen separation, e hana ana i ka hoʻonui ʻana i ka oxygen a me ka olakino.
13X APG III Zeolite Molecular Sieve: He ʻano holomua o 13X APG. ʻO ka hana adsorption o zeolite 13X APG III he 60% ~ 70% kiʻekiʻe ma mua o ka 13X APG. ʻOiai ma nā kūlana kalapona haʻahaʻa haʻahaʻa, e hana maikaʻi ana ka mana adsorption o 13X APG III.
13X APG V Zeolite Molecular Sieve: Ua oi aku ka hana adsorption o 13X APG V ma mua o ka palua o ko 13X APG, a oi aku ma mua o 1.4 manawa o ko 13X APG III . 13X APG V molecular sieve he mea alaka'i ia ma ka oihana kaawale ea cryogenic, a ua oi loa aku na hoailona hana mamua o kona mau mua.
