Kupatsanurana kwemhepo inotsvedza (kupatsanurana kwemhepo inodziya zvishoma) uye michina inogadzira nitrogen (yakadai sekupatsanurana kwemembrane uye majenareta enitrogen anotsvedza nepressure swing) ndiyo nzira huru dzekugadzira nitrogen mumaindasitiri. Tekinoroji yekupatsanurana kwemhepo inotsvedza inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekugona kwayo kugadzira nitrogen zvakanaka uye kuchena kwakanaka. Chinyorwa chino chichaongorora zvakanakira nekusiyana pakati pekupatsanurana kwemhepo inotsvedza nemidziyo yekugadzira nitrogen, tichiita ongororo yekuenzanisa maererano nekuchena kwenitrogen, kushandiswa kwemidziyo, uye mari yekushandisa, kuitira kupa referensi yekusarudza tekinoroji yakakodzera yekugadzira nitrogen. Kuchena kwenitrogen

Imwe mukana mukuru wekupatsanurwa kwemhepo ine cryogenic yakadzika pakugadzira nitrogen ndeyekuti inogona kuwana nitrogen yakachena zvakanyanya. Kupatsanurwa kwemhepo ine cryogenic yakadzika kunogona kugadzira nitrogen ine kuchena kweinopfuura 99.999%, izvo zvakakosha kumashandisirwo anoda nitrogen yakachena kwazvo, senge kugadzira zvemagetsi, kugadzira makemikari, uye maindasitiri emuchadenga. Kusiyana neizvi, michina yekugadzira nitrogen ine membrane separation inogona kungopa nitrogen kuchena kwe90% kusvika 99.5%, nepo michina yekugadzira nitrogen ine pressure swing adsorption (PSA) inogona kupa nitrogen kuchena kweinosvika 99.9%, asi haigone kuenzana nekushanda kwe deep cryogenic air separation. Saka, deep cryogenic air separation inonyanya kukwikwidzana mumaindasitiri anoda magasi ane kuchena kwakanyanya.

Huwandu hwekugadzirwa kwenitrogen

Mayuniti ekuparadzanisa mweya ane cryogenic deep cryogenic ane kugona kugadzira nitrogen yakawanda, zvichiita kuti ive yakakodzera mamiriro ezvinhu ane nitrogen yakawanda, akadai semagayo esimbi nemafekitori emakemikari. Nekuti kupatsanurwa kwemhepo ine cryogenic deep cryogenic kunonyungudutsa mhepo patembiricha yakaderera uye wozoparadzanisa nitrogen neokisijeni, kugona kwayo kugadzira imwe chete kunogona kusvika mazana kana kunyange zviuru zvema cubic metres paawa. Kusiyana neizvi, michina yekugadzira nitrogen ine membrane separation uye pressure swing adsorption ine kugona kushoma kwekugadzira, kazhinji yakakodzera vashandisi vemaindasitiri madiki nepakati vane nitrogen inoda kubva pamakumi kusvika kumazana ema cubic metres paawa. Naizvozvo, mumamiriro ezvinhu ane nitrogen yakawanda, kupatsanurwa kwemhepo ine cryogenic deep cryogenic kunogona kusangana zviri nani nezvinodiwa nemabhizinesi.

Mari yekushandisa

Kubva pamaonero emari yekushandisa, michina yekuparadzanisa mweya inodzika midzi inodhura zvakanyanya pakushanda kukuru kunoenderera mberi. Mari yekutanga yekushandisa michina yekuparadzanisa mweya inodzika midzi yakakwira, asi panguva yekushanda kwenguva refu, mutengo wegesi weyuniti uchava wakaderera. Kunyanya mune zviitiko zvine kudiwa kukuru kwenitrogen neokisijeni panguva imwe chete, kuparadzanisa mweya inodzika midzi kunogona kuderedza zvakanyanya mutengo wekugadzirwa kwegesi kuburikidza nekugadzira pamwe chete. Kusiyana neizvi, kugadzirwa kwenitrogen inokatyamadzwa ne pressure swing uye matekinoroji ekuparadzanisa membrane anoshandisa simba rakawanda, kunyanya pakugadzira nitrogen ine purity yakawanda. Mari yekushandisa yakakwira, uye kushanda zvakanaka kwehupfumi hwekushanda hakuna kukwira sekuparadzanisa mweya inodzika midzi kana huwandu hwekugadzira nitrogen hwakawanda. Mamiriro ezvinhu anoshanda

Chigadziko chemhepo chinoparadzanisa mhepo chinoshandiswa zvakanyanya mumaindasitiri makuru uko kunodiwa nitrogen neokisijeni, senge mumaindasitiri esimbi, makemikari, uye petrochemical. Kune rumwe rutivi, michina yekugadzira nitrogen inosundwa nepressure swing uye michina yekuparadzanisa membrane yakakodzera mabhizinesi madiki nepakati, kunyanya mumamiriro ezvinhu apo nitrogen inoda kuwanikwa nenzira inochinjika uye nekukurumidza. Sisitimu yekuparadzanisa mhepo inosumbwa necryogenic inoda nguva yakatarwa yekuronga uye yekuisa, uye yakakodzera nzvimbo hombe dzine kushanda kwakasimba kwenguva refu. Kusiyana neizvi, michina yekuparadzanisa membrane uye yekusundwa nepressure swing idiki, zvichiita kuti zvive nyore kuifambisa nekuiisa nekukurumidza, uye yakakodzera mapurojekiti enguva pfupi kana nzvimbo dzinodiwa kurongeka kunochinjika.

Kukwanisa kugadzira gasi

Imwe mukana mukuru wekuparadzanisa mhepo ine cryogenic ndiko kugona kwayo kugadzira gasi. Kuparadzanisa mhepo ine cryogenic hakungoburitsi nitrogen chete asiwo kunogona kugadzira mamwe magasi eindasitiri akadai seokisijeni neargon, ayo ane mashandisirwo akakosha mukunyungudutsa simbi, kugadzira makemikari, nedzimwe nzvimbo. Saka, tekinoroji yekuparadzanisa mhepo ine cryogenic yakakodzera kumabhizinesi ane magasi akasiyana siyana uye inogona kuderedza zvakanyanya mutengo wekutenga gasi. Kusiyana neizvi, michina yekudzvanya inodzungudza pressure swing uye yekuparadzanisa membrane inowanzo gadzira nitrogen chete, uye kuchena uye kubuda kwenitrogen inogadzirwa kunoenderana nezvirambidzo zvakawanda.

Kudzivirirwa kwezvakatipoteredza uye kushandiswa zvakanaka kwesimba

Masisitimu ekuparadzanisa mhepo ane zvakanakirawo maererano nekuchengetedzwa kwezvakatipoteredza uye kushanda zvakanaka kwesimba. Sezvo kupatsanura mhepo ine cryogenic kuchishandisa nzira yekuparadzanisa panyama uye kusingade mishonga yemakemikari, hakukonzeri kusvibiswa kwezvakatipoteredza. Pamusoro pezvo, kuburikidza nekugadzirwa kwakagadziridzwa uye tekinoroji yekudzoreredza kupisa, kushanda zvakanaka kwemidziyo yekuparadzanisa mhepo ine cryogenic kwakavandudzika zvakanyanya. Kusiyana neizvi, michina yekugadzira nitrogen inodzungudza kumanikidzwa inoda maitiro ekuwedzera uye kubvisa mvura, zvichikonzera kushandiswa kwakanyanya kwesimba. Midziyo yekugadzira nitrogen inodzungudza membrane, kunyangwe iine simba shoma, ine mukana mudiki wekushandisa, kunyanya kana paine kuchena kwakanyanya uye zvinodiwa pakuyerera kukuru, kushanda kwayo nesimba hakuna kunaka semidziyo yekuparadzanisa mhepo ine cryogenic.

Kugadzirisa uye kushanda

Kugadziriswa kwemaitiro ekuparadzanisa mhepo ane cryogenic kwakaoma uye kunoda mainjiniya vane ruzivo rwekutarisira nekugadzirisa nguva dzose. Zvisinei, nekuda kwekushanda kwayo kwakasimba uye hupenyu hwemidziyo hurefu, mayuniti ekuparadzanisa mhepo ane cryogenic anogona kuchengetedza kushanda zvakanaka mukushanda kwenguva refu. Kusiyana neizvi, kuchengetedza michina yekuparadzanisa membrane uye pressure swing adsorption kuri nyore, asi zvikamu zvavo zvikuru, zvakaita seadsorbents ne membrane components, zvinogona kusvibiswa kana kukwegura, zvichikonzera kupfupika kwekugadzirisa uye frequency yekuchengetedza yakakwira, izvo zvinogona kukanganisa hupfumi hwenguva refu uye kuvimbika kwemidziyo.

Pfupiso

Mukupedzisa, tekinoroji yekuparadzanisa mhepo inotonhorera yakadzika ine zvakanakira zvikuru pamusoro pemidziyo yekugadzira nitrogen inodzvinyirirwa nemhepo uye membrane separation maererano nekuchena kwenitrogen, huwandu hwekugadzira, mari yekushandisa, uye gasi pamwe chete. Kuparadzanisa mhepo inotonhorera yakadzika kwakakodzera zvikuru kumabhizinesi makuru emaindasitiri, kunyanya mumamiriro ezvinhu apo pane zvinodiwa zvakanyanya zvekuchena kwenitrogen, kudiwa kweokisijeni, uye huwandu hwekugadzira. Kune mabhizinesi madiki nepakati kana ayo ane nitrogen inochinjika uye huwandu hwekugadzira hwakaderera, pressure swing adsorption uye membrane separation michina yekugadzira nitrogen ndiyo sarudzo dzinoshanda zvakanyanya. Naizvozvo, mabhizinesi anofanira kuita sarudzo dzakakodzera zvichienderana nezvaanoda chaizvo uye kusarudza michina yakakodzera yekugadzira nitrogen.

Isu tiri vagadziri uye vanotumira kunze kwenyika vechikamu chekuparadzanisa mhepo. Kana muchida kuziva zvakawanda nezvedu:
