Cryogenic mhepo kupatsanurwa (yakaderera-kupisa kwemhepo kupatsanurwa) uye yakajairika nitrogen kugadzira michina (senge membrane kupatsanurwa uye pressure swing adsorption nitrogen jenareta) ndiyo nzira huru dzekugadzira nitrogen yemaindasitiri. Cryogenic air separation tekinoroji inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekuita kwayo nitrogen kugadzira kugona uye kuchena kwakanyanya. Ichi chinyorwa chichanyatso ongorora zvakanakira uye mutsauko pakati pe cryogenic mhepo yekuparadzaniswa uye nitrogen zvigadzirwa zvekugadzira, kuita ongororo yekuenzanisa maererano nekuchena kwenitrogen, kushandiswa kwemidziyo, uye mutengo wekushandisa, kuitira kupa chirevo chekusarudza yakakodzera nitrogen kugadzira tekinoroji. Nitrogen kuchena

Imwe yakakosha mukana weyakadzika cryogenic mhepo kuparadzaniswa kwekugadzirwa kwenitrogen ndeyekuti inogona kuwana yakanyanya kuchena nitrogen. Yakadzika cryogenic mhepo kupatsanurwa inogona kazhinji kuburitsa nitrogen nekuchena kweinopfuura 99.999%, iyo yakakosha kune maapplication anoda yakanyanya kuchena nitrogen, sekugadzira zvemagetsi, makemikari synthesis, uye maindasitiri emuchadenga. Kusiyana neizvi, membrane kupatsanurwa nitrogen kugadzira michina inogona kungopa nitrogen nekuchena kwe90% kusvika 99.5%, nepo pressure swing adsorption (PSA) nitrogen kugadzira michina inogona kupa nitrogen nekuchena kwekusvika 99,9%, asi zvakadaro haigone kuenderana nekuita kweyakadzika cryogenic kupatsanurwa kwemhepo. Nokudaro, kuparadzaniswa kwemhepo yakadzika cryogenic kunowedzera kukwikwidzana mumaindasitiri anoda magasi makuru-kuchena.

Nitrogen kugadzirwa kwehuwandu

Deep cryogenic air separation units inokwanisa kuburitsa huwandu hukuru hwenitrogen, zvichiita kuti dzinyatsokodzera zviitiko zvine kudiwa kwakawanda kwenitrogen, senge simbi mill nemiti yemakemikari. Nekuti yakadzika cryogenic mhepo kupatsanurwa inonyungudutsa mhepo pakudziya kwakaderera uye yobva yapatsanura nitrogen neokisijeni, iyo imwechete-yuniti yekugadzira kugona kwayo inogona kusvika mazana kana kunyange zviuru zvecubic metres paawa. Kusiyana neizvi, membrane kupatsanurwa uye kudzvanywa swing adsorption nitrogen yekugadzira michina ine mashoma ekugadzira, anowanzo akakodzera kune vadiki uye epakati-saizi vashandisi veindasitiri vane nitrogen inoda kubva pamakumi kusvika kumazana emacubic metres paawa. Naizvozvo, mumamiriro ezvinhu ane yakakwira nitrogen kudiwa, yakadzika cryogenic mhepo kupatsanurwa kunogona kuita zvirinani zvinodiwa nemabhizinesi.

Operating cost

Kubva pakuona kwemitengo yekushanda, yakadzika cryogenic mhepo yekuparadzanisa michina inowedzera mari kune yakakura-inoenderera mberi kushanda. Kudyara kwekutanga kweyakadzika cryogenic mhepo yekuparadzanisa michina yakakwira, asi panguva yekushanda kwenguva refu, iyo unit gasi mutengo uchave wakaderera. Kunyanya mumamiriro ezvinhu ane kudiwa kwakanyanya kwenitrogen neokisijeni panguva imwe chete, yakadzika cryogenic kupatsanurwa kwemhepo kunogona kuderedza zvakanyanya mutengo wese wekugadzira gasi kuburikidza nekubatana-kugadzira. Zvakapesana, kudzvanya swing adsorption nitrogen kugadzirwa uye membrane kupatsanura matekinoroji ane yakanyanya kushandiswa kwesimba, kunyanya kana ichigadzira yakakwira-kuchena nitrogen. Mari yekushanda yakawedzera, uye kushanda kwehupfumi kwehupfumi hakuna kukwira seyakadzika cryogenic air kupatsanurwa kana huwandu hwekugadzira nitrogen yakakura. Mamiriro ezvinhu anoshanda

Iyo cryogenic air separation unit inoshandiswa zvakanyanya mukugadzirwa kwakakura kwemaindasitiri uko zvese nitrogen neokisijeni zvinodiwa, senge mumaindasitiri esimbi, makemikari, uye petrochemical. Kune rimwe divi, kumanikidza swing adsorption nitrogen kugadzira michina uye membrane yekuparadzanisa michina inonyanya kukodzera kumabhizinesi madiki uye epakati, kunyanya mumamiriro ezvinhu apo nitrogen inoda kuwanikwa zviri nyore uye nekukurumidza. Iyo cryogenic air separation system inoda imwe pre-kuronga uye yekuisa nguva, uye yakakodzera kune yakakura-yakakura zvivako nekushanda kwenguva refu yakagadzikana. Kusiyana neizvi, membrane kupatsanurwa uye kudzvanywa swing adsorption michina idiki muhukuru, zvichiita kuti zvive nyore kufambisa nekumisikidza nekukurumidza, uye inokodzera mapurojekiti enguva pfupi kana nzvimbo dzinodikanwa marongerwo anochinjika.

Gasi rekugadzira simba

Imwe mukana mukuru wekuparadzaniswa kwemhepo ye cryogenic ndeye kugona kwayo kugadzira gasi. Cryogenic air separation haingobudisi nitrogen chete asi inogonawo kugadzira mamwe magasi emumaindasitiri akadai seokisijeni neargon, ane maapplication akakosha mukunyungudutsa simbi, kugadzirwa kwemakemikari nezvimwe. Naizvozvo, cryogenic mhepo yekuparadzanisa tekinoroji yakakodzera kumabhizinesi ane akasiyana gasi zvinoda uye inogona kuderedza zvakanyanya mutengo wekutenga gasi. Nekusiyana, kudzvanya swing adsorption uye membrane yekuparadzanisa michina kazhinji inogona chete kuburitsa nitrogen, uye kuchena uye kubuda kweiyo nitrogen inogadzirwa zvinoenderana nekurambidzwa kwakawanda.

Kuchengetedza kwezvakatipoteredza uye kushanda nesimba

Cryogenic air separation systems inewo zvimwe zvakanakira maererano nekuchengetedzwa kwezvakatipoteredza uye kushanda nesimba. Sezvo kupatsanurwa kwemhepo ye cryogenic kunoshandisa nzira yekuparadzanisa kwemuviri uye haidi makemikari emakemikari, haakonzeri kusvibiswa kwezvakatipoteredza. Uye zvakare, kuburikidza neyakagadziridzwa dhizaini uye tekinoroji yekudzoreredza tekinoroji, iyo simba rekushandisa simba reiyo cryogenic mhepo yekuparadzanisa michina yakagadziridzwa zvakanyanya. Mukupesana, kudzvanya swing adsorption nitrogen kugadzira michina inoda kazhinji adsorption uye desorption maitiro, zvichikonzera kushandiswa kwakanyanya kwesimba. Membrane kupatsanurwa nitrogen midziyo yekugadzira, kunyangwe iine simba shoma shoma, ine mashoma ekushandisa scope, kunyanya muzviitiko zvekuchena kwakanyanya uye kuyerera kukuru kwezvinodiwa, simba rayo rekushandisa hakuna kunaka seye cryogenic mhepo yekuparadzanisa michina.

Maintenance uye kushanda

Kugadziriswa kwe cryogenic air separation systems kwakaoma uye kunoda nyanzvi dzine ruzivo rwehutungamiri nekugadzirisa nguva dzose. Zvisinei, nekuda kwekushanda kwayo kwakagadzikana uye hupenyu hurefu hwemichina, cryogenic air separation units inogona kuchengetedza kushanda kwakanaka mukushanda kwenguva refu. Kusiyana neizvi, kuchengetedzwa kwe membrane kupatsanurwa uye kudzvanywa swing adsorption zvishandiso zviri nyore, asi izvo zvakakosha zvikamu, senge adsorbents uye membrane zvikamu, zvinotapukira kusvibiswa kana kuchembera, zvichikonzera kupfupika kwekugadzirisa uye yakakwirira gadziriso frequency, izvo zvinogona kukanganisa hupfumi hwenguva refu uye kuvimbika kwemidziyo.

Summary

Mukupedzisa, tekinoroji yakadzika inotonhorera yekuparadzanisa tekinoroji ine zvakakosha pamusoro peyakajairwa kudzvanya swing adsorption uye membrane kupatsanurwa nitrogen kugadzira michina maererano nenitrogen kuchena, vhoriyamu yekugadzira, mutengo wekushandisa, uye gasi co-kugadzira. Kupatsanura kwakadzika kutonhora kwemhepo kunonyanya kukodzera mabhizinesi makuru emaindasitiri, kunyanya mumamiriro ezvinhu uko kune zvakanyanya kudikanwa kwekuchena kwenitrogen, kudiwa kweokisijeni, uye huwandu hwekugadzira. Kune mabhizinesi madiki uye epakati-saizi kana ayo ane inochinjika nitrogen kudiwa uye yakaderera mavhoriyamu ekugadzira, kudzvanya swing adsorption uye membrane kupatsanurwa nitrogen michina yekugadzira ndiyo inogonesa hupfumi sarudzo. Naizvozvo, mabhizinesi anofanirwa kuita sarudzo dzine musoro zvichibva pane zvavanoda chaizvo uye sarudza yakanyatsokodzera nitrogen kugadzira michina.

Isu tiri mugadziri uye mutengesi wemhepo yekuparadzanisa unit. Kana uchida kuziva zvakawanda nezvedu:
