Kupatukana kwa mpweya wa Cryogenic (kupatula kutentha kwa mpweya wochepa) ndi zida zodziwika bwino zopangira nayitrogeni (monga kupatukana kwa membrane ndi majenereta a nayitrogeni adsorption) ndi njira zazikulu zopangira nayitrogeni m'mafakitale. Ukadaulo wolekanitsa mpweya wa Cryogenic umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha luso lake lopanga nayitrogeni komanso chiyero chabwino kwambiri. Nkhaniyi ipenda bwino ubwino ndi kusiyana pakati pa kupatukana kwa mpweya wa cryogenic ndi zida zopangira nayitrogeni, ndikuwunika kofananira ndi chiyero cha nayitrogeni, kugwiritsa ntchito zida, komanso ndalama zoyendetsera ntchito, kuti apereke chidziwitso chosankha luso lopanga nayitrogeni yoyenera. Nayitrogeni woyera

Ubwino umodzi wofunikira pakulekanitsa kwa mpweya wa cryogenic pakupanga nayitrogeni ndikuti imatha kukhala yoyera kwambiri ya nayitrogeni. Kulekanitsa kwakuya kwa mpweya wa cryogenic kumatha kutulutsa nayitrogeni wokhala ndi chiyero chopitilira 99.999%, chomwe ndi chofunikira kwambiri pakugwiritsa ntchito komwe kumafunikira nayitrogeni yoyera kwambiri, monga kupanga zamagetsi, kaphatikizidwe ka mankhwala, ndi mafakitale apamlengalenga. Mosiyana, nembanemba kupatukana nayitrogeni kupanga zida angapereke nayitrogeni ndi chiyero cha 90% mpaka 99,5%, pamene kuthamanga swing adsorption (PSA) nayitrogeni kupanga zida angapereke nayitrogeni ndi chiyero mpaka 99,9%, komabe sangathe kufanana ntchito zakuya cryogenic mpweya kulekana. Choncho, kupatukana kwa mpweya wa cryogenic kumakhala kopikisana kwambiri m'mafakitale omwe amafunikira mpweya woyeretsa kwambiri.

Kuchuluka kwa nayitrogeni

Magawo akuya a cryogenic air olekanitsa amatha kupanga nayitrogeni wambiri, zomwe zimawapangitsa kukhala oyenera kwambiri pazochitika zomwe zimafunikira kwambiri nayitrogeni, monga mphero zachitsulo ndi zomera za mankhwala. Chifukwa kulekana kwa mpweya wa cryogenic kumapangitsa mpweya kutentha pang'ono ndikulekanitsa nayitrogeni ndi okosijeni, mphamvu yake yopanga gawo limodzi imatha kufikira mazana kapena masauzande a ma kiyubiki metres pa ola limodzi. Mosiyana ndi izi, zida zopangira nayitrogeni zolekanitsa nembanemba zili ndi mphamvu zochepa zopangira, zomwe zimakhala zoyenera kwa ogwiritsa ntchito m'mafakitale ang'onoang'ono ndi apakatikati omwe amafunikira nayitrogeni kuyambira makumi mpaka mazana a cubic metres pa ola limodzi. Chifukwa chake, pamikhalidwe yomwe ikufunika kwambiri nayitrogeni, kupatukana kwa mpweya waku cryogenic kumatha kukwaniritsa zosowa zamabizinesi.

Ndalama zoyendetsera ntchito

Kuchokera pakuwona kwa ndalama zogwirira ntchito, zida zakuya za cryogenic zolekanitsa mpweya zimakhala zotsika mtengo pantchito yayikulu yopitilira. Ndalama zoyamba za zida zolekanitsa mpweya za cryogenic ndizokwera, koma pakapita nthawi yayitali, mtengo wa gasi udzakhala wotsika kwambiri. Makamaka muzochitika zomwe zimafunikira kwambiri nayitrogeni ndi okosijeni nthawi imodzi, kupatukana kwa mpweya waku cryogenic kumatha kuchepetsa mtengo wonse wopangira gasi popangana. M'malo mwake, njira zopangira nayitrogeni zotulutsa nayitrogeni zimatengera mphamvu zambiri, makamaka popanga nayitrogeni wosayera kwambiri. Ndalama zogwirira ntchito ndizokwera kwambiri, ndipo kugwiritsa ntchito bwino kwachuma sikuli kokulirapo kuposa kulekanitsidwa kwa mpweya wa cryogenic pamene kuchuluka kwa nayitrogeni kuli kwakukulu. Zochitika zoyenera

Chigawo cholekanitsa mpweya wa cryogenic chimagwiritsidwa ntchito kwambiri m'mafakitale akuluakulu pomwe nayitrogeni ndi okosijeni zimafunikira, monga m'mafakitale achitsulo, mankhwala, ndi petrochemical. Kumbali inayi, zida zopangira nayitrogeni ndi zida zolekanitsa nembanemba ndizoyeneranso mabizinesi ang'onoang'ono ndi apakatikati, makamaka m'malo omwe nayitrogeni imayenera kupezeka mosavuta komanso mwachangu. Njira yolekanitsa mpweya wa cryogenic imafuna nthawi yokonzekera ndi kukhazikitsa, ndipo ndi yoyenera kwa malo akuluakulu okhala ndi ntchito yokhazikika kwa nthawi yayitali. Mosiyana ndi izi, zida zopatulira ma membrane ndi makina opangira ma swing adsorption ndizocheperako, zomwe zimapangitsa kuti zikhale zosavuta kuzisuntha ndikuziyika mwachangu, ndipo ndizoyenera mapulojekiti akanthawi kochepa kapena malo omwe masanjidwe osinthika amafunikira.

Mphamvu yopangira gasi

Ubwino winanso waukulu wa kupatukana kwa mpweya wa cryogenic ndi mphamvu yake yopanga mpweya. Kupatukana kwa mpweya wa Cryogenic sikumangotulutsa nayitrogeni koma kumatha kupanganso mpweya wina wamafakitale monga mpweya ndi argon, womwe umakhala ndi ntchito zofunika pakusungunula zitsulo, kupanga mankhwala, ndi zina. Chifukwa chake, ukadaulo wolekanitsa mpweya wa cryogenic ndi woyenera mabizinesi omwe ali ndi zofuna zosiyanasiyana zamagesi ndipo amatha kuchepetsa mtengo wonse wogula gasi. Mosiyana ndi izi, zida zolekanitsa ndi ma membrane nthawi zambiri zimatha kutulutsa nayitrogeni, ndipo kuyeretsedwa ndi kutulutsa kwa nayitrogeni wopangidwa kumatsatiridwa ndi zoletsa zambiri.

Kuteteza chilengedwe komanso kugwiritsa ntchito mphamvu

Makina olekanitsa mpweya wa Cryogenic alinso ndi maubwino ena pachitetezo cha chilengedwe komanso mphamvu zamagetsi. Popeza kupatukana kwa mpweya wa cryogenic kumagwiritsa ntchito njira yolekanitsa thupi ndipo sikufuna mankhwala, sikumayambitsa kuipitsa chilengedwe. Kuphatikiza apo, kudzera muukadaulo wowongolera komanso ukadaulo wobwezeretsa kutentha, mphamvu yogwiritsira ntchito mphamvu ya zida zolekanitsa mpweya wa cryogenic zasinthidwa kwambiri. Mosiyana ndi izi, zida zopangira nayitrogeni zimafunikira ma adsorption pafupipafupi komanso njira za desorption, zomwe zimapangitsa kuti pakhale mphamvu zambiri. Zida zopangira nayitrogeni zolekanitsa mamembrane, ngakhale zili ndi mphamvu zochepa zogwiritsa ntchito mphamvu, zimakhala ndi malire ogwiritsira ntchito, makamaka pakakhala chiyero chachikulu komanso zofunikira zoyenda kwambiri, kugwiritsa ntchito mphamvu zake sikuli bwino ngati zida zolekanitsa mpweya wa cryogenic.

Kusamalira ndi kugwira ntchito

Kusamalira machitidwe olekanitsa mpweya wa cryogenic ndizovuta kwambiri ndipo kumafuna akatswiri odziwa bwino ntchito yoyang'anira ndi kukonza nthawi zonse. Komabe, chifukwa cha magwiridwe ake okhazikika komanso moyo wautali wa zida, mayunitsi olekanitsa mpweya wa cryogenic amatha kugwira ntchito bwino pakanthawi yayitali. Mosiyana ndi izi, kukonzanso kwa zida zosiyanitsira nembanemba ndi kuthamangitsa zida zotsatsa ndizosavuta, koma zida zawo zazikulu, monga ma adsorbents ndi nembanemba, zimatha kuipitsidwa kapena kukalamba, zomwe zimapangitsa kuti pakhale kukonzanso kwakanthawi kochepa komanso kuwongolera kwakukulu, zomwe zingakhudze chuma chanthawi yayitali komanso kudalirika kwa zida.

Chidule

Pomaliza, ukadaulo wolekanitsa mpweya wozizira kwambiri uli ndi zabwino zambiri kuposa zida zopangira nayitrogeni zopatukana ndi nembanemba potengera kuyera kwa nayitrogeni, kuchuluka kwa kupanga, ndalama zogwirira ntchito, komanso kupanga nawo gasi. Kulekanitsa kwakuya kwa mpweya wozizira kumakhala koyenera makamaka kwa mabizinesi akulu akulu, makamaka m'malo omwe pali zofunika kwambiri pakuyera kwa nayitrogeni, kufunikira kwa okosijeni, komanso kuchuluka kwa kupanga. Kwa mabizinesi ang'onoang'ono ndi apakatikati kapena omwe amafunikira nayitrogeni wosinthika komanso kuchuluka kwachulukidwe kocheperako, zida zopangira nayitrogeni zosiyanitsidwa ndi membrane ndizothandiza kwambiri pazachuma. Chifukwa chake, mabizinesi ayenera kupanga zisankho zoyenera malinga ndi zosowa zawo zenizeni ndikusankha zida zoyenera zopangira nayitrogeni.

Ndife opanga ndi kutumiza kunja kwa gawo lolekanitsa mpweya. Ngati mukufuna kudziwa zambiri za ife:
