1. Kudzvanywa kwemhepo uye kucheneswa kwayo

Mhepo inopinda mu air compressor mushure mekubvisa guruva netsvina yemuchina kuburikidza ne air filter, yodzvanywa kusvika pakumanikidzwa kunodiwa, yozotumirwa ku air cooler kuderedza tembiricha yemhepo. Wobva wapinda mu air drying purifier kuti ubvise hunyoro, carbon dioxide, acetylene nezvimwe zvinhu zvinosvibisa mumhepo.

2. Kupatsanurwa kwemhepo

Mhepo yakachena inopinda muchinhu chinochinja kupisa chiri mushongwe yekuparadzanisa mhepo, inotonhodzwa kusvika pakupisa kwakazara negasi re reflux (nitrogen yechigadzirwa, gasi rakasviba), uye inotumirwa pasi peshongwe yekururamisa, uko nitrogen inowanikwa pamusoro peshongwe, uye mweya wemvura unodhonzwa wozotumirwa pasi peshongwe yekururamisa. Pinda mu evaporator yekudziya kuti ipwe, uye panguva imwe chete chikamu chenitrogen chinotumirwa kubva mushongwe yekururamisa, chikamu chenitrogen yemvura yakadhonzwa chinoshandiswa semvura ye reflux yeshongwe yekururamisa, uye chimwe chikamu chinoburitswa kubva mushongwe yekuparadzanisa mhepo sechigadzirwa chenitrogen yemvura.

Gasi rinobuda mumhepo rinodziisa kubva mumhepo inodziya inodziiswazve kusvika pa130K nechinhu chikuru chinochinja-chinja kupisa uye rinopinda muexpander kuti riwedzere kutonhora kuti ripe simba rekutonhodza shongwe yekuparadzanisa mhepo. Chikamu chegasi rinowedzerwa chinoshandiswa pakugadzirisa nekutonhodza molecular sefa, uye rozoburitswa mumhepo inotonhorera.

3. Kupisa nitrogen yemvura

Nitrogen yemvura inobva mudenga rekuparadzanisa mhepo inochengetwa mutangi rekuchengetera nitrogen yemvura. Kana michina yekuparadzanisa mhepo yagadziriswazve, nitrogen yemvura iri mutangi rekuchengetera inopinda muvaporizer yodziiswa, yozotumirwa kupombi yenitrogen yechigadzirwa.

Kugadzirwa kwenitrogen ine cryogenic kunogona kugadzira nitrogen ine kuchena kwe ≧ 99.999%.
