Sureway Chemical Engineering Technology Limited

Technical introduction

Use air as raw material, through filtration, pre-cooling, molecular sieve absorption etc. purification process to remove the dust, water, carbon dioxide, hydrocarbons etc. impurities, and use compression and expansion technology to liquefy of cleaned air, then use cryogenic ratification technology to separation the liquid air, and get oxygen/liquid oxygen, nitrogen/liquid nitrogen, liquid argon products
