Application fields of cryogenic air separation equipment

The raw gas for variable pressure adsorption contains H2S, which needs to be removed if it is greater than 20 ppm, taking into account the life of the adsorbent and the quality of the product. the removal of H2S can be done by a dry desulphurisation process using a fixed bed with a room temperature iron oxide desulphurising agent inside. Desulphurisation towers can usually be set up as two or more,...

Small air separation unit is the unit that separates air into oxygen and other gases by first compressing and cooling the air into a liquid state and then using the characteristic that oxygen has a different boiling point to other gases in the air to obtain oxygen and liquid oxygen by evaporation and separation, as well as other rare gases as required.Liquid oxygen is produced using the cryogenic separation of air. The basic principle is to u...
