Abstract— Gases used in industry must meet the required parameters such as the content of gas impurities, moisture content and mechanical impurities, which have a significant impact on its subsequent use. Various industrial drying methods are used to remove moisture. Among the most used drying methods are methods based on subcooling the gas below the condensation temperature, adsorption drying methods or special methods. The article primarily deals with the drying of gases in a fluid layer of ground silica gel. It describes the issue of the suitability of silica gel as an adsorbent in any form of its structure, the advantages and disadvantages of its use.
