Used primarily for drying gases and liquids, they effectively remove water and other small molecules from various substances. In the petrochemical industry, they are employed to purify natural gas and separate oxygen from air. They also play a crucial role in the dehydration of solvents and the removal of impurities in refining processes. Additionally, they are utilized in the packaging industry to maintain dry conditions and prevent moisture damage. Their selective adsorption properties make them valuable in laboratory settings for precise separation and purification tasks.
