Used primarily for drying gases and liquids, especially in the petrochemical industry, to remove water and other small molecules. They are effective in purifying natural gas by adsorbing moisture and impurities, ensuring the gas meets pipeline specifications. In laboratories, they are employed to maintain anhydrous conditions in sensitive reactions. They also play a crucial role in the packaging industry to prevent moisture damage in pharmaceuticals, electronics, and food products. Additionally, they are utilized in air brake systems for trucks and trains to adsorb water and prevent freezing in cold weather.
