Used primarily in drying gases and liquids, they effectively remove water molecules due to their precise 4Å pore size. In the petrochemical industry, they are essential for purifying natural gas and refining petroleum by separating impurities. They also play a crucial role in air separation processes for producing pure oxygen and nitrogen from air. In the packaging industry, they keep products moisture-free to extend shelf life. In the pharmaceutical industry, they remove water from solutions and products to ensure stability and longer shelf life. Additionally, they are utilized in laboratories for maintaining dry environments in sensitive experiments. In air conditioning and refrigeration systems, they help in dehumidifying air, enhancing efficiency and comfort. Their ability to selectively adsorb molecules makes them valuable in various industrial and scientific applications.
