Used primarily in gas and liquid drying processes, they effectively remove water and other small molecules from various substances. They are widely applied in the petrochemical industry to purify and separate hydrocarbons, ensuring the quality of fuels and chemicals. In natural gas processing, they help remove carbon dioxide and hydrogen sulfide, enhancing the purity of the gas. They are also utilized in the insulation industry to maintain the efficiency of double-pane windows by adsorbing moisture. Additionally, they play a crucial role in the production of oxygen concentrators, where they separate nitrogen from air to deliver high-purity oxygen for medical use. Their ability to selectively adsorb molecules makes them valuable in refrigeration systems to remove impurities and maintain system performance. Specifically, 5Å molecular sieves in 80-100 mesh size are dedicated for use as packing material in gas and liquid chromatography columns, enabling precise molecular separations in laboratory applications.
