Application

1: Absorb moisture from natural gas to prevent pipeline freezing and blockage, ensuring the safety and purity of storage and transportation.

2: Remove moisture impurities from gases such as ethylene and propylene, meeting the drying requirements for subsequent polymerization reactions.

3: Absorbs moisture in the cavity to prevent the glass from fogging or condensation, prolonging its service life and maintaining its light transmittance.

4: Selective adsorption of ethanol moisture, facilitating the preparation of high-purity anhydrous ethanol, meeting the needs of multiple industries.
