Application scope of water resistant silica gel for air separation

The water resistant silica gel of air separation unit is white spherical particles with high microporous structure, acid resistant (except hydrofluoric acid), alkali resistant and solvent resistant. Good thermal stability. Non toxic and odorless. It has high water resistance and adsorption. High compressive strength, long service life, low regeneration crushing rate is superior to other desiccants. Water resistant silica gel for air separation, also known as water resistant silica gel. Common silica gel has an open porous structure, a large specific surface area, and can adsorb a variety of substances. It is a good desiccant, adsorbent and catalyst carrier. However, it is easy to burst when encountering water, which reduces the particle integrity rate and affects the normal process. Good thermal stability. Non toxic and odorless. It has the advantages of high water resistance, adsorption, high compressive strength, long service life, low regeneration crushing rate, etc. Water resistant silica gel for air separation is mainly used for air drying in the air separation process, acetylene adsorption in the preparation of liquid air and liquid oxygen, drying of compressed air and various industrial gases, liquid adsorbent and catalyst carrier in petrochemical, electric power, brewing and other industries, and water purification in water treatment.

Water resistant silica gel (FNG) of air separation is used as adsorbent for carbon dioxide and acetylene in liquid air and liquid oxygen, desiccant for various gases, pre stage buffer desiccant for molecular sieve and silica gel protective bed, catalyst carrier and ion adsorbent in air separation.
