What is water resistant silica gel for air separation

What is water resistant silica gel for air separation



The appearance of water resistant silica gel (FNG) 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, adsorption and compressive strength. The utility model has the advantages of long service life, low regeneration crushing rate, etc. Water resistant silica gel (FNG) 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 treatment


Product use:


Water resistant silica gel (FNG) of air separation is used in air separation as adsorbent for carbon dioxide and acetonitrile 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.


1. Fine pore air separation silica gel (original FNG-I)


The main feature of this product is that it has a strong adsorption capacity for water under the condition of low relative humidity, so as to play the role of dehumidification and drying. The selective adsorption of some harmful substances in the medium can also achieve the goal of purification.


2. Coarse pore air separation silica gel FNG2)


This product is compatible with coarse pore silica gel and fine pore silica gel. It is the best desiccant and purifying agent no matter under low relative humidity or high humidity.


3. Air separation silica gel (FNG3)

Under saturation, the water absorption capacity of this product is generally more than twice that of Type A silica gel. Therefore, in application, in order to achieve the purpose of drying and purification, it is generally used together with microporous silica gel and molecular sieve. This product has an ideal and stable pore structure and is widely used as catalyst carrier.
