3A Molecular Sieve is a kind of alkali aluminosilicate,able to adsorb molecules with their critical diameters no more than water adsorption process,it can adsorb water while exclude other hydrocarbon moleculars,so it is widely used in deep drying of oil cracked gas,e.g.ehylene,propylene,butadience,acetylene and natural gas.3A molecular sieve is also used in the drying of polar liquids (e.g.ethanol),LPG and solvents,etc.The 3A molecular sieve produced by our company has sucessfully the imported products in petrochemical and oil industries,for example,it can be used as the dehydrator of oil cracked gas.after it is adsorbed by 3A,the gaseous water in it is <1ppm(dew point <~70℃).
