molecular sieve

Molecular sieve 3A is a kind of alkali aluminosilicate, able to adsorb molecules with their critical diameters no more than 3A. In water adsorption process, it can adsorb water while exclude other hydrocarbon molecules, so it is widely used in deep drying of oil cracked gases, e. g., ethylene, propylene, butadiene, acetylene and natural gas, etc. Molecular sieve 3A is also used in the drying of polar liquids (e. g., ethanol, LPG and solvents, etc. Molecular sieve 3A produced by PangTai has successfully substituted for 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 less than1ppm (dew point : minus 70 centigrade).
