• Uses: Molecular sieves, 3A is used as desiccant in petroleum and chemical industries. It is useful for the drying of unsaturated hydrocarbons such as ethylene, propylene and butadiene. It is also used in the removal of water from ethanol. It finds application in the drying of certain chemicals namely ethanol, refrigerants and natural gas. It plays an important role as selective adsorption of water in insulated glass (IG) and polyurethane. It has been considered as a general-purpose drying agent in polar and non polar media. Molecular sieve 3A may be used in the following processes:As a general-purpose drying agent in polar and nonpolar media.Commercial dehydration of unsaturated hydrocarbon streams, including cracked gas, propylene, butadiene, acetyleneDrying polar liquids such as methanol and ethanol.Adsorption of molecules such as NH3 and H2O from a N2/H2 flow.
