CNM 3A molecular sieve, suitable for drying gases and liquids and dehydrating hydrocarbons. It is widely used in deep drying of petroleum cracked gas; cracked gas generally contains a lot of water, which will form ice during cryogenic separation operations, and can cause blockage of pipelines and equipment with hydrocarbon hydrate crystals. Because petroleum cracked gas must undergo deep dehydration before cryogenic separation, the moisture content in the cracked gas is reduced. Since the 3A molecular sieve only adsorbs water in the cracked gas and does not adsorb larger hydrocarbon molecules, it can prevent olefin compounds from coking inside the molecular sieve pipeline, thereby extending the service life of the equipment.
