3A Molecular Sieve
3A Molecular Sieve
Mainly used in the drying of unsaturatedhydrocarbons such as ethylene, propylene,butadiene, etc. of petroleum cracking gasDrying of polar liquids such as methanoland ethanol.W Air drying. Drying of natural gas and methane gas
Quick Details
3A Molecular Sieve, is an alkali metal alumina silicate. It is the potassium form of the type A crystal structure.It has an effective pore opening of about 3 angstroms(0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers.
According to the application of industrial characteristics, we produce molecular sieve has faster adsorption speed, more number of regeneration, high crushing strength and ability to resist pollution, improve the utilization efficiency of the molecular sieve and prolong the service life of molecular sieve, dry gas liquid phase depth is petroleum, chemical industry, refining, necessary choice of desiccant polymerization.
