4A Molecular Sieve for drying natural gas
4A Molecular Sieve
Deep drying of gases and liquids such asair, Product namenatural gas, alkanes, andrefrigerants.
Static drying of pharmaceutical packaging.electronic components and perishable objectsPreparation and purification of argon.Used as a dehydrating agent in paints, fuelsand coatings
4A Molecular Sieve, is an alkali alumina silicate. It is the sodium form of the type A crystal structure. It has an effective pore opening of about 4 angstroms(0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
Application: Mainly used for drying natural gas and various chemical gases and liquids, refrigerants, pharmaceuticals, electronic materials and volatile substances, argon purification, methane, ethane, propane separation.
