4A molecular sieve
Details
Introduction: 4A molecular sieve is a sodium aluminosilicate crystal aperture 4Å (0.4nm), can be adsorbed on the critical diameter is not greater than the molecule itself aperture.
Scope of application:
gas and liquid drying can adsorption H20, H2S, NH3, SO2, CO2,, C2H5OH, C2H6, etc.;
oil field associated gas, dry gas;
some of the gas or liquid, refined or purified, such as argon purification.
