Molecular Sieve 4A DG

Molecular sieve HYG04DG is a synthetic zeolite of A-type crystal structure in potassium-sodium form a pore opening of 4 angstrom

HYG04DG(M.S.4A DG)

Description: Molecular sieve HYG04DG is a synthetic zeolite of A-type crystal structure in potassium-sodium form a pore opening of 4 angstroms (0.4nm)

Applications: Applied in deep dehydration of natural gas conbining high adsorption kinetics and physical stability which guarantees a longer lifespan. It is used to remove water, carbon dioxide, hydrogen sulfide and mercaptans with low molecular weight. If HYG04DG is applied in the situation of dealing with low content carbon dioxide, hydrogen sulfide(less then 200ppm) containing in the natural gas, pure natural gas can be pipeline-transported directly after adsorption.
