4A-DG Molecular Sieve

Na12[(AlO2)12(SiO2)12].XH2O

4A-DG molecular sieve is mainly suitable for deep dehydration dry of natural gas, high strength of which can fully guarantee its service life. Also, it can absorb moisture in natural gas, a small amount of carbon dioxide, hydrogen sulfide and other trace impurities. Especially natural gas with low content of carbon dioxide and hydrogen sulfide of less than 200 ppm should be gone through adsorption treatment by our DG molecular sieve and then be directly piped.
