Beige Spheric 4a Molecular Sieve Desiccant For Drying Natural Gas Chemical

ISO Lvneng molecular sieve 4a zeolite mine drying natural gas chemical 2.0-3.0mm; 3.0-5.0mm; 4.0-6.0mm


overview


4a molecular sieve is a synthetic zeolite of A-type crystal structure in potassium-sodium form with a pore opening of 4 angstroms (0.4 nm). Adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, NH3, H2S, CO, methyl chloride, methyl bromide, methyl acetylene, ethane. Does not adsorb any molecular diameter greater than 4 angstroms (including propane). The more powerful selective adsorption capacity than any other molecular sieve. It is mainly applied in the drying gas, liquid. Widely used in drying oilfield associated gas and natural gas. Also widely used for the dehydration of ethanol.
