molecular sieve adsorption
LPG Dehydration Used 4A Molecular Sieve Adsorbent 2.0-3.0mm, 3.0-5.0mm,4.0-6.0mm
4A molecular sieve has the 4Å aperture, it can absorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, don’t absorb any molecules(including propane) whose aperture more than 4Å.4A molecular sieve has the higher performance of water adsorption capability than any other molecular sieve. It is one of molecular sieves varieties which has the largest dosage.
