How to deal with leakage in pressure swing adsorbents? Leakage of the adsorbent from the bottom can only be caused by a problem with the mesh: 1. The mesh was not pressed properly during installation, resulting in gaps. 2. When installing the adsorbent, the screen was not checked, and it was damaged. 3. The mesh size of the screen selected should be large enough, at least 20 mesh or more. 4. The strength of the screen is insufficient. China Pressure Swing Adsorption Network: 5. If there are problems with the sieve bed, and conditions permit, remove the adsorbent to repair the sieve bed and reinstall it afterward. If that’s not possible, strengthen the filter at the bottom cover of the adsorption cylinder, which will allow for short-term operation. 6. The perimeter of the sieve mesh is not properly compressed, resulting in uneven pressure; this causes alternating positive and negative pressures in certain areas during operation, leading to leakage of the adsorbent. If it is not reinstalled properly, the bed layer becomes increasingly loose, and the molecular sieve remains in a suspended state, leading to rapid wear and ultimately rendering all the adsorbent useless.
