The regeneration effect deteriorates
Thread Content
How to deal with poor TSA regeneration performance? The regenerated gas comes from PSA.
The normal operation of this regeneration system is under program control. The main problems that typically occur are the failure of the adsorbent due to damaged heating elements, as well as steam heater leaks that lead to increased heater temperature. Either the adsorbent becomes ineffective due to poisoning, or it reaches the end of its service life. The most common issue is leakage from the switch valve (leakage at the valve ports); when conducting inspections, start by checking these aspects for reference.
Is it possible to enhance or reduce the regeneration effect by changing the temperature of the regenerated gas? How should the temperature be controlled in this case? The regenerating gas for bed heating and cooling on our side all passes through the regenerating gas heater.
Generally, adsorption materials have their inherent operating conditions, and when designing them, the adsorption time, regeneration time, and regeneration temperature must be determined based on these conditions; in some cases, cold blowing temperature, pressure equalization time, pressure release time, pressure charging time, and so on are also required. During use, it is essential to provide appropriate control parameters in accordance with the operating conditions. Moreover, the operating conditions cannot be changed; otherwise, the desired performance will not be achieved, the service life will be significantly reduced, or unnecessary energy consumption will occur. For reference.
