Medium variable gas temperature issue
Thread Content
Why shouldn’t the intermediate temperature in PSA be too high? What are the consequences of having a high temperature?
Medium transformation is also a reaction, right? High temperatures are not good for the catalyst, are they?
The temperature level has an impact on the adsorption efficiency of PSA adsorbents; too high or too low a temperature reduces the adsorption efficiency, leading to lower hydrogen purity or yield. It is generally advisable to maintain the temperature between 30 and 40°C
It is easy to absorb at low temperatures and high pressures; however, too high a temperature can lead to the presence of water.
High temperature with high water content; PSA cannot resolve it
High temperatures present two problems: first, it increases the entrapped moisture, affecting the lifespan of the adsorbent； Secondly, an increase in the gas temperature entering the PSA bed reduces the adsorption capacity and lowers the purity of hydrogen.

The main issue is still the water; the temperature cannot be too high. What is the typical inlet temperature control for the reactive reactor among you?
A high intake air temperature makes it easy for moisture to be carried in, which is easy to understand. There is also the working principle of PSA: adsorption at high pressure, desorption at low pressure, adsorption at low temperature, and desorption at high temperature.
