For example, saturated compressed air at a pressure of 100 PSIG and a temperature of 40℃ has a water content of 7.356g/M3 per cubic meter.
When the moisture in saturated compressed air under these conditions is adsorbed by the adsorbent, heat will be released, causing the ambient temperature at the moment of adsorption to rise by 23℃.
That is, adsorption temperature = (40 + 23)℃ = 63℃ ≈ desorption temperature 65℃.

At this time, even if moisture can be adsorbed by the adsorbent, because the bonding temperature difference is too small, once the kinetic energy factor generated by the flow rate of the compressed air is added, the water vapor will readily detach from the adsorbent and dissipate downstream.

The lower the inlet temperature, the better the adsorption effect. In design, it is generally recommended that the inlet temperature should not exceed 35℃.
