How do you determine the purge flow rate required for regeneration in a heatless regenerative dehumidifying equipment?

Assuming that purge air flows through the regenerating tower at the same temperature and flow rate as it flows through the drying tower, moisture adsorbed by the desiccant will be discharged into the atmosphere along with the purge air during regeneration. Since the regenerating tower is almost at atmospheric pressure, the required purge flow rate is, in principle, one divided by the value of the on-line pressure.

 

In reality, however, flow rates and temperatures fluctuate, and there are other factors as well to consider. The purge flow rate actually required should be a little higher than: {1 / (operating pressure + atmospheric pressure)}.
