When designing an adsorption dryer using heat regeneration, the determination of the loading capacity is quite complex, and has to undergo critical evaluation in order to arrive at reliable results. Deduced from the calculation example, Diagram 7.3.2.1 shows correction factors as a function of inlet temperature Ti and operating pressure po.
Diagram 7.3.2.1
The higher the temperature and the lower the operating pressure at the inlet to the equipment, the larger the adsorber must be, in order to be sure of achieving the desired drying capacity. The outlet temperature must not exceed the lower regeneration temperature range, otherwise the quality of compressed air drying through the entire period of adsorption becomes questionable.
