The following calculation scheme for adsorption dryers with heatless regeneration is based on commercially available desiccant. This section deals with the layout design for compressed air. T he diagrams presented are not valid for extreme values. The following data, valid at the adsorber inlet point have, in principle, to be indicated for minimum and maximum loading range as a basis for the design :
| Volume flow referred to 1 bar | V | (m3/hr)
| t = time (mins) |
| operating pressure | po | (bar abs) | |
| Inlet temperature | T¡ | (°C) | |
| Pressure dewpoint | Pdp | (°C) | |
This data will be required for the individual steps in the calculation and are usually based on
- estimated experience values
- data measured at the installation
In practice, many people operate almost exclusively with experience values. However, only measured values form an accurate basis for dryer design. The calculation is worked out for a specified adsorption time ta. Adsorber layout design takes place in individual steps on the basis of physical laws.
