The layout of externally regenerated adsorption dryers, filled with silica gel, serves as an example also for other adsorbers using heat regeneration. The simplified layout for compressed air is explained and the logical structure of the calculation, including heat allowance, are shown. All numerical values and diagrams apply, as long as extreme limiting values are not exceeded. To form a basis for the design, the following data must be pre-determined : Volume flow referred to 1 bar absolute Voperating pressure poinlet temperature T¡pressure dewpoint Pdploading or charging time tLFurther values or materials data for the adsorber layout can be obtained from the applicable diagrams or tables in each case. Indications are provided in places where this applies.
