Field: Chemical engineering (Chemistry)
Classification: CPC B | IPC B

Claim 1:
2. The method according to claim 1 wherein for Cop the following formula is used:

CΔP=√{square root over (ΔPref/ΔPgem)};

where ΔPref is the reference pressure drop (ΔPref) over the drying device and ΔPgem is the average pressure drop (ΔPgem) over the drying device measured over a drying cycle or CAP is determined or measured using the measured or determined flow rate, wherein:

Cflow=Flow rateref/Flow rategem;

where Flow rateref is the reference flow rate through the drying device and Flow rategem is the measured flow rate through the drying device measured over a drying cycle or CΔP is determined or calculated from the rpm of a compressor to which the drying device is connected.
