The suggested optimum variables are: heating time of 30min, cooling time
of 20 min, regeneration flow rate of 400 kmol/h and humidity of 0.001 in
air. Based on the results of optimization path given in Figure 9when
decrease in total operating costs and increase in recovery of VOCs is
desired, one can conculde that:
- Duration of heating stage should keep low as practicaly possible.
- Duration of cooling stage should be large enough.
- The small flow rate for regeneration and low humidity in air is
desired.
