Simulation for Desorption Regeneration and Verification

The model equations for desorption are the same as in Sect. 6.1. The object of simulation is also the experimental desorption of methylene chloride by Hwang [13] in the same column as adsorption. The purge gas is nitrogen at the inlet temperature of 298 K. 

The serial concentration profiles of the purge gas at different times are given in Fig. 6.7, which shows the details of the progress of the regeneration in the column. 

In order to compare the simulated result with experimental data, the radial average of purge gas temperatures at different times and at different heights (z = 0, 0.1, 0.2 m of the column) are calculated as shown in Fig. 6.10.
