Modeling for extraction in column with recirculation of solvent
The input data were the same used in the configuration of single passage, presented in
the Table 1.
The Figure 3 shows the simulations results accomplished together with the experimental
data relating to the column extraction with solvent recirculation in the flow rate of 0.59;
2.4 and 4.7 cm3/min.
In the adjustment of parameters, tried to preserve the values for both configurations,
with and without recirculation (Table 2). Therefore, the experimental data simulation
represents an effort in the sense of assisting the results group through a single model
and with the broad parameters of all tests. In general, the model presented good
agreement with the experimental data, reproducing the inulin extraction tendency
appropriately along the process.
