In these figures, the concentrations and transfers are shown as a
function of the number of extraction column stages. It can be
observed that the five consecutive processing steps used to obtain
RBOd-LE, which were performed according to the scheme shown in
Fig. 3, were equivalent to approximately 10 theoretical stages in
the PRDC. The estimated number of theoretical stages in each step
of the deacidification process and their uncertainties calculated by
error propagation of Eq. (1) are presented in Table 6. In this table,
the sensitivity analysis results for Eq. (1) are also presented. This
analysis was performed using a 0.0001 deviation in the free fatty
acid mass fraction.
