A complete mathematical model is proposed for the continuous countercurrent operation of a solvent sublation column. It takes into account all possible transport mechanisms in sublation. This is an extension of a previously published model for a lab-scale batch process. Experimental results on the continuous countercurrent removal of pentachlorophenol as a pentachlorophenolate + hexadecyltrimethyl ammonium bromide complex into decyl alcohol is also reported and checked against the model.
