Modeling of the Cod Desalting Operation

Abstract

ABSTRACT: The objective of this study was to apply mathematical expressions commonly used in the analysis of mass-transfer processes to the study of the cod desalting operation to be able to predict the changes suffered by cod during the process. The NaCl concentration in the cod liquid phase at equilibrium was well predicted by using a mass balance. It was observed that the changes in the cod liquid phase concentration and the total weight changes throughout the process could be predicted by using a pseudo-diffusional approach or a biexponential equation, whereas a linear relation was observed between the NaCl cod liquid phase concentration and the cod density.
