Development of Generalized Equilibrium and Rate Models to Predict Ion Exchange Column Performance

Abstract

Generalized models to predict ion exchange column performance are developed in this work. An equilibrium model is developed to predict the initial leakages from an ion exchange column. The equilibrium model can handle both the hydrogen and the amine cycle. The effect of various factors on the initial leakages from a column are studied using this model. A generalized rate model is developed which can predict column effluent for a multi component system of ions with arbitrary valences. This model can also handle partially dissociativt: species like monovalent amines and carbonates.
