The performance of a continuous, vertical, dense‐bed column crystallizer is evaluated by comparing experimental and predicted column temperature profiles and by examining product composition at various operating conditions. The separation obtained in an eutectic system is modeled by a component conservation equation coupled with a nonadiabatic energy balance equation. The critical parameter in the analysis is the axial dispersion coefficient and the measured values of this coefficient were similar in magnitude to those reported for ice washing columns. The dense‐bed column apparently achieves nearly ideal plug flow.
