ABSTRACT:
A batch crystallization system uses two stages of heat pumping. The first stage heat pump transfers latent heat of fusion from a freezing liquid to purified liquid. Sensible heat and compression work are transferred to the second stage heat pump for rejection to the environment. Ice formed in another chamber of the batch crystallization system is melted by direct contact with heated purified liquid.
