Abstract

The present invention relates to an energy efficient and inexpensive Freeze Concentration System (FCS) to selectively freeze solvent from a solution using Heat Pump (HP) with heat transfer surfaces to extract and deliver heat to freeze the solvent and melt the frozen solvent using the heat from the HP. This process involves refrigeration of the solution, crystallization of water and separation of the formed ice. One or more sets of the heat extracting and/or heat delivery surfaces are intermittently operated as either freezing or melting surfaces to concentrate solution in a batch process or batch wise continuous process.
