Design of an Indirect Freezing Process Pilot Plant Based on Bulk Crystallization

摘要

This report covers the rationale and design of a 2000 gpd pilot plant to demonstrate indirect freezing with bulk crystallization for desalination of water. During the 1950's indirect freezing processes utilizing film or block freezing were investigated and found to be uneconomical. This is a study of a process that employs the simplicity of indirect freezing without the cost of scraped surface heat exchangers on poor thermal efficiency of film or block freezing. The pilot plant design is large enough to allow scaling to commercial size yet small enough to facilitate study of bulk crystallization.
