From Abstract: "The Vacuum-Freezing Vapor-Compression (VFVC) Process was evaluated on high salinity brackish water during the period from February 1968 through December 1969 by Colt Industries Inc., under O.S.W. Contract No. 14-01-0001-967 at Roswell, New Mexico. The 15,000 gpd VFVC test plant is mounted on a mobile trailer which was built by Colt Industries Inc. in their factory at Beloit, Wisconsin. Prior to operation at Roswell, the plant was operated at Wrightsville Beach, North Carolina to check out the system and to operate the trailer on sea water." Process Description: "A simplified diagram, Figure 2, shows both the essential components of the process and flow paths of the various streams in the system. Typical heat and mass balances are shown on Figures 3 and 4."

From Abstract: "Primary interest was placed on the scale formation problem. Significant improvements were made in the process and described in this report. Maintenance requirements were unusually high during the year, primarily as a result of cumulative corrosion damage over the last three years. The most significant damage was in the circulating pumps, the heat exchangers and feed piping. These and other failures are described."
