Saline Water Conversion by Direct Freezing With Butane

Description: Report presenting a study of a plant to produce 10,000,000 gallons per day of fresh water from sea water. The process used is direct freezing brought about by the evaporation of a hydrocarbon refrigerant in contact with sea water, washing the ice free of saline liquor, and melting the ice to potable water by the condensation of butane vapor.

An Investigation of the Use of Acoustic Vibrations to Improve Heat Transfer Rates and Reduce Scaling in Distillation Units Used for Saline Water Conversion

Description: Report presenting a study to determine the feasibility of using acoustical energy to improve the economy of evaporator operation as related to saline water conservation. Some of the improvements to be sought are increased film heat transfer coefficients on the water side, possible promotion of dropwise condensation on the steam side, and reduced scale formation.

The Mechanism of Desalination by Reverse Osmosis

Description: Report describing the various parameters operative in fabricating desalination membranes for the Reverse Osmosis Process and the mechanism of separation. The bulk of the membrane contains huge quantities of capillary water which permits the movement of water through the body of the membranes at extremely rapid rates, there being essentially no pressure drop in this portion of the membrane.

Absorption-Multistage Flash Distillation Process

Description: "The major factors which influence the cost of water production from sea water by distillation methods are (1) the cost of fuel or energy required by the distilling plant, and (2) the required capital investment. Preliminary studies on the application of absorption or solution cycles to distillation methods for saline water conversion indicated that the fuel cost or thermal economy of a distillation plant could be improved by combining the distillation process with an absorption or solution cycle" (p. 1).

Research on Thermoelectric Heat Pumps

Description: From Results: "Prior to stating results achieved, let us first discuss the measurements we were able to make, and how these measurements might--or might not--be indicative of the objective we strove to reach. Tables I and II, and related Figs. 11 and 12, show the best results obtained. Final Columns of Tables I and II are believed to show, at least to a degree, how good or how poor our best sputtered films turned out to be, compared with top-quality Peliter semiconductor materials."

The Koppers Hydrate Process for Saline Water Conversion Experimental and Engineering Studies

Description: Report covering the research and development work on the Koppers Hydrate Process as a means of desalting sea water. The process is a chemical one, in which a hydrating agent, such as propane or dichlorodifluoromethane, and water combine to form insoluble crystals. Most of the work was carried out in bench-scale equipment or laboratory research.

Washing of Brine From Ice Crystals

Description: Report presenting experimental results for the washing of brine from beds of small plastic and glass beads, and from beds of ice particles prepared by partial freezing of brine. The data are analyzed in terms of a longitudinal-dispersion model which describes the blending of water and brine at the moving wash-water "front".

Operation of a Reverse Osmosis Desalination Pilot Plant

Description: Report demonstrating the technical feasibility of desalination by the Reverse Osmosis Process in a pilot plant cell containing 100 square feet of membrane area. A group of experimental tests are performed relating the desalination cell performance to the operating variables of brine flow rate, pressure, and brine concentration.

Vapor Compression Distillation using Secondary Heat Transfer Media

Description: Report discussing a particular method of converting saline water through vapor compression distillation at plants of different sizes. From Introduction: "This report is divided into three Sections (Books) each with its own index. Books I and II contain process and economic data for a 50,000 gpd pilot plant and a 10,000,000 gpd production plant. Book III contains process and economic data for high and low temperature units of 1,000,000 gpd size."
