Key Takeaway Key Takeaway: Ice crystals are mechanically washed of brine in Freon, resulting in a process called "Freon removal" that can be used to produce fresh melt water.
Abstract
Ice crystals formed in a solution, such as in the ice crystallization conversion of sea water to fresh water, are washed in organic liquid, such as Freon, at a temperature below 32 DEG F. The ice crystals float upward in the Freon to be restrained by an upward sloping screen. The ice crystals are agitated in the liquid Freon by vibration of the screen and/or by jets of liquid Freon directed downward through the screen. Brine, which is thus mechanically washed from the crystals, floats upward through the screen to be collected above it. Washed ice crystals move up the screen to be collected, melted, and have the Freon separated from the fresh melt water.
