Patent ID: 8763426

Claim:
A method of separation of at least part of the solids from brine having an initial temperature T 1 , the method comprising: evaporating at least a part of said brine producing thereby a vapor stream having a first pressure P 1 and a slurry having a second temperature T 2 lower than said first temperature T 1 ; separating said part of the solids from said slurry, producing thereby a remaining liquid having a temperature equal to T 2 , wherein said solids remain in a solid state; compressing said vapor thereby increasing its pressure from P 1 to P 2 ; condensing said compressed vapor by having said remaining liquid absorb a latent heat released from said compressed vapor and discharging an outlet liquid of temperature equal to T 1 , the method further comprising adding of secondary soluble solids to said condenser reducing thereby a compression pressure ratio P 2 /P 1 required relative to its value without said addition.
