Abstract

See full text

A method for desalinating a brine includes the use of a cooled intermediate-cold-liquid (ICL), which combines with the brine in a crystallization or freezing tank to produce a slurry of ice, brine, and ICL. The method includes steps for separating the ICL, ice and brine, and returning the separated ICL to the source of cooled ICL tank. The method concludes with the steps of passing the separated brine to the crystallization tank, and melting the separated ice to form desalinated water. The method is significant in that it produces desalinated liquid water and solid salts. The combination of superior heat transfer with high quality purified water and competitive desalination economy makes the disclosed freeze desalination technology an attractive solution for desalination of highly concentrated brines produced in a variety of industries, including but not limited to the oil and gas industry and reject brine management.
