    摘要: 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.

    摘要: A distillation system having a plurality of chambers, an input conduit connected to each chamber to deliver an aqueous fluid to each chamber; a pressure reducing valve connected to the input conduit; a waste output conduit connected to a waste collection compartment of each chamber; and condensate output conduit connected to a condensate collection compartment of each chamber. An evaporation wall of each chamber is constructed to maintain an evaporation surface temperature that is greater than a condensation surface temperature of a condensation wall of each chamber. The aqueous fluid forms a fluid coating, which moves down the evaporation wall. A saturation pressure differential is created as water from the aqueous fluid evaporates from the evaporation wall and condenses on the condensation wall forming an aqueous condensate, which moves down the condensation wall and is collected as an aqueous distillate in the condensate collecting compartment.

    摘要: A water treatment system is configured to remove salt from a feed brine. The water treatment system includes a primary freezing chamber configured to receive the feed brine and a source of cooled intermediate cold liquid connected to the primary freezing chamber. The cooled intermediate cold liquid and feed brine are mixed within the primary freezing chamber, where ice particles are formed. The water treatment system includes a rotary separator connected to a discharge from the primary freezing chamber. The rotary separator is configured to separate solid ice particles from liquid components in the discharge from the primary freezing chamber. In some embodiments, the rotary separator includes a mesh inner filter tube that is configured for rotation within a solid outer filter tube, where the mesh inner filter tube allows liquid components to drain into the outer filter tube while conveying solid ice particles to an ice recovery tank.
