  • Solar desalting process
    Patent number: 4376679
    Abstract: A solar desalting method and apparatus includes a storage tank for receiving heated sea water at a first rate from a solar collector during daylight hours and for delivering the same to a flash evaporator a second rate. The flash evaporator is connected for delivery of the evaporated and unevaporated portions of the feed water as the heating vapor and feed liquid, respectively, to a serially connected multi-effect film evaporator. Sea water is used to condense the vapor from the last evaporator effect as the distillate product of the system. The storage tank permits nighttime operation with the brine from the last effect and a portion of the cooling water being fed to the solar collector during the daytime and discharged at night.
    Type: Grant
