  • Patent number: 10850210
    Abstract: A system for brine water desalinization includes a first heat exchanger having an inlet plenum and an outlet plenum for a first fluid comprising a concentrate in a liquid. The first heat exchanger includes a shell side fluid inlet and a shell side fluid outlet for a second fluid comprising a higher concentrated liquid than the first fluid. The system also comprises pipes configured to direct the first fluid from the outlet plenum to a shell side fluid inlet of a second heat exchanger and to direct the second fluid from the shell side fluid outlet to an inlet plenum of the second heat exchanger. The system further includes pipes configured to produce desalinized water by a serial distillation of multiple steams from an nth number of heat exchangers into respective distillates thereof and a parallel product of brine waste thereof from the heat exchangers.
