Abstract
A hybrid process and system for separating water from an inlet brine solution is disclosed. The hybrid process couples at least two different separation processes/systems. The inlet brine solution is fed into a first separation process, which produces a water distillate and a brine concentrate. The brine concentrate from the first separation process is then fed into the second separation process to further recover additional water. The excess heat from the second separation process is supplied to the first separation process.
Claims19
A system for concentrating a solution, comprising:
- a first separation module configured to separate water from an inlet solution stream to form a first concentrated solution and a first water stream;
- a second separation module configured to further separate water from the first concentrated solution to form a second concentrated solution and a second water stream;
- wherein a high temperature steam provides heat to the second separation module;
- a heating module comprising a first heating unit configured to utilize excess heat from the second separation module to heat an inlet solution before entering the first separation module for water separation;
- and
- a liquid conduit connecting the first separation module and the second separation module and is configured to deliver at least a portion of the first concentrated solution to the second separation module.
A process for concentrating an inlet solution, comprising:
- heating an inlet solution to form a heated inlet solution;
- feeding the heated inlet solution into a first separation process thereby producing a first concentrated solution and a first water stream;
- and
- feeding the first concentrated solution into a second separation process thereby producing a second concentrated solution and a second water stream;
- wherein the second separation process is configured to use a high temperature steam as an energy source, and an excess heat from the second separation process is delivered to the first separation process for heating the inlet solution.
