Abstract
A desalination system (1) for producing a distillate from a feed liquid includes: a steam raising device (2) having a liquid section (5) and a steam section (6) which are separated by a membrane system (7); a membrane distillation device (3) having a first steam section (11) and a liquid section (12) which are separated by a wall (14) and having a second steam section (13) which is separated from the liquid section (12) by a membrane system (15); and a heat exchange device (4) having a first liquid section (21) and a second liquid section (22), which are separated by a wall (23).
Claims18
A desalination system, comprising:
- a steam raising device comprising a liquid section separated from a steam section by a membrane system;
- a membrane distillation device comprising a first steam section separated from a liquid section by a wall, and a second steam section separated from the liquid section by a membrane system;
- and
- a heat exchange device comprising a first liquid section separated from a second liquid section by a wall;
- wherein the steam raising device, the membrane distillation device and the heat exchange device are implemented such that feed liquid fed into the second liquid section of the heat exchange device is heated by a brine liquid from the liquid section of the steam raising device, and such that permeate from the steam section of the steam raising device is condensed in the first steam section of the membrane distillation device, thereby heating heated feed liquid from the heat exchange device.
