<p>A membrane distillation system includes a distillation vessel (16), an array of hollow fiber membranes (34) pervious to distillate vapor but impervious to feed solution and an array of hollow tubes (32) impervious to distillate vapor and feed solution but which allow thermal energy transmission. The system further includes a pump, a heat exchanger for heating the feed solution before it enters the hollow fiber membranes, and an outlet (27) for removing distillate from the distillation vessel. A method for removing distillate from a feed solution includes delivering the feed solution through hollow tubes spanning a distillation vessel, heating the feed solution, delivering the feed solution through hollow fiber membranes spanning the distillation vessel to create a vapor pressure differential between the hollow fiber membranes and a distillation volume within the distillation vessel, and removing distillate from the distillation vessel.</p> |
