摘要： A system and method to reboil a process or feed water stream in a distillation system does so in a liquid pool zone of a vessel as the stream is removed from a distillation column and comes into contact with a heating medium that is immiscible with and less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is partially vaporized, any solids present in the process stream together with the unvaporized process or feed water stream move into the heating medium. These solids and unvaporized liquids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized stream is returned to the distillation column.
