Abstract: A flash tank for concentrating fluids including a wall defining a rounded interior chamber bounded by a top elliptical head opposite to a bottom elliptical head; an inlet nozzle of the chamber; a steam chamber operatively engaged to the top elliptical head, wherein the steam chamber includes baffles and a conduit that directs condensate from the steam chamber to the level of liquid condensate; a gas discharge port operatively engaged to the steam chamber; and a liquid discharge port engaged to the bottom elliptical head below a vortex breaker. Changes to the flow passage of the steam chamber have been made by extending the baffles further into the internal chambers of the steam chamber.
