ABSTRACT:
A vapor compression type distillation apparatus and method is provided for distilling brackish water or seawater wherein increased efficiency can be achieved by virtue of an arrangement and operation which maximizes the average effective temperature differential between steam being condensed and the water being vaporized. Thus a vertical shell and tube vaporizer is provided which includes an array of tubes which array has a width substantially greater than its depth. The liquid discharged from the upper ends of the tubes is caused to flow downwardly in a downtake passage into a body of water at the lower end of the vaporizer along substantially the entire width of the array. Feed water is fed into the body of water at the lower end of the vaporizer at one end of the array and blowdown is taken from such body at the other end of the array.
