Process for concentrating dilute sulphuric acid in an evaporator.

摘要

Process for reducing solute in a vapour stream, particularly in concentrating solutions in an evaporator (2) wherein the solution is heated to volatilize solvent, by (a) the utilization of a wire mesh mist eliminator pad (16) and (b) spraying a liquid uniformly over the surface of the mist eliminator pad (16). The process has been particularly advantageous in the multistage concentration of corrosive products particularly in the concentration of a 60-70% sulfuric acid solution to about 93 percent.
