DEVICE FOR THE DEPOSITION AND CONCENTRATION OF SULFURIC ACID AND SULFUR DIOXIDE

摘要

A process for the separation of sulfuric acid and sulfur dioxide from gas streams is described, wherein the gas stream is cooled in a first heat exchanger with a cooling medium, the precooled gas stream in a second heat exchanger, which is flowed through by the gas flow from bottom to top in countercurrent to a flow of cooling gas , Is cooled and the cooled gas stream then flows through a wet electrostatic filter from bottom to top to remove the remaining sulfuric acid droplets, wherein the wet electrostatic precipitator is followed by a scrubber for the separation of residual sulfur dioxide
