ABSTRACT:
Device and method for removing dissolved organic acids from entrained liquid droplets in a waste gas stream comprising (1) heating the liquid droplets in the waste gas stream to the vaporization temperature, and (2) contacting the waste gas stream with a collecting means whereby the dissolved organic acids are deposited on the means of evaporization of the liquid droplets to thereby produce the heated gas stream substantially free of the liquid droplets. Additionally, the invention preferably relates to a reactor and method additionally comprising the steps of (1) introducing the waste gas stream having the dissolved organic acids removed through an inlet into a chamber containing a catalyst bed for oxidizing the pollutants, (2) passing the waste gas stream through a distributor plate containing a multiplicity of holes located between the inlet and the catalyst bed in a manner such that the waste gas is substantially uniformly distributed over the catalyst bed, (3) passing the waste gas through the catalyst bed while maintaining the catalyst bed at a temperature sufficient to sustain catalytic oxidation of the oxidizable pollutants, and (4) withdrawing through an outlet of the chamber the waste gas stream which has passed through the catalyst bed. Additionally, it is preferred that the method includes the step of removing the deposited organic acids from the above mentioned collecting means. The collecting means is preferably in the form of a thin fin parallel tube heat exchanger.
