Materials and methods for mitigating halide species in process streams

Abstract

Materials and methods for mitigating the effects of halide species contained in process streams are provided. A halide-containing process stream can be contacted with mitigation materials comprising active metal oxides and a non-acidic high surface area carrier combined with a solid, porous substrate. The halide species in the process stream can be reacted with the mitigation material to produce neutralized halide salts and a process stream that is essentially halide-free. The neutralized salts can be attracted and retained on the solid, porous substrate.

What is claimed is: 
     
         1 . A medium for treating chloride species in a process stream, the medium comprising a reactant and a solid, porous substrate retainer, wherein the medium is configured to react with a chloride species in the process stream to produce an essentially chloride-free process stream and attract and retain the neutralized chloride salts on the substrate retainer, and wherein the reactant comprises tribasic potassium phosphate and a titanium dioxide carrier. 
     
     
         2 . The medium of  claim 1 , wherein the solid, porous substrate retainer comprises a reticulated ceramic material having a surface area of up to 300 square meters per gram.
