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 method of treating chloride species in a process stream, the method comprising:
 contacting the process stream with a medium comprising a reactant and a solid porous substrate retainer,   wherein the process stream comprises a hydrocarbon fluid and chloride species,   and wherein the reactant comprises tribasic potassium phosphate and a titanium dioxide carrier;   reacting the halide species in the process stream with the medium to produce a halide-free process stream and neutralized chloride salts; and   attracting and retaining the neutralized chloride salts on the substrate retainer.
