Method of introducing silica nanoparticles to reduce h2s in a liquid or gas stream

Abstract

A method to reduce the amount of H2S in a Liquid or Gas Stream, the method comprising the steps of a) Operating an industrial process that has H2S in a liquid or gas stream or both a liquid and gas stream associated with it, wherein the industrial process comprises connected pipes that allow liquid and gas to travel from one location to another within the process, b) Injecting a silica nanoparticle mixture into an industrial process that has H2S in a liquid or gas stream or both a liquid and gas stream associated with it, wherein the silica nanoparticle mixture may be in a colloidal state or in a dry state; and c) Presenting the materials in the silica nanoparticle mixture in such a way that they react with the H2S resulting in the reduction of H2S in the liquid or gas produced fluid. In certain embodiments, the silica nanoparticle mixture includes silica nanoparticles with or without a surface treatment, and one or more chemicals selected from the group consisting of triazines, alcohols, polyols, ketones, aldehydes and hemiacetals.
