ABSTRACT:
A method of removing sulfur from a fluid including the steps of forming a container with a silver-containing mesh therein, passing the fluid into the container such that the fluid contacts at least a portion of the mesh, adsorbing the sulfur from the fluid onto the mesh, and removing the sulfur from the mesh. The step of removing includes the steps of forming a sulfur-removing solution, interacting the sulfur-removing solution with the adsorbed sulfur on the mesh, and contacting the mesh with an aluminum material during the step of interacting. The solution is heated prior to the step of interacting. The sulfur-removing solution includes the mixture of sodium carbonate with sodium chloride in an aqueous solution. Cayenne pepper is added to the mixture of sodium carbonate and sodium chloride. The mesh is formed by plating silver onto an exterior surface of the mesh and positioning the mesh into the container. The fluid can be aqueous, natural gas, oil, or fossil fuel by-products containing hydrogen sulfide or sulfur dioxide.
