Abstract

See full text

A method to reduce the deposition of solid sulfur (Ss(s)) in a natural gas producing well, is described wherein the inside of the pipes used in the well are coated with a coating comprising polar surface treated nanoparticles. The polar surface treated nanoparticles interact with the sulfur gas and interfere with the deposition of solid sulfur onto the surface of the pipe. The polar surface treated nanoparticles are selected from the group consisting of silica, alumina and silica-aluminate, metal sulfates and metal oxides.
