Epoxy-coated Steel Biogas tanks for the biogas project

The biogas produced by the anaerobic digestion unit is composed of combustible gas methane (50-75%), carbon dioxide (25-50%), water (H2O), nitrogen (N2), oxygen (O2), hydrogen sulfide (H2S), ammonia ( NH3) and trace elements (organic halogenation, siloxane, etc.). H2S, CO2, and water make biogas highly corrosive.

Whether you are fighting against greenhouse gases or rising energy costs, let Center Enamel help you build a durable Epoxy-coated steel anaerobic digester. We provide the best defense against storage tanks the highly corrosive digestive process that will test the limits of any storage tank technology.
