BUILD IT TO LAST Biogas Storage Tank For Biogas Project

Center Enamel cooperates with the world's leading biogas engineering company to provide a complete set of biogas digester solutions for biogas projects. 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 (organohalides, siloxanes, etc.). H2S, CO2 and water make biogas very corrosive.

Whether you are dealing with greenhouse gas emissions or rising energy costs, Center Enamel can help you build durable anaerobic digesters. Center Enamel GFS tanks offer the best defense against highly corrosive digestion processes that will test the limits of any storage tank technology.
