Specialty solution using the Stud-Liner product for the lining inside the dome of a biogas plant. Biogas Digesters made from Cement/Concrete are used for breaking down organic matter, by bio-digestion in anaerobic conditions to generate Biogas, which is a gaseous alternative fuel. The Biogas is a mixture of gases which predominantly includes Methane, Carbon Dioxide and Hydrogen Sulfide (H2S). The Concrete Dome of the Biogas plant is the place where the Biogas gets stored. However, the Hydrogen Sulfide present in the Biogas, reacts with the Lime/Calcium carbonate present in the cement surface of the dome, causing deterioration of the concrete.
