McCain - Case Study
Longer life for gas engine after H2S removal
Potato processing company McCain in Lelystad, the Netherlands, receives biogas from both the anaerobic water treatment and the solids digester. The biogas - derived from fermenting potato peels - contains high levels of hydrogen sulphide. To prevent corrosion of the gas engine that uses the biogas as a power source, THIOPAQ® technology converts the hydrogen sulphide into elemental sulphur. THIOPAQ® technology smoothly handles the daily changing flow of biogas and proved very easy to operate.
