Ash filter to remove hydrogen sulfide in landfill gas

Landfill gas can be used for CHP production if the concentration of the corrosive gas hydrogen sulfide is kept low. Therefore landfill gas needs to be pre-treated where hydrogen sulfide is removed in order to avoid expensive maintenance costs. In this project we want to test and validate a new method for purifying landfill gas from hydrogen sulfide. The method uses a bed of humid ash where landfill gas is led through the bed. The project may increase the utilisation of landfill gas and at the same time the ash is simultaneously stabilized.
