This food processor was burning local landfill gas in their plant steam boilers as part of environmental initiatives at their facility. Mead & Hunt was selected to investigate treatment methods for the landfill gas to prevent further damage to the boilers and ancillary equipment. The results of the study led to the selection of a treatment system and budgetary pricing for the implementation of the proposed system. Untreated landfill gas was burned in two plant steam boilers until siloxane fouling of the boiler tubes caused a significant reduction in boiler efficiency. Additionally, sulfur compounds in the untreated gas and the subsequent SOX content in the flue gases caused significant corrosion of boiler economizers. Our team investigated treatment technologies such as activated carbon adsorption, silica adsorption, water scrubbing, pressure swing adsorption, and membrane separation. We assessed utilization of the landfill gas in a cogeneration system or in biogas boilers. Technologies were compared based on environmental sustainability, energy usage, financial feasibility, and reliability.
