Field Evaluation of Natural Gas and Dry Sorbent Injection for MWC Emissions Control

    Research output: NRELTechnical Report


    The Institute of Gas Technology (IGT), in cooperation with the Olmsted Waste-to-Energy Facility (OWEF) and with subcontracted engineering services from the Energy and Environmental Research Corporation (EER), has completed the detailed engineering and preparation of construction specifications for an Emissions Reduction Testing System (ERTS). The ERTS has been designed for retrofit to one of two100-ton/day municipal waste combustors at the OWEF, located in Rochester, Minnesota. The purpose of the retrofit is to conduct a field evaluation of a combined natural gas and sorbent injection process (IGT's METHANE de-TOX8M, IGT Patent No. 5,105,747) for reducing the emissions of oxides of nitrogen (NOx), hydrochloric acid (HCI), oxides of sulfur (SOx), carbon monoxide (CO), total hydrocarbons(THC), and chlorinated hydrocarbons (dioxinslfurans). In addition, the design includes modifications for the control of heavy metals (HM). Development of the process should allow the waste-to-energy industry to meet the Federal New Source Performance Standards for these pollutants at significantly lower casts when compared to existing technology of Thermal deNOx combined with spray dryerscrubber/fabric filters. Additionally, the process should reduce boiler corrosion and increase both the thermal and power production efficiency of the facility.
