DOI:https://doi.org/10.2172/7368561· OSTI ID:7368561

This project will be the first North American demonstration of the Gas Suspension Absorption (GSA) system in its application for flue gas desulfurization. The purpose of this project is to demonstrate the high sulfur dioxide (SO[sub 2] removal efficiency as well as the cost effectiveness of the GSA system. GSA is a novel concept for flue gas desulfurization developed by F.L. Smidth miljo (FLS miljo). The GSA system is distinguished in the European market by its low capital cost, high SO[sub 2] removal efficiency and low operating cost. A 10 MW GSA demonstration system shall be installed and tested at the Tennessee Valley Authority (TVA) Shawnee Fossil Plant at West Paducah, Kentucky. The new GSA system will replace the existing spray dryer that was installed previously as a test unit. The experience gained in designing, manufacturing and constructing the GSA equipments through executing this project will be used for future commercialization of the GSA system. Results of the operation and experimental testing will be used to further improve the GSA design and operation. The specific technical objectives of the GSA demonstration project are to: (1) Effectively demonstrate SO[sub 2] removal in excess of 90% using high sulfur US coal. (2) Optimize recycle and design parameters to increase efficiencies of lime reagent utilization and SO[sub 2] removal. (3) Compare removal efficiency and cost with existing Spray Dryer/Electrostatic Precipitator technology.
