Demonstration of Wellman-Lord/Allied Chemical FGD technology: acceptance test results

The report gives results of acceptance tests of Wellman-Lord/Allied Chemical flue gas desulfurization (FGD) technology. Process performance guarantees were met or exceeded. During the 12-day Design Load test, the plant was operated at the design condition of a boiler flue gas output rate equivalent to 80% of the maximum boiler load of 115 MW gross. During the 83-hour High Load test, the plant treated flue gas volumes equivalent to 95% of maximum boiler load. SO2 removal of 90% or better was achieved. Particulate emissions did not exceed 0.1 lb/million Btu of boiler heat input. The consumption of steam, natural gas, and electrical power was less than the performance guarantee requirements at Design Load conditions. Soda ash consumption was less than the limit set by the performance guarantees. Finally, sulfur product purity was greater than 99.5%.
