Compliance options for Phase 2 of the Clean Air Act amendments of 1990 - a look at upgrading existing FGD systems
- Burns & McDonnell, Kansas City, MO (United States)
This paper analyzes the merits of a particular set of compliance options for Phase 2 of the Clean Air Act Amendments of 1990. In particular, the paper addresses the technical and economic merits of upgrading the flue gas desulfurization (FGD) systems installed on numerous power plants during the 1970s and 1980s. In many instances, these FGD systems can be upgraded to provide higher removal efficiencies at a relatively low cost. The paper discusses the technical issues associated with upgrading FGD systems, and the required level of capital investment for the various options. Operating cost impacts are quantified, also. In a case study analysis, the costs of the possible upgrade modifications are quantified in terms of dollars per ton of SO{sub 2} removed as determined from a recent study performed by Burns & McDonnell for the South Mississippi Electric Power Association (SMEPA). These costs are compared to the expected costs of allowance purchases. The conclusion is that upgrading some of these older FGD systems can be an economical compliance alternative for SMEPA and other utilities.
