Considering the Options: Making the Most of Emissions Reduction Requirements
This paper focuses on strategies for reducing the overall cost of emissions compliance. It explores the possibilities for more aggressive and less aggressive retrofit strategies, each offering compliance. The paper also looks at the combination of retirement and uprates within a facility for meeting mandated emissions standards. The following three scenarios are evaluated, based on maintaining the FERC permitted plant horsepower, while minimizing the cost of compliance for a 10 unit station: (1) A station wide retrofit for a moderate reduction; (2) A combination of more and less aggressive control techniques for compliance; (3) A combination of aggressive control techniques and retirement. The paper concludes with a brief case study of an actual implementation that used a combination of retirement and uprating to meet its compliance targets.
