FGD betterment: Asset preservation and revenue generation
- Sargent and Lundy, Chicago, IL (United States)
As a response to Phase 2 and beyond of the CAAAs of 1990, one of the key strategies that have been employed by many utilities is the use of existing FGD facilities to scrub the SO{sub 2} and generate more allowances to eliminate further need for compliance. Many of these units were built in 1970s. To keep these units operating in a very good condition through the year 2000 and beyond will require major capital improvements. Some of these units are not in good condition and are inviting major failures in the near future. Such failure would result in a major loss of revenue for the utility. For the units built in the 1970s, it is time to assess the condition of their FGD systems and to embark on capital improvement projects. These improvements can be categorized as high priority to low priority, and most work can be performed during scheduled outages. The condition assessment can be performed within 1 to 3 months. S and L`s experience in the last 2 years, with various plants and FGD technologies, could help other utility clients assess their FGD system and help them get ready for long-term SO{sub 2} compliance. The existing system can also be evaluated for its potential to lower maintenance costs and to generate additional SO{sub 2} allowances as a source of income. The maintenance cost can be reduced by identifying the key components in the FGD system that would result in improved efficiency of the equipment, thereby lowering auxiliary power needs. With careful planning, the potential exists to protect the sunk cost of the existing FGD systems and potentially to create a revenue stream related to the reduction in cost and the increased potential to produce SO{sub 2} allowances.
