【 摘 要 】

This is a Technical Report under a program funded by the Department of Energy's National Energy Technology Laboratory (NETL) to obtain the necessary information to assess the viability of lower cost alternatives to commercially available activated carbon for mercury control in coal-fired utilities. Novel sorbent evaluations at We Energies' Pleasant Prairie Power Plant (P4) Unit 1 (no SCR in place) have been completed. Nineteen sorbents were evaluated for mercury control. A batch injection rate of 1 lb/Mmacf for 1 hour was conducted for screening purposes at a temperature of 300 F. Four sorbents were further evaluated at three injection rates and two temperatures. The multi-pollutant control test system (PoCT) was installed on P4's Unit 2 (with an SCR) and sorbent evaluations are continuing. Evaluations will continue through the end of January 2004. Tests and analysis on samples from Powerton and Valley to yield waste characterization results for the COHPAC long-term tests are continuing. A no-cost time extension for work to be completed by March 31, 2004 was granted by DOE/NETL.
