Preliminary Estimates of Performance and Cost of Mercury Emission Control Technology Applications on Electric Utility Boilers: An Update.

摘要

The Environmental Protection Agency has recently proposed a reduction in mercury emissions from coal-fired power plants. There are two broad approaches under development to controlling mercury emissions from coal-fired electric utility boilers: (1) powdered activated carbon (PAC) injection, and (2) multipollutant control, in which Hg capture is enhanced in existing and new sulfur dioxide (SO2), nitrogen oxides (NOX), and particulate matter (PM) control devices. To help inform the recent EPA rulemaking proposal, estimates of performance levels and related costs associated with the above mercury control approaches were developed. This work presents these estimates.
