A Variety of Hg Capture Solutions Are Available

摘要

While vacating the Clean Air Mercury Rule (CAMR) has postponed implementation of mercury capture to some extent, improvements in ways to capture - and monitor - Hg have continued to wend their way through the pilot testing phases and into the commercial market.rnOverall, all the coal plants in the United States emit about 50 tons of mercury per year. To place this into perspective, coal plants emit about a million tons of sulfur dioxide (SO_2) per year. CAMR was to ultimately reduce the 50 tons to 15 tons a year and Phase 1 was supposed to take effect January 1. But court challenges led to the vacating of the rule, thereby delaying indefinitely enforcement of the early phases of emission and monitoring compliance with federal rules.
