•Application Note: Mercury Monitoring In A Cement Kiln
By Anand Mamidipudi, Thermo Fisher Scientific
Introduction
The Thermo Scientific Mercury Freedom system was originally designed to meet the requirements of the Clear Air Mercury Rule (CAMR), which was promulgated in 2005 for the U.S. Coal-fired Utility industry. Subsequently several hundred Mercury Freedom Systems were installed and operating in coal-fired power plants across the United States, passing stringent Relative Accuracy Test Audits (RATAs) under varying plant conditions. The CAMR was vacated in 2009, however many plants continue to operate the systems as required by their state or local agencies or, in some cases, to monitor vapor phase mercury emissions for effective process control. On September 9, 2010, the U.S. EPA promulgated the Portland Cement MACT rule, which requires all cement plants in the United States to monitor mercury on a continuous basis at the cement kiln.
This application note discusses the adaptability of the Mercury Freedom System to the unique conditions in a cement plant. Results of the Mercury Freedom System from a series of early installations in cement plants are discussed in relation to the new regulatory requirements and changing process flow conditions. Further, this application note shall examine the suitability of the current design of the Mercury Freedom System to the cement application and identify potential areas of improvement, if required.
