LafargeHolcim, the largest producer?of cement in the world, uses Gasmet’s Continuous Mercury Monitoring (CMM) system to monitor mercury emissions and maintain a higher level of safety in cement production. They obtained the CMM system from RACI, a distributor of Gasmet’s systems operating in Slovenia and Croatia. A quick distributor and a reliable continuous Hg monitoring system with ...
Following the new EU BREF document for waste incineration, European cement plants have to implement the requirement to continuously monitor and abate mercury emissions. To enable this they will need to apply technologies that measure mercury in the raw gas and optimise sorbent ...

This partitioning of Hg into Hg°, Hg ~+, and Hgp is known as mercury speciation, which can have considerable influence on selection of mercury control approaches. ...
Gasmet Technologies (Finland) has published two White Papers on the monitoring of mercury emissions to air from industrial processes. The LCP BREF Guide provides an overview of current initiatives to reduce mercury emissions and explains how continuous mercury emissions monitoring can help ...

The Paper provides an overview of current initiatives to reduce mercury emissions and explains how continuous mercury emissions monitoring can help inform process ...
How nations choose to address these emissions could significantly impact global mercury pollution, since coal-fired power plants are responsible for about a quarter of mercury emissions worldwide. ...
For these reasons, monitoring and controlling emissions of mercury to air is important and steps are being taken in several countries to impose emission limits. In the European Union BREF guidance for Cement kilns (CLM BREF), mercury has a BAT-associated emission level of 0.05 mg/Nm3 (50 ...
This partitioning of Hg into Hg0, Hg 2+, and Hgp is known as mercury speciation, which can have considerable influence on selection of mercury control approaches. In general, the majority of gaseous mercury in bituminous coal-fired boilers is Hg2+. On the other hand, the majority of gaseous mercury in ...
Introduction In an effort to ensure that the UN Conference on Sustainable Development (Rio +20) generates meaningful outcomes, governments and other stakeholders increasingly support using the Conference to announce specific and time-bound commitments, and to agree on a “framework” to hold each other accountable for results. This so-called “Compendium of Commitments” has ...
Ultimately it will be one or two non-mercury HAPs that will determine the emission control fate of the coal- and oil-based power plant fleet. ...
Wet chemistry test methods do not provide real-time data often needed to minimize additive fuel rates used to control SO3 emissions. To both lower opacity levels while maintaining ESP fly ash conditioning, a facility will undertake a series of process control modifications; additive feed rates, and even comparison of different additives. ...
On July 11, 2008, the US Court of Appeals for the District of Columbia Circuit vacated (overturned) the US Clean Air Interstate Rule (CAIR). Adopted in 2005, CAIR was a centerpiece of the US Environmental Protection Agency’s (EPA) strategy to reduce multiple pollutants from major stationary sources. CAIR was expected to reduce power plant emissions in 28 eastern states and the District of ...
In June 1998 the New England Governors and Eastern Canadian Premiers (NEG--ECP) adopted a comprehensive regional Mercury Action Plan (MAP) with aggressive emission reduction and pollution prevention goals for the New England States, the Atlantic Provinces and Quebec. New Jersey and New York have also been active participants. The NEG--ECP MAP was motivated by, and based on, extensive data ...
EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). ...

Environmental Protection Agency (EPA) to be 48 t/yr, constituting the single largest anthropogenic source of mercury in the United States.1 Controlling mercury emissions from coal-fired power plants is currently the subject of intense legislative and regulatory debate. 2,3 In December 2000, EPA4 determined that ...
