Description

Despite an increasing proportion of gas-fired electric power generation resulting from growing availability of shale gas, coal remains the most commonly utilized fuel for commercial power generation in the world.  In South Africa, the proportion of electric power generated from coal is among the highest of any country, exceeding ninety percent in 2012, according to the World Coal Association.  Apart from implications of coal use for climate change, coal contains a range of potentially harmful trace constituents that are emitted in varying quantities and forms during coal combustion. This workshop will focus on the occurrence of mercury, other trace metals, and halogens in coal, and the geologic processes controlling their distribution.  We will also review formation of these emissions in flue gases of power plants and the potential for their capture.  Special emphasis will be given to trace elements in South African coals and their potential environmental impact.  We will also report on the current status of regulatory efforts by the U.S. Environmental Protection Agency to limit mercury and trace metal emissions from U.S. utility power stations through the Mercury and Air Toxics Standards (MATS), and efforts by the United Nations to limit global mercury use through the Minamata Convention.   This half-day workshop should be of interest to geologists, coal scientists, engineers, and environmental professionals wishing to know more about the source of trace constituents emitted from coal use and the impact of these emissions.
