The objective of this course was to provide participants with an appreciation of mercury transformations, measurement, speciation, and mercury control options. The selection of mercury control options depends upon the speciation and transformation of mercury in combustion flame and postcombustion flue gas. Coal composition, boiler operating conditions, and postcombustion conditions influence the distribution of mercury in its elemental, oxidized, and particulate forms. Mercury speciation along with the configuration of air pollution control devices dictates mercury control options.

Examples of current experience with mercury emission control and measurement were emphasized. Examples were presented on sorbent options, oxidation additives, and sorbent enhancement based on bench-, pilot-, and full-scale testing of mercury control options. In addition, the challenges of mercury measurement were discussed. The short course concluded with examples of the use of computer models for predicting mercury speciation and control.
