Mercury Reduction Through Treatment Chemical Selection

Description:Summary: The purpose of this project is to reduce mercury that may be reaching Lake Superior through cooling water and effluents from power plants, boilers and other facilities. Cooling water is treated with pH altering chemicals, such as acid and caustic soda. Certain feedstock chemicals used to alter the pH have been found to contain high levels of mercury. For example, sulfuric acid produced as a by-product from a lead smelter was found to have significantly higher levels of mercury than sulfuric acid from a copper smelter. The project strategy is to promote the switch from high mercury to low mercury chemical feedstocks.

Environmental Results/Products: MPCA compiled a list of the boilers in the four Minnesota counties bordering Lake Superior. A survey for boiler operators was distributed at a State-sponsored boiler workshop. Only 10 operators filled out the survey, but those that did indicate that they would be willing to switch to non-mercury caustic if the price was the same. A few operators indicated they would be willing to pay more. MPCA collected information on mercury concentrations in various grades of caustic soda from, a chemical supplier and a chlor-alkali producer and the Western Lake Superior Sanitary District (WLSSD). Up-to-date cost information is needed.

MPCA will be working with boiler operators on solid waste management issues. Some boilers use high pressure steam gauges that contain large amounts of mercury. For example, one steam gauge collected during a WLSSD mercury amnesty project contained 30 pounds of mercury. Some boilers may also contain mercury switches.
