Patent number: 11285439Abstract: A method for the reduction and prevention of mercury emissions into the environment from combusted fossil fuels or other off-gases with the use of peracetic acid is disclosed. The peracetic acid is used for the capture of mercury from the resulting flue gases using a flue gas desulfurization system or scrubber. The method uses peracetic acid in conjunction with a scrubber to capture mercury and lower its emission and/or re-emission with stack gases. The method allows the use of coal as a cleaner and environmentally friendlier fuel source as well as capturing mercury from other processing systems.Type: GrantFiled: October 10, 2018Date of Patent: March 29, 2022Assignee: ECOLAB USA INC.Inventors: Nicholas R. Denny, Bruce A. Keiser, David M. Dotzauer, Wayne M. Carlson

This thermal stabilization reduces mercury release from the synthetic gypsum. Illustrative, non-limiting examples of sulfur-containing compounds include inorganic sulfides, organic sulfides, organic compounds containing nitrogen and sulfur, organic compounds containing oxygen and sulfur, and polymers containing sulfur.Type: GrantFiled: August 7, 2017Date of Patent: May 19, 2020Assignee: ECOLAB USA INC.Inventors: Bruce A. Keiser, Wayne M. Carlson, Nicholas R. Denny, Jianwei Yuan, Tommy Hung-Ting Chen
