Treatment Chemical Case Studies by Bruce Keiser, Nalco. - Hot Topic Hour April 10, 2014

Nalco offers chemicals to solve the mercury emission problem for coal-fired boilers. One chemical is designed to inject in the boiler, another is injected in the scrubber and a third in the wastewater. The chemical quantities can be varied in order to compensate for process variables. For example the SCR does a better job of oxidizing mercury when the catalyst is new than later in the campaign. As the oxidation potential deteriorates the quantity of chemicals can be increased.
