Abstract
An integrated system [] is described for reducing operating costs of power plants while keeping gaseous pollutants in exhaust flue gasses, such as Mercury (Hg), below acceptable limits. Controller [] monitors and controls operation of a scrubber [], activator injection system [], sorbent injection system [] and a filter []. Scrubber [] provides a neutralizer to remove SOemissions. Activator injection system [] provides and activator that increases affinity of the pollutant gasses for a sorbent. Sorbent injection system [] employs novel low friction injection lances [] that evenly distribute the sorbent particles. A filter [] collects the sorbent particles that cake onto filter bags [] that are periodically cleaned. A controller [] receives the costs of materials consumed and the filter bag life for the plant and performs an optimization of the multiple variables to minimize costs while keeping the pollutant emissions below a prescribed limit.
