Patent ID: 7396514

Claim:
An electronic control system for regulating operational parameters in a pollution removal system, the pollution removal system containing at least one reaction zone connected to a source of gas and a sorbent feeder containing a supply of sorbent, the system comprising: at least one pollutant concentration sensor that measures the concentration of at least one target pollutant in a gas exiting at least one reaction zone and generates a concentration output; a differential pressure sensor that measures the differential pressure across the at least one reaction zone and generates a differential pressure output; a sorbent feed rate control sub-element that adjusts or regulates sorbent feed rate to the at least one reaction zone; and a controller in communication with the at least one pollutant concentration and differential pressure sensors and the sorbent feed rate control sub-element, wherein the controller receives the concentration output and the differential pressure output and provides one or more outputs that adjust sorbent feeder rate to ensure that the target pollutant concentration in the gas exiting the at least one reaction zone is within an acceptable range and that differential pressure across the at least one reaction zone is no greater than a predetermined level.
