Abstract
An electronic control system for regulating operational parameters in a pollution removal system. The pollution removal system may contain at least one reaction zone connected to a source of gas and a sorbent feeder containing a supply of sorbent. The system may include a pollutant concentration sensor that measures the concentration of at least one target pollutant in a gas exiting a reaction zone, a differential pressure sensor that measures the differential pressure across a reaction zone, a sorbent feed rate controller that regulates sorbent feed rate to the reaction zone, and a controller in communication with these elements. The controller may use the measured values to adjust sorbent feeder rate to ensure that the target pollutant concentration in a gas exiting the reaction zone is within an acceptable range and that differential pressure across the reaction zone is no greater than a predetermined level.
