Maximizing profit and minimizing losses in controlling air pollution
First Claim
1. A controller for directing operation of an air pollution control (APC) system performing a process to control emissions of a pollutant, having one or more controllable operating parameters, comprising:
- an interface configured to receive financial data associated with the operation of the APC system; and
a control processor having logic (i) to determine a target set point of each of at least one of the one or more controllable operating parameters that will maximize profits or minimize losses from the operation of the APC system, based on the received financial data and (ii) to direct control of each of the at least one controllable operating parameter of the APC system based on the determined target set point.

Abstract
A controller directs the operation of an air pollution control (APC) system performing a process, having one or more controllable operating parameters, to control emissions of a pollutant. An interface receives financial data associated with the operation of the APC system. A control processor determines a target set point of each of at least one of the one or more controllable operating parameters that will maximize profits or minimize losses from the operation of the APC system, based on the received financial data. The control processor also directs control of each of the at least one controllable operating parameter based on the determined target set point for that parameter.

15. A method for directing control of a process, for controlling emissions of a pollutant, having one or more controllable process parameters, comprising:
-
determining a target set point for each of at least one of the one or more controllable process parameters that will maximize profit or minimize losses from the performance of the APC process, based on financial data associated with the performance of the APC process; and
directing control of each of the at least one controllable process parameter based on the determined target set point for that controllable process parameter. - View Dependent Claims (16, 17, 18, 19, 20)

21. A wet flue gas desulfurizing system, comprising:
-
a wet flue gas desulfurizer operable (i) to receive SO2 laden wet flue gas, (ii) to expend power to apply oxidation air and limestone slurry to remove SO2 from the received SO2 laden wet flue gas and produce gypsum, and (iii) to exhaust desulfurized flue gas;
a controller configured (i) to receive financial data associated with operation of the of the wet flue gas desulfurizer and (ii) to determine target set points for a first parameter corresponding to an amount of the applied oxidation air and for a second parameter corresponding an amount of the applied limestone slurry, which will maximize profit or minimize losses from the operation of the wet flue gas desulfurizer, based on the received financial data and on one of a neural network process model and a non-neural network process model representing a relationship between each of the one or more controllable operating parameters and the emitted amount of pollution, and (iii) to direct control of the first parameter and the second parameter based on the determined target set points. - View Dependent Claims (22, 23)

24. A selective catalytic reduction (SCR) system, comprising:
-
a selective catalytic reducer operable (i) to receive NOx laden flue gas, (ii) to apply ammonia and dilution air to remove NOx from the received NOx laden flue gas, thereby consuming ammonia and controlling emissions of NOx, and (iii) to exhaust reduced NOx flue gas; and
a controller configured (i) to receive financial data associated with operation of the selective catalytic reducer and (ii) to determine a target set point for a parameter corresponding to an amount of the applied ammonia, which will maximize profit or minimize losses from the operation of the selective catalytic reducer, based on the received financial data and on one of a neural network process model and a non-neural network process model representing a relationship between each of the one or more controllable operating parameters and the emitted amount of pollution, and (iii) to direct control of the parameter based on the determined target set point. - View Dependent Claims (25, 26)
