System and method for reducing the visibility of exhaust emissions in a gas turbine system

A system, comprising:

• a pas turbine system having a flow path of an exhaust gas;
• and
• an emissions control system coupled to the gas turbine system, wherein the emissions control system comprises:
• a first reducing agent supply having a first tank of a first reducing agent, a first valve, and a first conduit fluidly coupled to the first tank, wherein the first conduit is fluidly coupled to the gas turbine system to introduce the first reducing agent into the flow path of the exhaust gas at a first position, wherein the first reducing agent comprises ethanol, alcohol, and/or hydrogen;
• a second reducing agent supply having a second tank of a second reducing agent, a second valve, and a second conduit fluidly coupled to the second tank, wherein the second conduit is fluidly coupled to the gas turbine system to introduce the second reducing agent into the flow path of the exhaust gas at a second position downstream from the first position, wherein the first and second reducing agents are different from one another;
• at least one sensor configured to obtain a feedback of one or more parameters of the gas turbine system, wherein the one or more parameters are indicative of a visibility of emissions of the exhaust gas;
• and
• a controller communicatively coupled to the at least one sensor and the first and second valves, wherein the controller is responsive to the feedback to reduce the visibility of the emissions of the exhaust gas by adjusting the first and second valves to adjust respective flows of the first and second reducing agents into the flow path of the exhaust gas.
