Abstract: A method and a system (12) for reducing plant (10) gas emissions by reducing ammonia/ammonium ion content in waste water W prior to the waste water W being evaporated in an evaporator device (7). As such, the method and the system (12) reduce the release of ammonia/ammonium ion into the flue gas FG stream thus reducing emissions of ammonia/ammonium ions to the environment or atmosphere and/or accumulation of ammonia/ammonium ions in downstream equipment such as a wet flue gas desulfurization system (13).

Abstract: A system and method for controlling oxidation of sulfites in a slurry. The system includes a tank having an inlet for receiving a slurry used in wet flue gas desulfurization. The tank also includes an inlet for receiving a gas. The inlet for receiving the gas is configured so that at least a portion of the gas received in the tank is dispersed through at least a portion of the slurry received in the tank. A sensor is configured to measure a sulfite concentration S1 of the slurry received in the tank. In some embodiments, the sensor is a sulfite analyzer. In other embodiments, the sensor is a virtual analyzer. The system includes a controller. Software executing on the controller generates a signal indicative of an adjustment of a flow rate of gas into the tank based at least in part on the sulfite concentration S1.

Abstract: An apparatus for evaporating waste water and reducing gas emissions includes an evaporator device configured to receiving a portion of flue gas emitted from a boiler unit and waste water to directly contact the flue gas with the waste water to cool and humidify the flue gas and to dry solid particulates within the waste water. In some embodiments, the waste water may be a component of a mixture formed by a mixer device prior to being contacted with the flue gas to humidify and cool the flue gas and dry solids within the waste water. An alkaline reagent as well as activated carbon can be mixed with the waste water prior to the waste water contacting the flue gas. Solid particulates that are dried within the cooled and humidified flue gas can be separated from the flue gas via a particulate collector.

Abstract: An apparatus for evaporating waste water and reducing flue gas acid gas emissions includes an evaporator device configured to receive a portion of flue gas emitted from a combustion unit and waste water for direct contact of the flue gas with the waste water to cool and humidify the flue gas, and to evaporate the waste water. An alkaline reagent as well as activated carbon may be mixed with the waste water prior to waste water contact with the flue gas. Solid particulates that are dried and entrained within the cooled and humidified flue gas can be separated from the flue gas via a particulate collector.
