Abstract: A method for removing ammonia from a condensate, the method comprising the steps of introducing a flue gas to a direct contact cooler, the flue gas comprising a gas selected from the group consisting of carbon dioxide, nitrogen, oxygen, water vapor, ammonia, and combinations of the same; contacting the flue gas with a water feed in the direct contact cooler to produce a cooled flue gas and the condensate; introducing the condensate to an ammonia stripper; contacting the condensate with an air feed to produce an air product and a wastewater; introducing a carbonic acid feed to the treatment unit, the treatment unit configured to modify the pH of the wastewater; and mixing the wastewater with the carbonic acid feed in the treatment unit to produce a treated water.

Abstract: A cooling system for a combustion turbine transition section. The combustion turbine includes a compressor assembly with a compressed air bleed line, a combustor assembly, a transition section with integral cooling channels, a turbine assembly with integral cooling channels. The compressor assembly is coupled to the combustor assembly, the combustor assembly is further coupled to the transition section, the transition section is further coupled to the turbine assembly. The compressor assembly, combustor assembly, transition section, and turbine assembly form a flow path. The cooling device includes a compressed air steam generator, a feed water source coupled to, and providing water to, the compressed air steam generator, a steam pipe coupled to the transition section cooling channels and the compressed air steam generator. The compressed air bleed line passes through the compressed air steam generator. In operation, the compressor compresses the ambient air thereby raising the ambient air temperature.
