Abstract: Combustion turbine control systems are configured to operate combustion turbine systems in partial or no load while meeting emission targets. The combustion turbine system includes a combustion turbine, an electrical generator, a combustion turbine controller, a catalyst assembly, and/or other relevant equipment. Based on given operating constraints, such as load conditions and emission regulations, the combustion turbine controller may execute corresponding actions to control certain gas concentrations and/or gas mass flows in the exhaust gases in compliance with emission regulations. The corresponding actions may include, but are not limited to: controlling fuel and/or diluent injection(s) to combustor(s) to control combustion (e.g., combustion temperature) to manage combustion gas contents exiting from the combustor, controlling compressor bleed valve(s) to control the combustion temperature, controlling the catalyst assembly to process exhaust gases to be released into the environment, or a combination thereof.

Abstract: A system includes a downhole tool having a housing and a passage extending through the housing, where the passage includes an inlet configured to receive a flow of a wellbore fluid and an outlet configured to discharge the flow of the wellbore fluid. The downhole tool includes a heating element configured to heat the flow of the wellbore fluid and to enable the flow of the wellbore fluid to transition to a single-phase fluid flow within the passage. The downhole tool includes a phase composition sensor positioned adjacent the passage and configured to provide feedback indicative of formation of the single-phase fluid flow. The system includes a controller configured to monitor a power consumption of the heating element and to determine an enthalpy of the wellbore fluid based in part on the power consumption and the feedback from the phase composition sensor.
