SOAPP-CT Technology Modules

Combustion Turbine NOx Control Strategies

The SOAPP-CT Technology Module on Combustion Turbine NOx Control Strategies is an interactive, multimedia reference and evaluation tool for application of these systems in combustion turbine plants. You can quickly make informed decisions by varying key sensitivity parameters and comparing the change in performance data, equipment sizes, capital costs, O&M costs, and construction schedule for each technology alternative.

BACKGROUND

Nitrogen oxide (NOx) emissions from facilities burning fossil fuels have been a source of environmental and health concerns worldwide for more than 30 years. Controlling the emissions of NOx is an important economic decision facing companies currently burning or planning to burn fossil fuels in a combustion turbine. The main strategies for reducing NOx/CO emissions take two forms: (1) controlling formation by modifying the combustion process and (2) removing the pollutants in the exhaust gas through post combustion treatment. This SOAPP Technology Module addresses NOx reduction through design advances in the combustion control of combustion turbines.

SCOPE

The SOAPP-CT Technology Module on Combustion Turbine NOx Control Strategies includes technical reference information plus interactive conceptual design models for each of the following combustion turbine NOx control technologies:

  • steam injection
  • water injection
  • dry, low NOx combustors

The module includes discussions on basic principles and the major components of combustion turbine NOx control systems. More detailed information on each technology, including unique processes, components, and supporting systems, is also included in this module.

Technology performance; equipment sizing; capital, O&M, and differential fuel costs; and construction schedules are modeled for the combustion turbine NOx control technologies as a function of the following sensitivities:

  • combustion turbine model selection
  • number of combustion turbines
  • cycle type
  • fuel selection
  • secondary fuel usage factor
  • combustion turbine NOx emission limit
  • ambient dry bulb temperature
  • site elevation
  • installation type
  • unit capacity factor

Economic analyses are based on a static set of standard economic parameters when this module is used as a separate program. When this module is launched from within the SOAPP-CT WorkStation, up to 42 project-specific economic parameters are automatically imported into the module for the user's selected project. Included in these economic inputs are fuel cost, escalation rate, tax rate, capital structure, and contingencies. Default values for all module sensitivity parameters are also set from the values stored in user's selected project when this module is launched from within the SOAPP-CT WorkStation.
