Post Combustion NOx/CO Control SOAPP-CT Technology Module

BACKGROUND

Controlling the emissions of nitrogen oxides (NO_x) and carbon monoxide (CO) is an important economic decision facing companies currently burning or planning to burn fossil fuels in a combustion turbine. The main strategies for reducing NO_x-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 module addresses selective catalytic reduction (SCR) and CO oxidation post combustion NO_x-CO control technologies.

SCOPE

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

anhydrous injection

aqueous injection

anhydrous injection with CO abatement

aqueous injection with CO abatement

The module includes discussions on basic principles and the major components of combustion turbine combined cycle post combustion NO_x-CO 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 combined cycle NO_x-CO 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 NO_x control method

combustion turbine NO_x emission limit

stack NO_x emission limit

stack NH₃ emission limit

ambient dry bulb temperatures

site elevation

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.

	SOAPP-CT Technology Modules Post Combustion NO_x / CO Control
	The SOAPP-CT Technology Module on Post Combustion NO_X-CO Control is an interactive, multimedia reference and evaluation tool for application of these emission control systems in combustion turbine combined cycle 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.
