Regulations & Taxes

← Previous | Next →

The Regulations & Taxes parameter screen defines the emission constraints as they apply to the gases emitted from the power plant. Constraints for sulfur dioxide, nitrogen dioxides, particulates, and mercury are not needed due to the cleaner emissions from IGCC plants.

The emission constraints determine the removal efficiencies of control systems that capture particulates. The level of capture is set to comply with the specified emission constraints. As discussed later, however, user-specified values for control technology performance may cause the plant to over-comply or under-comply with the emission constraints specified in this screen. The following emission constraint is provided:

•Particulate Emission Constraint: The emission constraint of the total suspended particulates is a function of the fuel type and is used to determine the removal efficiency of particulate control systems (if used).

This screen also allows the user to enter the taxes on emissions in dollars per ton. The final costs determined from these inputs are available in the Stack results section of the IECM. The costs are added to the overall plant cost, not a particular technology. The following taxes on emissions may be specified:

•Sulfur Dioxide (SO2): The cost to the plant of emitting sulfur dioxide in dollars per ton.

•Nitrogen Oxide (equivalent NO2): The cost to the plant of emitting nitrogen oxide in dollars per ton.

•Carbon Dioxide (CO2): The cost to the plant of emitting carbon dioxide in dollars per ton.
