Summary

 

The Summary screen uses a two table format to display a summary of information about the solid sorbents TSA system.

The table on the left displays a summary of information that is key to the model calculations. This information is also available elsewhere in the model. The following important performance and cost factors are shown:

•Net Electrical Output: This is the net plant capacity, which is the gross plant capacity minus the losses due to plant equipment and pollution equipment (energy penalties).

•Annual Operating Hours: This is the number of hours per year that the plant is in operation. If a plant runs 24 hours per day, seven days per week, with no outages, the calculation is 24 hours / 365 days , or 8760 hours/year.

•Annual CO2 Removed: This is the amount of CO2 removed from the flue gas by the CO2 capture system per year.

•Annual SO2 Removed: This is the amount of SO2 removed from the flue gas by the CO2 capture system per year.

•Annual SO3 Removed: This is the amount of SO3 removed from the flue gas by the CO2 capture system per year.

•Annual NO2 Removed: This is the amount of NO2 removed from the flue gas by the CO2 capture system per year.

•Annual HCl Removed: This is the amount of HCl removed from the flue gas by the CO2 capture system per year.

•Flue Gas Fan Use: The flue gas has to be compressed in a flue gas blower so that it can overcome the pressure drop in the absorber tower. This is the electrical power required by the blower.

•HX Fluid Pump Use: This is the energy required to pump water and steam between the heat exchangers.

•Steam Compressor Use: This is the energy required to run the steam compressor for the heat exchangers.

•CO2 Compression Use: This is the electrical power required to compress the CO2 product stream to the designated pressure. Compression of CO2 to high pressures takes lot of power, and is a principal contributor to the overall energy penalty of a CO2 capture unit in a power plant.

•Auxiliary Power Produced: If an auxiliary natural gas boiler is used to provide steam and power for the solid sorbents TSA system, this is the additional electricity that it produces.

•Sorbent Regeneration Equiv. Energy: This is the electrical equivalent power for the regeneration steam required (taken from the steam cycle). The equivalent electricity penalty is about 10-15% of the actual regeneration heat requirement.

•Makeup Water for Aux. Cooling: (Only shown when anAir Cooled Condenser is configured.) This is the makeup water for the auxiliary cooling system needed when an Air Cooled Condenser is used as the plant cooling system.

The table on the right is a standard Cost of CO2 Avoided & Captured table.
