Summary

← Previous | Next →

The Summary screen uses a two table format to display a summary of information about the chemical looping 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.

•Oxidant Blower Use: This is the power required for pumping the oxidant exiting the air separation unit.

•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 a lot of power, and is a principal contributor to the overall energy penalty of a CO2 capture unit in a power plant.

•ASU Power Use: This is the electrical power used by the air separation unit.

•Auxiliary Power Produced: This is the power produced by the heat recovery system.
