Performance

← Previous | Next →

Inputs for the performance of the chemical looping system are entered on the Performance parameter screen. The following parameters are provided:

•Maximum CO2 Removal Efficiency: This parameter specifies the maximum efficiency possible for the absorber on an annual average basis. The value is used as a limit in calculating the actual CO2 removal efficiency for compliance.

•Absorber CO2 Removal Efficiency: This is the actual removal efficiency of the absorber alone.

•Limestone Purity: This is the purity of the limestone used.

•Other Removals:

•SO2 Removal Efficiency: This parameter measures the percent of SO2 removed by the CO2 capture system. The default efficiency is 100%.

•SO3 Removal Efficiency: This parameter measures the percent of SO3 removed by the CO2 capture system. The default efficiency is 0%.

•NO2 Removal Efficiency: This parameter measures the percent of NO2 removed by the CO2 capture system. The default efficiency is 0%.

•HCl Removal Efficiency: This parameter measures the percent of HCl removed by the CO2 capture system. The default efficiency is 0%.

•Particulate Removal Efficiency: This parameter measures the percent of particulates removed by the CO2 capture system. The default efficiency is 0%.

•Maximum CO2 Compressor Capacity: This is the maximum amount of CO2 product that can be compressed per hour at the specified pressure. See T&S Config for additional parameters.

•Number of Operating CO2 Compressors: This is the total number of operating CO2 compressors. It is used primarily to calculate capital costs. The value must be an integer.

•Number of Spare CO2 Compressors: This is the total number of spare CO2 compressors. It is used primarily to calculate capital costs. Up to two spare CO2 compressors may be specified.

•Makeup H2O Factor for Aux. Cooling: (Only shown when an Air-Cooled Condenser is used for plant cooling.) When CCS and an Air-Cooled Condenser are used, the CCS system uses an auxiliary cooling system. This parameter specifies the amount of makeup water required for the auxiliary cooling system.

•Calcium Looping Power Requirement: This is the electrical power required for the chemical looping system.
