Performance

← Previous | Next →

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

•Maximum CO2 Removal Efficiency: (Only shown for 2-Stage Cascade) 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.

•CO2 Removed in Cross-flow Membrane: (Not shown for 2-Stage Cascade) This is the CO2 removal efficiency of the cross-flow membrane. It is shown for reference only.

•Absorber CO2 Removal Efficiency: (Only shown for 2-Stage Cascade) This is the actual removal efficiency of the absorber alone.

•CO2 Removed in Counter-current Membrane (%): (Not shown for 2-Stage Cascade) This parameter is only shown for reference in the "NETL 2-Step w/ Sweep" configuration. In the "2-Step w/ Air Sweep" configuration, it has the following options:

•90 (This is the default.)

•50

•CO2 Removed in Membrane System: (Only shown for 2-Step w/ Air Sweep) This is the CO2 removal efficiency of the membrane system alone, excluding the CPU. This value is shown for reference only.

•Overall Plant CO2 Removal Efficiency: (Only shown for 2-Step w/ Air Sweep) This is the overall CO2 removal efficiency of the membrane system. This value is shown for reference only.

•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 100%.

•NO2 Removal Efficiency: This parameter measures the percent of NO2 removed by the CO2 capture system. The default efficiency is 100%.

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

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

•Mercury Removal From CO2 Absorber: This parameter measures the percent of mercury removed by the CO2 capture system. The default is 0%.

•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.

•Membrane Separation Power Requirement: This is the electrical power required for the membrane system.
