Performance

← Previous | Next →

Inputs for the performance of the MEA system in hydrogen production plants are entered on the Performance parameter screen. The following parameters are available:

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

•Number of Operating Absorbers: This is the total number of operating absorber vessels. It is used primarily to calculate capital costs. The value must be an integer. This parameter is read-only and is shown for reference.

•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. This parameter is read-only and is shown for reference.

•Compressor Isentropic Efficiency: This parameter compares the actual work done by the compressor on the captured CO2 stream to the ideal, frictionless work required to achieve the same outlet pressure.

•Compressor Mechanical Efficiency: This parameter accounts for physical friction losses, such as losses in mechanical seals, compressor bearing, and gears.
