AirGasDetrit.mo#

Information#

The input is the thermal power, and the output is the electrical power required.

Description and Method#

The Air gas detrit package includes the Recombination and post dryer sections.

There are 5 models included in the airgas detritiation package:

• Low and High Temperature Heating
  • Heating load (kW) = Flowrate (kg/s) * Average heat capacity (kJ/kg.°C ) * (Required second stage temperature (°C) - Ambient temperature (°C))
• Compression of feed gas
  • Compressor energy (kW) = compressor work (kJ/kg) * hydrogen flowrate (kg/s)
• Regen heating
  • Constant Heating of ceramic energy (kW) = Mass of ceramic in one vessel (kg) * mol sieve heat capacity (kJ/kg.°C) * (final air regen temperature - ambient air regen temperature) * turnaround time (hour) / 3600
• Compression of regen gas
  • Compressor energy (kW) = compressor work (kJ/kg) * air flowrate (kg/s)
• Total Contingency factor
  • Electrolysis Power + Water heating + compressor work

Assumptions#

• Thermal Power exiting the reactor - 1 GW
• Worst case assumptions
  • Regen heating - Upstream knock out pot operating temperature - 40°C
  • Regen heating - Pressure of air from KOP - 3 bara
  • Comp regen gas - 'Mol sieve bed 1 turnaround operational time (from regen to saturation during operation) - 1 hr. This assumption is based off operational experience
