Engineering Basis

  • Solvent baselines: MEA 3.7 GJ/t (commercial reference), MDEA 4.2, MDEA-PZ 3.0, piperazine 2.5, advanced 2.2.
  • Steam latent at 4 bara saturated: 2133 kJ/kg.
  • Auxiliary power 0.45 MWh/tCO₂: CO₂ compression (~0.35) + solvent pumps + blower.
  • Solvent circulation: kmol/h_amine = CO₂ captured / (rich − lean loading).
  • Standards: DOE NETL Cost & Performance Baseline (2022), IEAGHG, Rochelle 2009 (Science).
