The Advantages of Equations of State in Form of the Helmholtz Energy for the Design of CCS-Relevant Processes Tobias Neumann, Roland Span

Abstract

Based on an isentropic adiabatic compression of pure CO2 typical approaches using the isentropic relation are compared with properties calculated from a fundamental equation of state in form of the Helmholtz energy. The comparisons focus on the estimated energy consumption of the compression, the estimated end temperature, and a reasonable thermodynamic behavior.
