Dear Arimiyawo,

Antoine Equation Parameters for carbon dioxide gas

Log10(P) = A − (B / (T + C))

    P = vapor pressure (bar)

    T = temperature (K)

 Accurate modelling of thermodynamic properties for CO2 absorption in aqueous alkanolamine solutions is essential for the simulation and design of such CO2 capture processes.CO2 capture by absorption with aqueous alkanolamines is considered an important technology to reduce CO2 emissions from fossil-fuel-fired power plants and to help alleviate global climate change. Differential Evolution (DE) algorithm is a new heuristic approach mainly having three advantages; finding the true global minimum regardless of the initial parameter values, fast convergence, and using few control parameters. coefficient of CO2 in the mixed solvent of water and amine, is the system pressure, the mole fraction of CO2 in the vapor phase, and the equilibrium CO2 mole fraction in the liquid phase. Henry’s constant in the mixed solvent can

If you use Aspen Plus, CO2 and water are available in the databank, so the PLXANT constants can be obtained by selecting 'retrieve parameter'.  

Thank Prem and Ceecilia for your responses
