At the CAPE-OPEN 2019 Annual Meeting, Dr. Nefeli NOVAK will present on their UMR-PRU thermodynamic model. This work is co-authored with V. Koulocheris, A. Plakia, E. Petropoulou, Ch. Boukouvalas, V. Louli, G. Pappa, E. Voutsas also from National Technical University of Athens.
UMR-PRU is an EoS/GE thermodynamic model that has been developed by the Thermodynamics & Transport Phenomena Laboratory at NTUA. It combines the Peng-Robinson equation of state with the UNIFAC activity coefficient model. UMR-PRU has been successfully applied for predicting dew points, liquid dropouts and thermodynamic properties of natural gas and other petroleum fluids, as well as their phase equilibria with water, glycols, acid gases and mercury.
Some examples of process simulation with UMR-PRU will also be presented, such as a simplified natural gas processing plant, a TEG dehydration unit, and flash separators with attached reactions concerning acid gas-alkanolamine-water mixtures. Finally, some encountered challenges and possible new applications will be discussed.
