![]() (Aspen–HYSYS is a process modeling tool that is widely used in the oil and gas industry.)Īdding ethane and chemical components heavier than -pentane, including a pseudo-component (e.g., ), requires only minor modification of the Mathematica code used in this Demonstration. The utility converts tower hydraulic information in PRO/II software to a file that can be read by KG-TOWER software. The results from both case studies are in perfect agreement with Aspen–HYSYSsimulation results, represented by colored circles. The free utility that integrates KG-TOWER ® rating software with PRO/II simulation software is now updated for the release of KG-TOWER software v 5.4. ![]() This is the most efficient operation of the depropanizer.Ĭase 2 shows a situation where the reflux and reboil ratios are improperly chosen and -butane exits at the top of the depropanizer along with propane. Two case studies are shown in the last two snapshots.Ĭase 1 shows a situation where pure propane is obtained as a distillate, and with no propane leaving at the bottom of the column. The orange, green, and blue curves represent the liquid-phase mole fractions of propane, -butane, and -pentane, respectively. If you could get enough energy from this item, I think your tomorrow will be more fulfilling. ![]() The Demonstration solves the full MESH (mass, equilibrium, summation, and enthalpy) equations and plots the composition and the temperature profiles inside the column. Equilibrium relationships and enthalpy values are calculated using the Soave–Redlich–Kwong equation of state (SRK EOS).
