Hidrouff Density Calculator : An Open-Source Software for Predicting Density of Complex Mixtures Using Peng Robinson Equation of State (Preos)

Commercial softwares dedicated to providing thermodynamic properties of complex mixtures in general have high-cost licenses and high computational cost, which makes its use limited for undergraduate students in remote classes or research tasks. Therefore, an open-source software was developed in Python, called HidroUFF Density Calculator, that is dedicated to predict- ing the density of complex mixtures using Peng-Robinson Equation of State (PREOS) as a resolution mechanism. Density was chosen for being one of the most requested thermodynamic properties. The proposed software was com- pared to a benchmark (UniSim Design), and its results were exactly equal or distant in less than 0.32%
