Development of a computational tool for designing multicomponent distillation columns

Abstract

AbstractThe present paper aims to develop new software to simulate multicomponent distillation columns. AmProS software can help students and professionals with different areas of expertise (e.g., chemistry, and chemical, mechanical, and food engineers) to solve and understand distillation and thermodynamics problems with critical thinking. A database of 113 hydrocarbon compounds was created to make the software use more dynamic. This user‐friendly software was developed using the “V model” methodology and Visual Basic language to carry out the design and establish the operation parameters of distillation columns. The user can choose between two preprogrammed equations of state (Peng–Robinson or Soave–Redlich–Kwong) for the calculation of thermodynamic properties. Two approaches were integrated in specific modules considering Shortcut and Rigorous distillation methods obtaining good accuracy (<10%) compared to the commercial simulator. Each module shows the key equations and message logs that guide the user through the software. The results of the input parameters' effects (key components, temperature, pressure, and feed composition) in the design and rating column are shown in Excel table formats (.xlsm) as well as in pdf files. This software was applied in different courses at School of Chemical Engineering at University of Campinas for user acceptance testing. These tests showed that AmProS is intuitive, information can be effortlessly found and it is easy to use to solve complex simulations. Chemical engineering students (undergraduates and graduates) and professionals in different fields can use this tool to expand their knowledge.
