DWSIM

DWSIM is a free and open source chemical process simulator written by Brazilian chemical engineer Daniel Wagner O. de Medeiros. It is a comprehensive software that allows users to simulate a wide range of chemical processes, including distillation, absorption, extraction, among others. It supports multiple thermodynamic models, including ideal gas, Henry's law, NRTL, UNIQUAC, and more.

Users can create their own process flowsheets by adding equipment such as pumps, mixers, reactors, and separators. DWSIM provides a wide range of customization options, including the ability to adjust simulation parameters and modify the appearance of the flowsheet.

The software also includes a unit operation library that includes over 90 types of equipment for users to choose from. Additionally, DWSIM allows users to perform optimizations and sensitivity analyses on their simulations.

DWSIM has an active community of users with forums and documentation available for support. It is compatible with Windows and Linux platforms and can be downloaded from its official website.
