DWSIM is an open-source CAPE-OPEN compliant chemical process simulator for Windows, Linux and Mac. DWSIM is built on top of the Microsoft .NET and Mono Platforms and features a Graphical User Interface (GUI), advanced thermodynamics calculations, reactions support and petroleum characterization / hypothetical component generation tools.

DWSIM is able to simulate steady-state, vapor-liquid and vapor-liquid-liquid equilibrium processes with the following Thermodynamic Models and Unit Operations:

• Thermodynamic Models: PC-SAFT, Peng-Robinson, Soave-Redlich-Kwong, Lee-Kesler, Lee-Kesler-Plöcker, UNIFAC(-LL), Modified UNIFAC (Dortmund), UNIQUAC, NRTL, COSMO-SAC, Chao-Seader, Grayson-Streed and Raoult's Law.
• Unit Operations: CAPE-OPEN Socket, Mixer, Splitter, Separator, Pump, Compressor, Expander, Heater, Cooler, Valve, Pipe Segment, Shortcut Column, Heat exchanger, Reactors (Conversion, PFR, CSTR, Equilibrium and Gibbs), Distillation column, Simple, Refluxed and Reboiled Absorbers, Component Separator and Orifice plate.
• Utilities: Phase Envelope, Natural Gas Hydrates, Pure Component Properties, True Critical Point, PSV Sizing, Vessel Sizing, Spreadsheet and Petroleum Cold Flow Properties.
• Tools: Hypothetical Component Generator, Bulk C7+/Distillation Curves Petroleum Characterization, Reactions Manager and User Component Creator.
• Process Analysis and Optimization: Sensitivity Analysis Utility, Multivariate Optimizer with bound constraints.
• Extras: Support for Runtime Scripts, Plugins and CAPE-OPEN Flowsheet Monitoring Objects.
