While DWSIM (free/open-source) provides a robust platform for steady-state and basic dynamic simulation—including thermodynamic packages, unit operations, and physical properties—DWSIM Pro enhances this foundation with tools that accelerate decision-making in industrial settings. Key Features and Advantages of DWSIM Pro
Simulating amine-based absorption columns and cryogenic CO2 purification processes. Specialty Chemicals and Pharma
DWSIM Pro is the commercial, enterprise-ready extension of the standard open-source DWSIM process simulator. While the standard version remains free and highly capable, the Pro version is specifically engineered for professional engineers, consultancies, and industrial plants requiring enhanced calculation speeds, proprietary thermodynamics, cloud collaboration, and dedicated technical support. dwsim pro
While the open-source version of DWSIM remains a powerful tool for students and researchers, is designed specifically for commercial and industrial applications. It is built by the Simulate 365 Team , providing a stable, supported environment for complex engineering tasks. Key distinctions include:
The free version’s YouTube tutorials cover basics. For Pro features, look for: While the standard version remains free and highly
REFPROP also handles cryogenic processes. A documented example uses a novel coolant fluid (R1234ze, a hydrofluoroolefin) in an air conditioning system. Other applications include CO₂ pipeline transport in the supercritical region where common equation‑of‑state models lose accuracy.
DWSIM Pro is a versatile tool that shines in numerous industrial and research applications: Reported use cases include polymerization reactions
Unlike the community-driven support of the open-source version, Pro users have access to dedicated private technical support.
The free DWSIM includes full steady‑state and dynamic simulation, the complete library of thermodynamics (Peng‑Robinson, NRTL, UNIFAC, etc.), standard unit operations (distillation columns, reactors, heat exchangers, pumps, valves, compressors), Python and IronPython scripting, CAPE‑OPEN interoperability, an Excel Add‑In for thermodynamic calculations, and specialized utilities (phase envelope, PSV sizing, vessel sizing, hydrate calculations, spreadsheets). The free version runs on Windows, Linux, macOS, Android, and iOS, works offline without internet, and is widely used in education and research.
The software supports a wide array of equilibrium processes, including: Vapor-Liquid (VLE) Vapor-Liquid-Liquid (VLLE) Solid-Liquid (SLE) Aqueous electrolyte equilibrium
The unit operation in DWSIM Pro enables modeling of transient behavior, reaction kinetics, and product quality over time. It supports three calculation modes: isothermal, adiabatic, and advanced mode with jacket for detailed thermal simulation. Reported use cases include polymerization reactions, fermentation (bioprocesses), and specialty chemical production.
