Process Modeling and Design - ChE
A free, equation-based environment for process modeling. Includes an object-oriented
model-description language. Released under GNU for Windows and UNIX platforms.
Integrated steady-state and dynamic process simulator based on Aspen Plus and Aspen Custom
Information about this standard process simulation package for steady-state modeling from
Chemstations' PC-based general purpose process simulation program.
Chemical Process Modeling PC
Excel add-ins, Mathcad and Maple files from Lee Partin for chemical plant modeling,
distillation design calculations, pinch analysis... The software is copyrighted but free
for personal or educational use.
Package of integrated chemical reactor simulation tools for Windows 95/NT from Kinetic
Technologies, Russia. A PowerPoint presentation of the program (3.8 MB) can be downloaded
after completing a form.
DESIGN II for Windows
WinSim's general-purpose process simulator developed specifically for MS Windows
platforms. The full package is available free for download but you must register to get a
2 week password.

Report about a system that provides "flowsheeting", i.e. mass and energy balance
computation, across the WWW. A VRML viewer (e.g. Live3D integrated in Netscape Navigator)
is required to see the generated flowsheet.
Steady state process simulator for the PC from Hyprotech. Incorporates a wide range of
unit operations, heat exchanger design, compressors, valves, and extensive thermophysical
Integrated package from Hyprotech that covers all process simulation and real-time
applications. Flowsheet based dynamic and steady state process modeling. For MS Windows 32
Somewhat limited and awkward to use MS-DOS program for chemical process material balance
simulation and parameter optimization. But it's free. 240 kB to download.
PC-based program from Prode for simulating chemical processes.
General hydrocarbon process simulator from Bryan Research & Engineering for
DOS/Windows based PC's and UNIX systems.
Process simulation software for process design, optimization, troubleshooting,
debottlenecking, revamping or sensitivity analysis. Not related to BR&E's PROSIM. Site
requires Macromedia Flash Player.
Quick Hydraulics for Windows
Flowsheet simulation plus hydraulic pressure drop calculation for Windows 3.1 and higher
from Chempute Software. Lacks some of the features of other process simulators for the
benefit of lower cost. Restricted demo (2.7 MB) available.
Software Tools for
An independent list of process simulation tools from Aspen Plus to Supertarget. For each
program there are a short description, product specification, and user experience
Process simulation program for MS Windows 95, 98, ME, NT, and 2000 platforms from
Intelligen. Includes equipment sizing and costing. Demo can be downloaded and is fully
functional except for the ability to save the designs.
