BDSIM Binary Distillation Simulator
Binary distillation software generates graphic McCabe -Thiele diagrams, composition profiles, Xlk/Xhk ratio profiles and Lambda function profiles. Performs NTS, Column diameter and HETP calculations for any set of feed and product compositions, R/Rmin and relative volatily of components to be separated. Free demo version is available for download upon password request.
Bryan Research & Engineering Prosim
General process simulator for design and optimization of plants in the oil, gas, chemical, and refining industries. Restricted demos available.
Chemical Engineering MathCAD Users' Group
Web site for MathCAD users to share worksheets that perform calculations useful in Chemical Engineering design and analysis. The programs contributed to this site are freely accessible to the public for personal use.
Chemical Process Modeling PC Software
Excel add-ins, Mathcad and Maple files for chemical plant modeling, distillation design calculations, pinch analysis... The software is copyrighted but free for personal or educational use.
DESIGN II for Windows
A process simulator developed specifically for MS Windows (either Win 95/NT or Win 3.1/3.11 with Win32s). The full package of version 3.2 (no demo) is available free for download but you must register to get a 2 week password.
Hyprotech HYSIM Process Simulator
Steady state process simulator for the PC. Incorporates a wide range of unit operations, heat exchanger design, compressors, valves, and extensive thermophysical property data.
Hyprotech HYSYS Dynamic Process Modeling
Flowsheet based dynamic process modeling for MS Windows 32 bit platforms. Steady state modeling is integrated.
Membrane Process Modelling Software
Several programs for membrane modelling and related fields. Software is distributed free of charge but may not be used for commercial purposes. This site is in South Africa which explains the sometimes low transfer rates.
Process Tools
A huge collection of online process engineering tools provided by Process Associates of America.
Prode Calculator
Tool for solving problems in chemical engineering on the PC. Free preview version can be downloaded.
Software Tools for Process Integration
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 evaluations.
SuperPro Designer Demo
Process simulation program for Win 3.11/95/(NT). Includes equipment sizing and costing. Demo (total 8 MB) is fully functional except for the ability to save the designs. Demo user registration is optional.
