FREE Process Simulation Software DOWNLOAD

You can have a process simulation software to practice process and plant design.

I do not have the numbers, but Aspen Hysys is probably the most known process simulation software for chemical engineering. In a poll I did in my Telegram Channel INPROCESS, 88% of people asked for more content about this software.

Different than Autodesk, find a commercial process simulation software for training is not an easy task. Most often, you need to go to Universities Labs, learn on the job (if your employer gives this chance to you) or spend some hundred dollars in training to get familiar with the process software.

Yes, I am considering only legal ways to have access to process simulation software. I don´t want to know about your cracked installation. Do not tell me about that.

In summary, commercial process simulation software is expensive (can cost more than 20,000 Usd/year) and with restrictive access as mentioned above. However they are very important in the plant design world because, if well understood and correctly used, they save a lot of time in the calculation of heat and material balance. Because of that, you save time in the development of engineering documents like process datasheets for instruments, equipment and so on.

SOFTWARE STRUCTURE

Although each company has its own design and interface, and some specific features focused in particular demand, the truth is that all process simulation uses the same principals to do chemical process engineering calculation. They need to have a consistent thermodynamic package and a reliable set of equations.

I am not saying that is easy to program this, I am just saying the way it works, and it is the same way you would do the calculation by hand. Remember that Our grandpa did not have computers and software to do plant design.

FREE OPTIONS

If you do not have a commercial process simulation software to practice I will give you two options.

The first one is DWSim, developed by Daniel Wagner. And the second one is Coco, developed by Jasper von Baten. Both software is free to download and use and very similar to Aspen Plus where you need to run your simulation to verify the results.

DWSim also has some exclusive features for Patrons, mobile options and so on, but in general terms, you can use it in your computer without extra content to get familiar with plant design.

As free software, its developers are not able to spend thousands or millions of dollars is the process simulation development. For that reason, it may not have a so easy interface or more complex options than other commercial software. But if you understand how they work you will short your curve of apprentice when learning another process simulation software.

I really encourage you to give them a chance. Start with simple tasks and known results to verify software consistencies and once you go further you can build a more complex process.

Below, you will find softwares description and link to download. Or you can download them from my INPROCESS mentoring channel in Telegram.

To download, click here (Windows Platform 64bit) or go to the website for more options.

DWSIM is a multiplatform, CAPE-OPEN compliant chemical process simulator for Windows, Linux, Android, macOS and iOS. Built on the top of the Microsoft .NET and Mono Platforms and featuring a rich Graphical User Interface (GUI), DWSIM allows chemical engineering students and chemical engineers to better understand the behavior of their chemical systems by using rigorous thermodynamic and unit operations’ models with no cost at all.

DWSIM has an easy-to-use graphical interface with many features previously available only in commercial simulators:

CAPE-OPEN features (Windows): Thermo 1.0/1.1 Property Package Socket, Thermo 1.1 Property Package Server, Unit Operation Socket and Flowsheet Monitoring Object support. Additionally, DWSIM exposes its Python Script (Custom) Unit Operation for all CAPE-OPEN compliant simulators.

FREE PROCESS SIMULATION: COCO

The description was taken from website

To download, click here (Windows Platform) or go to the website.

COCO (CAPE-OPEN to CAPE-OPEN) is a free-of-charge CAPE-OPEN compliant steady-state simulation environment consisting of the following components:

COFE – the CAPE-OPEN Flowsheet Environment is an intuitive graphical user interface to chemical flowsheeting.

COFE has sequential solution algorithm using automatic tear streams. COFE displays properties of streams, deals with unit-conversion and provides plotting facilities.

COFE flowsheets can be used as CAPE-OPEN unit operations; so you can use COFE Flowsheets as unit operation inside COFE (flowsheets in flowsheets) or inside other simulators.

TEA – COCO’s Thermodynamics for Engineering Applications, is based on the code of the thermodynamic library of ChemSep and includes a data bank of over 430 commonly used chemicals. The package exhibits more than 100 property calculation methods with their analytical or numerical derivatives.

COUSCOUS – the CAPE-OPEN Unit-operations Simple package is shipped with COCO. It contains a splitter, a mixer, heat exchangers, pumps and reactors amongst other unit operations. ChemSep-LITE, a limited version of ChemSep with a maximum of 40 compounds and 300 stages, can serve as an equilibrium distillation unit operation in COCO.

CORN – the CAPE-OPEN Reaction Numerics package that comes with COCO facilitates specifying any kind of kinetic or equilibrium reaction. Simple reactor units, like conversion reactors, CSTRs and plug flow reactors that can use the CORN package come with the COUSCOUS package.
