Experienced-Based Rules in
Chemical Engineering. This article, which comes from the Cheresources.com
website, summarizes many "rules of thumb" in the area of chemical process design,
including the design of separation processes. It is a summary of the contents of
the textbooks on this subject by S. M. Walas, Richard Turton, Carl R. Branan, and
Christopher Haslego. The
content of this article is also available in a very handy Excel spreadsheet which
you can obtain

Databases and Libraries:
CheResources.com This is a link to the Separation Technologies portion of the
process design articles part of the Chemical Engineers Resource Page website. You
can scroll up and down to see other useful process design articles.
NIST Chemistry WebBook. This useful database
contains thermodynamic properties for over 7000 organic and inorganic species.
Useful Free Software:
ChemSep-LITE. This free version of
ChemSep, called ChemSep-LITE, simulates multicomponent distillation, absorption, stripping,
liquid-liquid extraction, and single-stage flash processes and was developed by
Ross Taylor at Clarkson University and Harry Kooijman at Shell Global Solutions International.
Be sure to also look at the rest of the ChemSep website, which contains lots of interesting
information. ChemSep is a CAPE-OPEN (Computer
Aided Process Engineering Open Source) compliant software program and is part of the COCO (CAPE OPEN to CAPE OPEN)
suite of free software described in the next link.
COCO. COCO (CAPE OPEN to CAPE OPEN) is
a suite of free computer aided process engineering software programs that includes COFE (CAPE OPEN
Flowsheet Enviroment), CORN (CAPE OPEN Reaction Numerics), ChemSep as
described in the previous link, and many other components. For maximum software stability, you should uninstall any previous versions
of ChemSep on your computer before you install COCO so you have only one copy of ChemSep on
your computer. COCO is an example of the newest generation of software for computer
aided process engineering which consists of "plug and play" components that are largely free.
Octave. An open-source free MATLAB
clone originally developed at the University of Wisconsin
Julia. An open-source free programming
language developed at MIT for high-performance computing and machine learning applications. See the additional
information on this language in the Tutorials Section.
WAVE This software for the design of water treatment systems including ion-exchange processes was developed by DOW.
Swing Adsorption Calculator. This software for designing pressure swing adsorption processes
was developed by James Ritter at the University of South Carolina.
Simulation of Multicomponent Distillation.
An Excel spreadsheet developed by Douglas Frey at UMBC which
simulates the time-dependent approach to steady state of a multicomponent
distillation column when the plate compositions are initially set at arbitrary
values. This software also provides a convenient way to solve the multicomponent steady-state
"operating problem" by simulating the approach to steady state.
Separation Processes, 2nd ed. This is the link to the free on-line version of the
classic book on separation processes by C. Judson King. The paperback version of this textbook is published
by Dover and is well worth purchasing as a low-cost supplementary textbook in a separation
processes course. It is available from Amazon and similar sites.
Books for Fun:
The Art of Distillation. This book is a little old. Actually, it
was originally published in the year 1651 by the alchemist John French.
Home Distillation Handbook. For the home hobbyist. But be
careful, the procedures described in this book are illegal to do in the U.S.
