Dear Pedro,

For mixture you can estimate individual molar volumes for pure components

Then you can estimate by simple arthematic average based on thier mole
fraction.

or

apply various mixing rules

Rao

Hello Pedro!

Calculation and Shortcut Deskbook which comes free with the
subscription
from Chemical Engineering Magazine discusses an equation that estimates
density of pure n-alkanes basing only on the number of carbon atoms and
the temperature. This is according to Charles H. Fisher:

d(C+1.215) = -0.29796 +  0.86555C - (0.0025302+0.00057592C)t

where d = density relative to water at 4 deg. celsius
       C=  number of carbon atoms
       t = temperature in deg. celsius

See the article: "How to Predict n-Alkane Densities" from the book for
more details. My guess is this is also found in CE archive.

I hope this helps.

Greetings!

This is in response to a query posted by J.J. Hiluy Filho.
The message is quoted below.

Kindly see the website of Gensym at this address:

http://www.gensym.com

I believe they have list of products in there including G2.
You can ask for additional information or request for a
demo copy.

Thanks a lot.

Just a few doubts:

In step 1, for mixtures, should I find the boiling
point performing some LVE (liquid-vapor equilibrium)
calculations? and can I use a pseudo-critical
temperature for a mixture of compounds?

Thanks again.

Dear Allan,

Thanks. I had recieved a lot mails from you.

What I specifically look for is either HETP values for various structured &
Random Packings.

If you have any idea about Stichmer Constants, you can even send them for
various packings.

With Thanks & Regards,
Rao

Dear Neil,

Thanks. I found in literature that for pilot plants of small diameter this
rule holds good.

I am looking for commercial columns with Random as well as structured
packing

Rao,

May I invite you and other members to visit this site:

http://www.vff.de/englisch/software_e.htm

It contains a Packing Software which is available as a
freeware.

A glimpse of the page:

"Hydraulic calculations with approx. 60 different packing
types (pressure drop, flooding point, hold-up, colomn
diameter).

Universal mass transfer calculations (NTU, theoretical stages,
HTU values, HETP values, diffusion coeffizient, etc.)."


I hope it will help you and the rest.

But I do not find any numerical values or thumb rules in calculating HETP

Hello there!

What I can suggest is for your to visit the
Chemical Engineering Magazine Archives:

    http://archive.che.com

Then, search for HETP.  There are a lot of
related articles there.  One example is
"Practical Tips on Tower Packing".

I will send you a "copied" version of the
article which I got from their website should
you have no web access.

The rest of the members of the group are also invited check
the page.


There is also a book entitled, "Rules of Thumb for Chemical
Engineers." which you may find very helpful. Go to amazon.com

The easiest way to do this is to use the correlation in Hydrocarbon
Processing, March, 1980, page 115.

The correlation is density (g/cm^3) = 0.982554 x (normal boiling
point in degrees Rankine)^0.002016 x (specific gravity at 60 degrees
F)^1.0055.

The maximum deviation is reported to be 1 percent.

Hope this helps.

symbolic, numerical, and graphical operations extremely well! Also has a
tool called Control System Professional that makes Mathematica very

Hello Dr Leon,

In my institution, for all scientific computation, the norm was to use MATLAB.
It was extensively used for process simulation, iterative process design,
process optimization and model identification; apart from process control.

MATLAB was not taught in any course, but students used to learn it on their own
with the help of manuals and online help. MATLAB scripting is quite easy to
grasp for anybody having exposure to programming.

MATLAB is fantastic in its numerical capabilities, especially the ease of matrix
computations. It also gives powerful plotting features (2D and 3D). The already
rich library is extensible. It can also be interfaced with C or FORTRAN
programs.

The only shortcoming of MATLAB is its inability to support symbolic computation
directly. However, there are libraries which work with polynomial functions by
expressing the polynomial as a vector of its coefficients. MATLAB also does not
support higher order tensors, if ever their need arises.

Hope this helps,

-Ashish

Dear list members,

Presently Polymath and MATLAB  are the computer
algebra systems we use at our faculty:
In undergraduate teaching Polymath is being used in
many subjects. MATLAB is used only in process control
course, but we plan to use it more intensively.

I would like to know experiences related to the use of
MATLAB in Chemical Engineering teaching:
* In what courses it is used?
* What kind of problems it is used for?
* Which are its advantages and disadvantages in
comparison to other systems?

Thank you very much in advance.

Sincerely,

Dr. Osvaldo Goza Leon
Faculty of Chemical Engineering, ISPJAE

As a practicing chemical engineer, I recommend the following minimum
software knowledge for all chemical engineering students:

As Freshmen:
Windows OS
Microsoft Word
Microsoft Excel
Microsoft Powerpoint
Introduction to Mathcad

Further Years:
Build on Excel and Mathcad talent.

Pick one programming language such as VB or Fortran.

Other software can be selected to match courses as needed such as
Matlab for controls and a process simulator for the design class.

Hello:

         In spite of belonging to the Antibiotic Department, I am a lecturer
at Chemical Engineering Department graduation course. My duty is to teach
the discipline "Computer in the Chemical Engineering" (Computação na
Engenharia Química). The discipline starts with computer architecture
including up to date description of the computer pieces. Since this is a
fast changing area I avoid the use of books directing the students to
computers magazines and journal or Internet sites. I consider this very
important because chemical engineers have to give correct and up to data
specifications of their computational needs. After that I cover the
operational systems emphasizing Windows and Linux. Then I go to the soft
wares used by chemical engineers. I know that most of the engineer time is
expended in preparing memo and documents, presentations and graphics which
require the use of a suite like the MS Office, StarOffice or Wordperfect.
Computational algebra is also an important subject and a general view is
presented to help the student to select the most suitable software (MathCad,
Mathematica, Matlab, Maple and so on). A short view in general methods of
equipment and processes modeling follows that. Then a review of the
numerical methods (there is a discipline in the course which is directed to
theses methods) and a general view of programming language emphasizing Java
and C++. Nevertheless, I accept the use of any programming language in the
discipline home works. Most of the student  prefer Pascal which is thought
as preferential language at our university, nevertheless there is a lot of
pressure toward Fortran by other chemical engineering lecturer as usual. In
spite of this, very few students select the Fortran as their preferential
language. Students which use C++ or Visual Basic are very rare. The few ones
I found in my discipline revealed to be programmer. Training the student in
the use of Internet and to prepare HTML hypertext is also a subject of this
discipline. Unfortunately, no CAD and CAM  softwares are considered at level
required by the profession.

Hello everyone!

Let me start the discussion.  I believe some of us are interested
to know what some universities are doing with regards to preparing
their students in the use of chemical engineering softwares which
they will most likely be using in their future careers.

I wish to know and I think some of us also wish to know, the exact
description of courses that are directly related to Computer
Applications in Chemical Engineering in your universities. The course
title maybe a little
bit different.

My purpose is for us to have some starting point on the background of
students taking up chemical engineering. I believe those who are in
the academe can best answer this.

What the people in the industry can do maybe is to verify the
use of these softwares in the actual job experience. Are these
softwares actually used? And perhaps we can reach an answer to this
question, "Are we adequately preparing our chemical engineering
students
in their future challenges specifically in the use of chemical
engineering softwares in their future jobs?"

Thank you very much for your answers.

Sincerely,

Allan

Greetings Everyone!

Wow! I never expected that this list would grow this fast!
To all of you who responded to my invitation, welcome!

I made some changes with the group guidelines due to some suggestions
from some members. The group discussion is now divided into four
major discussions: process simulation softwares, computer algebra systems,
numerical systems, and computer programming (not just C).

The reason why we have to do this classification is for organization and
focus. But let this not divide the group. Remember, there is no subgroup
in che-comp.

Suggestions are always welcome. If you have something to add, delete,
or anything to say that will benefit the group, please do so.

For more information kindly check out again this page:
http://pages.whowhere.com/computers/consul

and read the che-comp Group Guidelines.

Like what I have said in the previous email, I regard this mailing
list as an organization and I hope you do the same way. :)

Feel free to discuss.

Sincerely,

Allan S. Hugo
List owner
