Process Simulation Essentials for 
Undergraduate Education
Attend our exhibitor workshop at the 2015 AIChE Annual Meeting 


Calling all Chemical Engineering academics!
Chemstations, Inc.
Are you or your colleagues attending the 2015 AIChE Annual Meeting in Salt Lake City this November? If so, you won't want to miss out on Chemstations' exhibitor workshop called Process Simulation Essentials for Undergraduate Education.

Professors in Chemical Engineering departments worldwide have communicated to us for many years that they want to teach "engineering" and not "process simulator usage." Students need to understand the tools they will use in industry, and have an interest in a well-rounded resume/CV. So in response, we've put together a library of materials suitable for use in academic curricula.
Chemstations would like to invite professors, students, and all other interested parties to learn more about our new Process Simulation Essentials for Undergraduate Education program. We will present a half-hour overview (repeated three times during the session period) of the materials available to professors and students, including example simulations, recorded videos, presentation slide decks, and even a worldwide student competition. Between our formal presentations, Chemstations staff will be available to answer questions and go into more detail on all of the available resources.

  • Focus your time on developing course material instead of teaching simulator use
  • Get students up to speed on simulation tool faster
  • Expand students' real-world skills and interaction with global network
There is no cost to attend for AIChE Annual Meeting registrants. The overviews will be presented at
12:45 PM, 1:30 PM, and 2:15 PM. Come by for a presentation, learn about the available resources,
and chat with other educators and our staff.

Please spread the word by forwarding this message to any Chemical Engineering professors or students who may be attending the Annual Meeting. For questions, or to learn more (especially those not attending), please contact Jill Eastwood at

Did you know CHEMCAD can be used for environmental point-source emission calculations?

At some point in the design or operation of chemical processes, you may need to satisfy regulatory compliance by doing emission calculations. Rather than use separate (possibly non-rigorous) tools, we’d encourage you to use the CHEMCAD models you may have already built for your processes.
Our good friend, Dr. Jeff Silverstein, has written a thoroughly-referenced paper that walks through two examples of charging empty vessels based on the US EPA’s publication: Methods for Estimating Air Emissions from Chemical Manufacturing from Volume II: Chapter 16 of its Emission Inventory Improvement Program (EIIP).
Click here to download the paper, and here to download the CHEMCAD example simulation files referenced in the paper.

Please have a look to see if you can take advantage of his long experience in the field to speed up and improve your environmental compliance calculations. We, and Dr. Silverstein, welcome your feedback for potential future papers in this area.

Did you know that CHEMCAD can calculate flow rate as a function of pressure?

How do you approach engineering challenges involving hydraulic balance in piping networks? The right tools are essential when designing and evaluating a flare network or relief piping system, calculating flow and pressure drop through equipment, or diagnosing leak problems in plants.

CHEMCAD can help with these challenges, by performing hydraulic balance and pressure calculations in piping networks. The program predicts pressure drop, flow rate as a function of pressure, choked flow, and backflow; for more complex systems, the program also calculates pressures and flow distribution through different branches in pipelines based on pressure balance.

If enough variables are specified in the simulation, CHEMCAD can simultaneously calculate the unknown pressures and/or flow rates throughout the model.
CHEMCAD also leads users to specify the geometry in pumps, valves, compressors, and fittings, and hydraulic resistances in pipes, to enable estimation of the pressure balance as a function of the known variables.

The back pressure on valves, pipes, and pumps affects pipelines’ upstream and downstream conditions. Reverse flow can damage equipment, contaminate fluids, and present a serious risk to health and safety. CHEMCAD can predict flow direction, backflow, or reverse flow by simultaneously solving the pressure balance throughout the entire piping network; it also calculates the flow that pumps and compressors can handle using inlet pressures, outlet pressures, and performance curves.

If you’re ready to start setting up piping networks in CHEMCAD, contact your sales or support representative for more information.
