Process Simulation Cup 2019

START 15.02.2019 – END 17.01.2020

Congratulations – You’re hired!

It’s a pleasure to welcome you to your new workplace, the oleochemical plant.  As the new Shift Supervisor, you’re responsible for customizing oleic acid cuts.


As a Shift Supervisor, you must maximize the shift profit during a changeover.


The oleochemical plant is a two-step distillation plant. Due to the nature of the oleic acids, the operational conditions have to be adjusted frequently. The upcoming changeover must handle the change from optimized steady-state conditions for a heavy oil feed mixture which is cut to an intermediate heavy oil product mixture (high in cis-9-Octadecenoic acid) to the optimized steady-state conditions for a light oil feed mixture.

Current PSC Task Phase

Phase 4

Start: 15.09.2019

You successfully boosted the productivity of the plant. However, some problems with the reboiler remain.

The problem is a huge change in the bubble point temperature on the process side of the reboiler caused by the changing feed composition.

You recommended changing the utility used in the reboiler from steam to latent heat fluid. (Therminol 66TM meets the requirements).

Upon your recommendation, the utility system has been replaced and the plant can be operated much smoother. The price of the light oleochemical intermediate that you produce has increased. However, you must now pay for the consumed hot utility.

The product can be sold for 2 $ per kg, while 0.01 $ must be paid per utilized kg of Therminol 66TM .

The heat transfer coefficients in the reboilers changed and some valves had to be replaced. The PID parameters of the pressure controllers have been tuned. The variables and bounds remain unchanged (see Phase 3).

Now, it’s your job to increase the shift profit even further!


Below are documents that will help you kick-start PSC2019:



Note: PSC challenge consists of several task phases that are progressively rolled out throughout the year. We also progressively unlock design variables which are currently displayed as inactive on the submission form. We might manipulate some data too. Time and date of the above are not defined in advance. To be up to date with changes and not to miss out on developments, stay tuned into the PSC newsletters, social media, news, and our blog!


Why you should take part in PSC?

It’s fun, it’s real, it educates. When working on the PSC solutions, you deep dive into a problem and expand not only critical but also lateral thinking skills. You showcase your drive and commitment. You might even discover that you’re great at something outside your comfort zone! No doubt, young well-trained professionals stand out. PSC will help you to develop a competitive edge and land a dream job in the future. Let your personal and professional goals guide you when walking the PSC award path! And PSC is open to participants from around the world all year long!

What Are Your Awards?

The  Champion

You collect PSC Cups for submitting solutions. If your solutions are better than others and you move up the highscore table ranks – You earn cups! In addition, you have a unique “My PSC referral link”. If your friends register via your link and submit variables, you will get PSC Cups too! Are your friends making headway in our Hall of Fame? Great! You earn cups as long as your PSC fellows make progress.

At the end of the challenge, a PSC student participant with the highest cups total wins certified *CHEMCAD Training! Wouldn’t it be awesome to learn CHEMCAD together with the industry practitioners? Of course, it would!

*CHEMCAD Training is currently offered to students in Europe and the USA, for details visit FAQs.

Monthly & Overall Winner

  • You rank first in the Hall of Fame at the end of the month,  you receive a Certificate, 100 PSC Cups, and Amazon Voucher worth €25.
  • At the end of the challenge, 3 participants with the best results achieved in the final PSC Phase will be awarded one of our 3 Overall Winner titles, get certificates and Amazon Vouchers worth €200, €150, €100 and more!

*International participants receive Amazon vouchers in the currency of their respective countries (as long as it’s applicable)

PSC Student Ambassador

It works exactly in the same way as in the case of the PSC Cups Champion. The only exception is that you make it a mission for yourself. You put your creative ideas into action to spread the PSC word to others!

At the end of the challenge, a person whose “My PSC referral link” has been shared most times will be awarded the PSC Student Ambassador title, will be featured on our Team page and will receive Amazon Voucher worth €80! You can learn more about the awards visiting our PSC Ambassador page. Please note: every referred friend must submit variables to PSC at least once!
