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 task phase

Phase 3

PSC2019 for ECCE12 & ECAB5 task phase will be launched on 15.09.2019

Start: 17.06.2019

You did an amazing job and the profit of the change over shifts was increased by more than a factor of two! And now, due to increasing demand for biofuels, the market price of your plant’s product has also increased by a factor of two, from 0.5 $ per kg to 1.0 $ per kg. This makes a good changeover shift even more important.

But there are still some problems with the reboiler due to sudden changes in the set points. To avoid that, you can now enter smoother profiles by adjusting one additional ramp point per operation parameter. This leads to a total of 17 decision variables.

For the decision variables some bounds exist:

  • the switch time and the intermediated ramp times can be variated between 30 minutes and 480 minutes after the initiation of the changeover
  • the intermediate ramp points for the set points for the reflux ratios can be variated between 0.1 and 40 and between 0.1 MW and 5 MW for the reboiler duties
  • the second ramp points of an operation parameter must occur after the first ones

It’s a new opportunity for you to demonstrate your engineering skills!

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!

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