Process Optimization

By means of process optimization we reveal saving potentials for our customers processes, focusing on increased energy and resource efficiency.
Throughout the simulation, different options for heat recovery, process combinations and/or process strategies can be examined and evaluated.


  • Lower fixed and variable costs
  • Higher energy and resource efficiency
  • Decreased carbon emissions
  • Increased purities, yields and  process flexibility

How it works

Process optimization ensures the maximization/minimization of one or multiple variables while acknowledging the natural constraints of a process. 
For that purpose PrimeUnit applies optimization algorithms already implemented in CHEMCAD as well as custom programmed optimization tools. 
Usually a simulation is first enhanced by simple sensitivity studies and engineering techniques (pinch point analysis, etc.). 
Optimization resembles a much more detailed approach, resulting in optimal process performance though usually to the expense of increased mathematical complexity.

Exemplary Workflow:

  • Prior to the exchange of confidential data a Non-Disclosure agreement (NDA) is being issued between the client and PrimeUnit if requested.
  • After that, the client provides all available data regarding the process (P&ID, old process documentation, measured data, existing simulation data, etc.) and PrimeUnit will generate a process simulation strategy incorporating existing models and/or custom models.
  • In case of missing thermodynamic data, PrimeUnit will examine the availability via subcontractors in case the client is not able to provide additional data sets.
  • Once a rigorous model is set up it is continuously improved and validated through the client’s process data until an acceptable deviation is reached.
  • PrimeUnit will then use the validated model to obtain superior performance results, thus minimizing energy and resource demand and/or maximizing yield.
  • Finally the results are displayed through an in-house presentation of the process optimization and the project is completed by the delivery of a detailed documentation as well as the simulation files.
