Process simulation

Chemical process simulation, or process modelling as it is often referred to as, is a computer modelling technique used in process design. It allows engineers to predict the steady state or dynamic behaviour of a system by using computer software to create a system of interconnected unit operations, which are then evaluated as a fully operational plan. Using chemical process simulation can bring huge benefits in terms of safety, cost effectiveness and efficiency, particularly when used during the concept and front end design stages of a project.

We have unrivalled knowledge and depth of experience in chemical, physical and thermodynamic properties of the materials processed and also the characteristics of the process equipment items typically employed, for example reactors, columns, mixers, membranes, dryers, pumps and heat exchangers.

We can apply process modelling and computer simulation techniques to predict steady-state or dynamic behaviour. We do this using a range
of software tools, including AspenONE®. Once the required process components and connections are established, process flow diagrams can be
used to represent the resulting model(s). Our software tools can help with many requirements, including:

  • Design of individual and interconnected unit operations
  • Process optimisation including capacity, performance, operating costs and utility consumption
  • Batch operation scheduling
  • De-bottlenecking of existing facilities
  • Gas dispersion modelling
  • DIERS software for relief device sizing (two phase modelling)
  • Hydraulic modelling of clean water systems
  • Heat transfer software to model vessel heating and sterilisation performance
  • Waste stream characterisation
  • Environmental impact assessments
