Process Simulation


Process simulation is the rigorous steady-state or dynamic mathematical modelling and visualization of continuously or discontinuously operated processes in terms of mass, energy, and information flows.

Process simulation has become an indispensible and strong tool for ensuring an optimal plant operation along the entire plant life cycle, including process development, optimization of plant performance, debottlenecking, revamp and so far.

Siemens EC has more than 30 years of experience in the field of process simulation and owns detailled expertise about up-to-date methodologies and Tools.

Besides modern process simulation systems being available at Siemens EC such as AspenPlus, the knowledge of process relevant parameters is essential for the model synthesis and analysis, e. g.

  • Physical properties of pure components and mixtures

  • Heat and mass transfer

  • Characteristics of the installed equipment and machinery

  • Chemical reaction kinetics

Siemens EC assists you in developing, running and optimizing the process simulation model:

  • Model development, choice of suitable methods (from short-cut to rigorous; from equilibrium to mass transfer model)

  • Determination of model parameters

  • Validation by comparison of simulation results with experimental or real plant data

A detailed rigorous process simulation model offers the following benefits:

  • Direct comparison of contemplable process options

  • Sensitivity analyses allow the identification of dependencies of relevant process parameters and their optimization

  • Prediction of effects of parameter changes

  • Energy optimization (Pinch Analysis)
