Process simulation with SIMIT CHEM BASIC library and SIMATIC PCS 7

  • Entry
  • Associated product(s)
The FLOWNET and CHEM-BASIC libraries are expansions of SIMIT. The libraries provide component types that enable you to simulate pipeline networks in the chemical and pharmaceutical industries in particular.

Interconnecting the library components enables a model of a flow network to be generated in SIMIT, which plausibly simulates the thermodynamic processes in pipeline networks. You can create flow networks for different media, e.g. water / steam, liquids or ideal gases.
The present application example uses the example of a stirred tank reactor to show you how to use the library components of CHEM-BASIC to create a corresponding simulation model.


  • The CHEM BASIC library provides a quick introduction into the SIMIT project planning
  • Communication of the necessary knowledge to develop simulations
  • Reduction of effort needed for configuration thanks to the use of library components


  • SIMIT Simulation V9.0 SP1
  • SIMATIC PCS 7 V8.2
