About ProSim

Chemical Process Simulation Company- EXPERT IN PROCESS SIMULATION SINCE 1989 -

During the entire decade of the 1970's, Professors Bernard Koehret and Xavier Joulia and their team from the renowned INPT-ENSIGC's chemical engineering research center created and developed a flowsheeting software based on a new approach. In 1989, to respond to the interest shown by industrial groups, they decided to enhance the value of their work in process modeling and optimization by creating ProSim.

ProSim 's CEO is Stéphane Déchelotte.

ProSim remains an independent company, which is headquartered in Labège (Toulouse - France) and has an office in Philadelphia, PA in the United States.

ProSim provides worldwide process industries with state of the art simulation and optimization software to improve process design, increase plant efficiency or reduce impact on the environment. The success of the company comes not only from the efficiency, the robustness or the openness of the proposed software, but also from the quality of the associated services provided.


Chemical engineering software

Thanks to long term partnerships with major research centers and to substantial investment in R&D, ProSim continuously develops innovative software and offers a complete suite of software:

  • Powerful and easy-to-use steady-state process simulator with efficient convergence methods.
  • Widely validated physical property models and comprehensive thermodynamic package.
  • Unique solutions tailored to specific domains: nitric acid production, batch distillation columns and chemical reactors modeling, plate-fin heat exchangers, process energy integration (pinch technology) …


Tailored services

With a customized approach to all requests, flexible licensing policies for small and big projects, high quality engineering services, ProSim brings simulation and optimization responses that are adapted to your industrial needs.

  • Process studies through modeling and simulation, energy audits…
  • Application implementation and software extension, on-site technical assistance…
  • Specific software applications development, support and maintenance of "legacy" codes.


Maintenance, support & training courses

Experience, know-how and reactivity of ProSim engineers guides you to fully use the potential of the software.

  • Support and maintenance: advice on thermodynamic models selection, research of missing data, solution to process issues, help with convergence of complex flowsheets…
  • Training: standard training courses included in maintenance agreements, or on-demand/on-site customized process simulation training courses to go further with the software.
