About ProSim

Process Simulation Company


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.


The company provides state of the art simulation and optimization software that allows process industries to increase their efficiency and their return on investment. ProSim solutions are designed for applications in the chemical,  refining, gas treatment and specialties chemical industries, in addition to  in the pharmaceutical, food processing and energy industries.
