We have flowsheeting software (PSE software) as well as powerful digital development tools, in order to offer you software solutions that meet your needs as closely as possible.

In order to design more efficient units, operate a highly integrated process as close as possible to its limits, and deal with new regulations (environment, safety, etc.), engineers can no longer content themselves with simple process models. They need a powerful but also easy-to-use tool to simulate plant behavior, quickly test new configurations and obtain an optimal solution without being modeling specialists.

Flowsheeting software (or PSE, such as the AspenTech® or ProSimPlus® software suite) meets these requirements by offering a complete, user-friendly, technically complete, numerically stable environment and ensuring compliance with material and energy balances. The use of these digital tools makes it possible to model any type of material transformation process and thus allow industries to improve their operational efficiency, reduce their carbon footprint, become more energy efficient and make the most of resources available.

We have developed three numerical tools to model multi-constituent separation of a gas mixture through a membrane module.

All these tools are compatible with most flowsheeting software (PSE software) such as AspenPlus®, Hysys®, Pro/II® (AVEVA®), GPROMS®, PROSIM®, COFE, etc.

Module for simulating multi-constituent mixture separation by gas permeation


Module V1 supplemented by the following specificities:

  • Upstream and downstream pressure drop taken into account
  • Joule-Thomson effect: taking into account heat losses due to the pressure drop between membrane upstream and downstream sides
  • Database of characteristics of commercial membranes
