USIM PAC


Process simulation software package


USIM PAC enables to model and simulate in a single tool the whole industrial transformation raw materials. USIM PAC facilitates:
  • Mass, energy, water and CO2 balances
  • Industrial process audit
  • Plant optimisation or comparison of scenarios
  • Technical and economic feasibility studies

Thanks to its modular structure, USIM PAC includes various libraries of unit operation models dedicated to the following industrial fields:

USIM PAC for mineral processing

USIM PAC for food processing & biorefining

USIM PAC for waste & wastewater treatment

USIM PAC improves efficiency during process design, plant sizing, plant survey, process optimisation.

USIM PAC can also be very helpful for educational purpose or in the frame of R&D projects in process engineering.
