USIM PAC: process modeling and simulation software
Empower engineering decisions. Improve efficiency and profitability of your processing plant. Better, faster and safer.
USIM PAC is a steady-state process modeling and simulation software to design, analyze and optimize industrial processes. In a single interface, USIM PAC performs mass balancing, modeling and simulation of all the streams and unit operations of your processing plant. USIM PAC is a unique engineering software. It relies on a detailed and configurable characterization of material. Thus, it is particularly suitable if you deal with solids and complex mixtures, difficult to describe as pure substances.

Improve overall plant performance from lab to plant with our simulator
USIM PAC is a complete software platform for modeling and simulation of industrial processes.
It performs simulation, data reconciliation, mass balancing, flowsheeting, equipment sizing, economic and environmental calculations and off-line process optimization in a single environment for overall plant or part thereof.
USIM PAC relies on a unique approach to characterize solids and mixtures considering multi-component and multi-streams with phase changes.
Our process simulator has been originally designed for mineral processing and hydrometallurgy. It is the only software on the market able to model in one platform nearly all the mine-to-mill processing operations from crushing to refining passing through grinding, gravity and magnetic separation, flotation, leaching and concentration.

It ensures smooth scale up from lab to pilot and from pilot to plant. USIM PAC can also be very helpful for educational purpose or in the frame of R&D projects in process engineering.
An integrated simulator
USIM PAC is not only a tool to predict and optimize entire process plants. It allows to balance, model, simulate batch or continuous process in a single interface.
USIM PAC allows process engineers and scientists to:
- model plant operations using available experimental data
- determine optimal plant configuration that meets production targets
- size unit operations required to achieve given circuit objectives.
Equipment sizing & optimization
Capital cost estimation
USIM PAC is a process simulator used by engineers in more than 50 countries.
Better characterize materials to achieve accurate process design
A unique approach in material modeling
With USIM PAC, take into account the complexity and the variability of your materials: heterogeneity, components, composition, phases, phase transfer… Unlike most chemical process simulators, our process modeling and simulation software does not require the use of thermodynamic databases.
USIM PAC simulator is particularly suitable when processing raw materials, solids or solids and liquid mixtures, like ores, biomass, waste.
Combine all information into a single model
With USIM PAC, evaluate raw material, products, reagents, water, wastes… on a stream by stream basis for the entire plant.
USIM PAC also back-calculates data which cannot be measured.
Speed up process development and optimization
Built-in unit operations library
More than 150 unit operation models are available in order to complete daily tasks more quickly. USIM PAC includes models dedicated to various industrial fields such as comminution, physical separation, solid/liquid separation, membrane technologies, hydrometallurgy, biotechnology…
Mathematical models calculate the output streams data from the input streams data and model parameters. These parameters can be equipment sizes, operating settings and conditions, physical properties, model adjustment parameters or simply performance criteria.
