Simulation is using computer-based modeling of a system to understand its behavior and predict the effects of changes. It’s a powerful method for analyzing, designing, and operating complex systems. It provides an inexpensive way to explore new processes and designs, without having to resort to costly lab or pilot programs. It is also a fabulous way to improve the understanding of phenomena.

The basic idea of process simulation is to represent the behavior of a real-world physical process in a replicable, mathematical model. Our process simulation software imitates the process of interest by configuring pre-built unit operation modules (sequential modular flowsheeting environment). Since the material flows undergo transformations in the unit operation modules which modify their physical or chemical state, our high-fidelity simulation environments include comprehensive thermodynamic model libraries and physical property databases. These allow users to identify the physical and chemical characteristics of the process material from feedstock through each phase of the process. The quality and the diversity of the thermodynamic models available is a key point.

Our steady-state process simulators, as the name implies, provide details of a manufacturing process under one specific set of operating conditions. These simulation models can be run multiple times to develop cases for different operating ranges.

• They are irreplaceable tools for performing process analysis and design to determine the requirements of a system (feedstock, energy…).
• They offer a safe, reliable, and cost-effective means to test the capabilities of a system and perform what-if analysis for configuring processes and evaluating new equipment.
• They help users understand how their plant operates to aid in process improvements, debottlenecking, troubleshooting, and performance monitoring.
• They allow exploring regions outside the known operating ranges of the process.

Dynamic simulation or simulation of batch unit operations, in contrast, predicts how process variables change with time when moving from one steady-state condition to another one or during the batch operation. In other words, during a transient upset, dynamic simulation would track the values of variables over the transition period, while steady-state simulation would provide only the values of the variables at one state.

When making use of the optimization capabilities of our process simulation software, some of the degrees of freedom are left unspecified. The values of the corresponding variables are determined by an algorithm that will minimize an objective function specified by the user, while respecting physical, operational, safety, product quality, contractual, or any other constraints. The objective function is usually an economic variable such as net operating cost.

Using process simulation and optimization, companies have drastically improved operating efficiencies. They can now reduce their carbon footprint, become more energy efficient and make the best use of available resources.
