ExploreFrequently asked questions
What is process simulation software?
Process simulation software models the mass and energy balances, phase equilibria and unit operations of a chemical process so engineers can design, debug and optimize a plant on a computer instead of in the field. MaximaLabs does this in your browser, with rigorous thermodynamics and an AI copilot, at usage-based pricing instead of six-figure seat licenses.
What is the difference between steady-state and dynamic process simulation?
A steady-state simulation solves the plant at a single fixed operating point (the design case); a dynamic simulation adds time, so you can study start-up, shutdown, upsets and control. MaximaLabs runs the same flowsheet in steady-state, pressure-driven and dynamic modes — no re-authoring between them.
Do I need to install anything?
No. MaximaLabs is a browser-based process simulator — zero install, nothing to license on a workstation. You can also drive it from a Python SDK or an Excel add-in.
Which thermodynamic methods and unit operations are supported?
The major property packages (Peng-Robinson, SRK, NRTL, UNIQUAC, PC-SAFT, electrolyte-NRTL, GERG-2008, steam/IAPWS and more) and 60+ unit operations — distillation, absorption, heat exchange, reactors, crystallizers, electrolyzers and beyond. Browse them under Property Packages and Unit Operations.
