Aspen Plus/HYSYS

Aspen Plus and HYSYS are the dominant chemical-process simulation platforms — used in battery production to model electrolyte mixing, solvent recovery distillation, cathode-material precursor synthesis, and the thermal balances around dry-room HVAC. As a hard skill it requires fluency in flowsheet construction, unit-operation parameterization (reactors, columns, heat exchangers), thermodynamic property method selection, and the discipline to validate simulated results against bench or pilot data. Process engineers apply it when scaling up an NMC cathode precursor process, when designing the solvent-recovery train on an electrode-coating line, or when modeling the thermal performance of a dry-room desiccant loop.
