gPROMS ProcessBuilder: Equation-Oriented Simulation for Advanced Process Optimization and Parameter Estimation

gPROMS ProcessBuilder by Process Systems Enterprise employs an equation-oriented architecture that solves all process model equations simultaneously, enabling rigorous parameter estimation from plant data, dynamic optimization, and reliable convergence of tightly integrated flowsheets. This article explores how its EO solver, built-in maximum likelihood parameter estimation, and simultaneous collocation dynamic optimizer differentiate it from sequential-modular tools like Aspen Plus and HYSYS. Engineers working on reactive distillation, batch optimization, or kinetic model fitting will find gPROMS ProcessBuilder's capabilities particularly compelling.
