gPROMS platform is a feature-rich environment that brings many major advantages over other comparable modelling software. gPROMS family products benefit from the following: support for multiscale modelling, meaning – for example – that it is possible to create a reactor model that takes into account all phenomena from mass transfer in the catalyst pore to full-scale equipment effects simultaneously custom modelling capabilities that allow the development, execution and maintenance of high-fidelity models of a wide range of equipment the abilty to apply such high-fidelity unit models within a full process flowsheet estimation of equipment or process empirical parameters from experimental – laboratory, pilot or operational – data, with estimates of data uncertainty for risk analysis steady-state and dynamic modelling within the same environment the ability to perform many different activities using the same underlying model support for scale-up from minimal experimental data to full equipment, using hybrid modelling technologies where necessary.
