How does APM relate to other modelling and simulation technologies?
A gPROMS APM is typically a first-principles model that embodies fundamental chemical engineering, physics and chemistry relationships, validated against observed data. This gives it a higher level of predictive accuracy and wider range of application than any other type of model currently in widespread use. APM differs from the traditional technologies available to the process industries, such as process simulation and Computational Fluid Dynamics (CFD), in: • its degree of predictive accuracy for complex chemical phenomena • the range of application (from micro- to macro-scale) of models • the extent to which it can be applied across the process lifecycle, from laboratory analysis through process engineering to online operation. APM is, however, entirely complementary to existing technologies, and can augment their application significantly. For example, a high-accuracy reactor or distillation model can be deployed within a traditional process flowsheet simulator, in order to investi
