New challenges and opportunities for process modelling

Publisher Summary Process modeling has made substantial progress over the past decade. This chapter discusses the three of the major issues in process modeling that need to be addressed for this kind of progress to be sustained over the next decade. These are the modeling of complex distributed systems, the construction of validated models, and multiscale modeling. The chapter is primarily concerned with process modeling methodology. Naturally, substantial improvements in physical understanding continue to be a major requirement in several areas of importance to process engineering. The construction of validated process models, in a satisfactory manner will require the solution of several novel types of optimization problem beyond those that have already been widely recognized. Some of these new problems require significant developments in global optimization techniques, especially for the solution of time-dependent problems. Multiscale modeling is a key to the effective utilization of computational chemistry techniques for process modeling applications. Multiscale modeling is still in its infancy as far as general systematic methodologies are concerned.
