However, during the conceptual design and operational stage of these infrastructure systems, not enough parameter information (e.g. from historical database etc) may be available for a realistic availability and cost estimation. To circumvent this, we propose in this paper, an adaptive control approach.

Therefore, hydrogen system is bottlenecked and hence hydrogen management has become a priority issue in current refinery operations.

The approach presented by Tousain and Meeuse (2001) is extended to include the robustness properties in terms of two different uncertainty models: parametric uncertainty and co-prime factor uncertainty. The simulation results on a distillation column demonstrate that the optimal design parameters using the nominal closed-loop controllability will not alter after introducing the robustness criterion.

The values of the design variables are determined so that an economic criterion is optimised subject to the modelling equations of the process and a set of safety, operating and product quality specifications. The distillation column is divided into different sections to account for reactive and non-reactive parts of the column. The design variables include the number of stages in the different column sections, the location of the feed streams, the column tray liquid phase holdup for each column section for homogeneous liquid phase reactions, or the catalyst load per tray for catalytic reactions, and the optimal operating conditions. An equilibrium stage model based on the MESH equations is utilised with kinetically controlled chemical reactions. The economic objective function consists of the annualised investment capital costs for the design and the operating costs for the column.

The place of systematic design frameworks in such design procedures has been recognized and consequently resulted into developments of systematic, hierarchical and multi-space design frameworks. However, it is observed that not much is known in the process design domains, of a systematic way of testing and validating such hierarchical multi-space design methods for the intended class of users. In this work a generic approach for the testing and validation of such novel design framework is being expounded. The study integrates the Analytical Hierarchy Process (AHP) and the Fuzzy Expert System (FES) to establish a concept for scientifically and quantitatively testing, analyzing, evaluating and validating novel design frameworks.

A thorough training in both fundamentals of design methods and CAPE tools as well as in the associated work processes is required to become an expert designer. Manufacturing and engineering companies in the Netherlands have indicated that a more advanced training in design is needed to meet the upper range of design capabilities. The Dutch chemical engineering departments responded by developing specialised two-year postgraduate studies in process systems design. As an example the structure and contents of a post-graduate study in process design at Delft University of Technology is highlighted and evaluated.

A reduction approach is introduced addressing both features, while systematically going through the usual model development steps. Thus, the reduction is not applied only at mathematical and numerical level, but at physical and systemic level as well. The benefit is that the model reduction is achieved while retaining the topological structure of the processand the meaning of the variables. The application of the approach ...
