process variables. This MINLP approach can be used to detect the likely occurrence of a snowball effect in a plant and to develop control architectures that can avoid this problem. The optimization -based approach is illustrated on a three - reactor three-distillation column plant taken from the literature. Introduction The design of plantwide control systems has received increasing attention This paper describes the design of a control structure for a large-scale process known as the HDA plant. A steady-state "top-down" analysis and optimization of the process (described in Part I of He has worked on plant improvement studies and on the design of new facilities. Luyben has authored a number of papers on plantwide control and on the interaction of process design and process control. Michael L. Luyben is currently a research Engineer with Du Pont's Central Research and Development Department. To Janet Niche! Luyhen-m.othec 2Centre for Process Systems Engineering, have increasingly been used in plantwide control (PWC) studies in recent years. These software programs can be used for steady-state modeling and analysis, as well as for dynamic simulation and performance analysis of the PWC structures. The use of dynamic simulators has been covered thoroughly in the book by Luyben (2002). The issues covered in his INTRODUCTION Plantwide control (PWC) refers to the structural and strategic decisions involved in the control system design of a complete plant, including the following tasks, see (Foss, 1973) (Skogestad et al., 2000): · · · · Selection of controlled variables. Selection of measured variables. Selection of manipulated variables. Plantwide control system design for economically optimum operation of a C4 isomerization process is studied. The steady state degrees of freedom of a base case design are optimized for a given C4 Luyben W.L.
