As mentioned above, the solids process synthesis approach (Rossiter and Douglas, 1986) has been applied to the optimization of a continuous salt crystallization plant similar to that depicted in Figure 9.2 (Rossiter, 1986). In... 

Note, however, that most of the research work in process synthesis has been based on the single-objective simplification with the notable exception of the recent work of Luyben and Floudas (1994a, b) on the interaction of design/synthesis and control. As a result, in the rest of this book we will focus on process synthesis approaches that are single-objective or decompose the original problem so as to become a single-objective problem. 

Procedures for the actual synthesis of heat-exchanger networks are somewhat less well developed however, all of the standard process synthesis approaches— including systematic generation, evolutionary modification, and superstructure... 

Consideration of nonideal systems and the effect of short-cut or approximate design methods on process synthesis approaches. 

The objective in the control or separation processes has evolved from the control of the components of a process that already has been designed and often constructed to an integrated plan involving simulation, desiga, and control. Chemical process synthesis approaches that jnclnde control structures have been suggested only recently and are not well developed.

A Multicriteria Process Synthesis Approach to the Design of Sustainable and Economic Utility Systems... 

The proper design criteria for a modem utility plant should include both environmental and economic requirements. In other words, not only the capital and operating costs of a utility plant but also the corresponding utility wastes must be minimised. The paper presents a systematic multicriteria process synthesis approach for designing sustainable and economic utility systems. The proposed approach enables the design engineer to systematically derive optimal utility systems which are economically sustainable and economic by embedding Life Cycle Assessment (LCA) principles within a multiple objective optimisation framework. It combines the merits of total site analysis, LCA, and multi-objective optimisation techniques...

The optimization component of process integration drives the iterations between synthesis and analysis toward an optimal closure. In many cases, optimization is also used within the synthesis activities. For instance, in the targeting approach for synthesis, the various objectives are reconciled using optimization. In the structure-based synthesis approach, optimization is typically the main framework for formulating and solving the synthesis task.

Process synthesis is a task of formulating the process configuration for a purpose by defining which operations or equipment are used and how they are connected together. There are two basic approaches for process synthesis 1) classical process synthesis, analysis and evaluation, and 2) optimization of process structure by using a suitable objective function. 

The Inherent Safety Index, ISI, was developed to consider a wider range of factors affecting the inherent safety of the process (Ch. 8). The ISI allows the evaluation of inherent safety of process alternatives to be done in a computerized process synthesis environment. The represented synthesis approach allows the inherent safety comparison of process alternatives to be done flexibly and interactively in the conceptual design phase. 

In the approach by Hurme and Heikkila (1998) inherent safety is the only objective function considered in the process synthesis. It is estimated by the Inherent Safety Index (Heikkila et al., 1996) which has been developed for...
