Batch processes, graphical analysis

In 1995, Wang and Smith developed a graphical analysis technique for water minimisation in batch processes, which forms the basis for the argument put forth in this chapter. A detailed presentation of this technique is, therefore, necessary in order to facilitate understanding of the subsequent sections of this chapter. 

Graphical Analysis for Completely Batch Processes 12.2.1 Problem Statement... 

Although simple distillation marks the first analysis of batch distillation process, the graphical analysis presented by [39] provided the basis for analyzing batch distillation operating modes. The difference between simple distillation and batch distillation operations is the relation between the distillate composition xd and the bottom composition xb due to the presence of reflux and column internals as shown in Figure 4.4. If one assumes constant molal overflow Lj = Lj-i =. . = Lo = L and Vj = Vj- =. . = Vi = V), then McCabe-Theile s method can be used. 

The graphical user interface of StackAnalyzer provides different views of the result, including visualizations of the call graph and control flow graph, and enables the information contained in the executable to be browsed in a user-friendly way. Creating AIS annotations is facilitated by a dedicated annotation wizard. These mechanisms help users to efficiently set up the analysis and evaluate the analysis results. After the configuration of the analysis and the assessment of the results the analysis can be executed in batch mode as a part of continuous verification processes or regression tests.
