Flexibility analysis of chemical plant based on MATLAB

The necessity and practical method of flexibility analysis of chemical plant are demonstrated in this paper. As an example, an index method is applied to analyze a float valve tower to determine the variation range of some uncertain parameters. Flexibility of different designs are compared and their bottlenecks are also worked out, thus to provide theoretical basis for the retrofit of a chemical plant. Calculation of the flexibility is conducted by way of MATLAB programming because of its simple algorithm and polished language. The algorithm used by this paper makes a universal tool for flexibility analysis of chemical plant.
