Comparison of analytical methods of design calculation of continuous steady-state chemical-process schemes
Analytical and integral methods can be distinguished along existing techniques for design calculation of continuous steady-state chemical-process schemes (CPS). Analytical methods are oriented either toward CPS structure (modular approach) or toward the structure of the equations providing a mathematical description of the CPS. This paper discusses a number of examples of analytical methods for CPS design. In comparison with the modular approach, the equation-oriented approach generally involves a smaller number of iteration variables, fewer total iterations, and less computer time for direct solution of the equation system for CPS mathematical description; there are no multilevel CPS design calculation procedures (no nested iterations). Their method is recommended for solution of CPS optimization problems where numerous system design calculations are required. Because of the flexibility of the algorithm, the choice of control variables reduces in a number of instances to noniterative CPS calculations for each stage of the optimal regime search.
