| A systematic procedure has been introduced for the computer-aided analysis and multiobjective optimal synthesis of a chemical process system. The analysis is based on the thermodynamic first- and second-laws. Maximation of the second-law efficiency or minimization of the dissipation of the available energy (exergy) is one of the objectives of optimal synthesis. The structure of the computer program (software) for implementing the procedure has been described. The line code is used to represent material species throughout the program including the input and output. The program contains three major subroutines, namely, the physical and thermodynamic property estimation, system analysis and system synthesis. The use of the program has been illustrated with several examples in the areas of energy resources conversion, energy conservation and material processing. More specifically, the portland cement production process and methanation process have been systematically analyzed; the optimal synthesis of the methanation process has also been carried out. |
