Reactor network synthesis is one of the key parts of chemical process synthesisHowever

the solution procedures are very complicatedThe concept of instantaneous value of objective function

and a geometrical method using the corresponding area of the curve of instantaneous value for reactor network synthesis were proposedThe application of the approach was illustrated with one case study involving complex reactionThe results were compared with the ones from referencesIt could be seen that the optimal reactor network could be obtained by using the approach

without solving the complicated largescale nonlinear programming problemThis approach is straightforward by using the geometrical method for reactor network synthesis.
