The process synthesis problem formulated by using structure parameters becomes, in general, a highly constrained nonlinear programming problem. This paper shows that by the use of a transformation in constrained structure parameters, however, all the constraints on the structure parameters are eliminated from the problem. This transformation makes it possible to ease significantly the computational difficulty of handling constrained structure parameters. Two computational methods are proposed, in which the incorporation of the transformation in constrained structure parameters is presented. The results of synthesis of two examples are presented and compared with other methods of synthesis. Computational experience with examples has indicated that different methods must be adopted depending on the type of problem.
