This paper presents an interactive MINLP solver that is particularly suitable for solution of process synthesis, design and analysis problems. The interactive MINLP solver is based on the decomposition based MINLP algorithms, where a NLP sub-problem is solved in the innerloop and a MILP master problem is solved in the outer-loop. The interactive MINLP solver allows a purely equation system mode (where all equations are given explicitly) and a simulation mode (where the process model equations are included and solved by the simulation engine of a simulator). These solution modes give flexibility in problem formulation and inclusion of different solution approaches. Applications of the interactive MINLP solver to the solution of typical CAPE problems are illustrated through several test problems.
