A new hybrid optimisation method is presented, that is fairly robust and can be accomplished in an automatic way. The main idea is using integer cuts and bounds, calculated based on driving force plot analysis, for the lean streams to decrease the possibility of being trapped in local optimum. A new initial solution is constructed only if the MINLP solution is infeasible, otherwise the best solution found earlier is used. In consequence, the MINLP model changes in the iteration steps. The iteration is stopped if the total annual cost (TAC) in the solution is less than 1.1 *TACtarget.
