Process Integration Methodology
Process integration methods aim at identifying options for heat recovery and optimal energy conversion in industrial processes. For the heat cascade, it is assumed that any heat exchange between cold and hot streams is possible, but due to industrial constraints, in many cases, this assumption cannot be accepted in practice and it is necessary to impose restricted matches. This introduces energy penalties, which could be reduced by using intermediate heat transfer systems. A targeting method including industrial constraints to ensure feasible solutions is introduced.
