Correct Integration
Process, Energy and System
Applications:
Heat Exchanger Networks (done !)
Distillation Columns (and Evaporators)
Heat Engines (such as Steam Turbines)
Heat Pumps (both closed and open)
Qualitative Approach:
Based on Pinch Decomposit

What about Retrofit Design of
Heat Exchanger Networks ?
Process, Energy and System
Optimal Retrofit Optimal Grassroot
Optimal Reuse of installed Heat Exchangers
Requires accurate Modeling (Rating)
Shorter Paybacks (especially Energy Projects)
