Why we need to avoid processes excessively large or excessively small thermodynamic driving forces(differences in temperature,pressure,composition)? Why we want to minimize the use of combustion? Why we do not heat refregerated streams with a stream at a temperature above ambient? For heat exchanger networks why we consider pinch method and exeegy related methods?
