Thermal Process Engineering
Heat exchanger network optimization• Pinch analysis• Grand and Composite curves• Exergy block diagram• Maximum heat integration and minimum
Utilities demand
• Targeting • Minimization of the Utilities demand• Heat load distribution• Minimization of the number of heat
exchangers• HEN Optimization• Simultaneous minimization of the Utilities demand and number of heat exchangers
as well as minimization of overall heat exchange area• Retrofit
