In a process design, the following process streams must be cooled or heated:

• Determine the temperature interval diagram.
• Determine the cascade diagram, the pinch temperatures, and the minimum hot and cold utilities.
• Determine the minimum number of heat exchangers above and below the pinch.
• Determine a valid heat-exchanger network above the pinch.
• Determine a valid heat-exchanger network below the pinch.
