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

• The hottest hot-utility stream is high-pressure steam at 254°C. Use the MUMNE algorithm for heat-exchanger networks and a minimum approach temperature of 20°C.
• 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 heat-exchanger network above the pinch. (Be careful!)
• Determine the heat-exchanger network below the pinch.
