Design a shell and tube heat exchanger to be used as a heavy paraffinic hydrocarbon stream (n-hexadecane) cooler. Hexadecane at a flow rate of 120 kg/s enters the heat exchanger at 102°C and leaves at 65°C. The coolant to be used is city water entering the heat exchanger at 21°C with a flow rate of 65 kg/s. Shell side pressure drop is limited to 150 kPa, while the tube side pressure drop shouldn’t exceed 40 kPa. A detailed design based on the Simplified Delaware method with the most valid assumptions is required.
