Question
As a new engineer, you plan to propose a heat exchanger network design of the processing
plant. After consideration of available data provided by the plant manager, the stream data
extracted as in Table 4. You were measured the energy target using problem table analysis
and know that this plant has threshold problem and only need 14.02 MW of hot utilities at the
minimum permissible temperature difference, 10°C. Design the heat exchanger network
(HEN) for the plant with given pinch temperature, 45°C. Show details calculation of feasibility
for all heat exchangers involved.
