You need to sub-cool condensate from a methanol condenser from 95°C to 40°C. Flow-rate of methanol is 100,000 kg/h. Brackish water will be used as the coolant, with a temperature rise from 25°C to 40°C.
(a) Identify and justify the most suitable heat exchanger type, flow scheme (parallel or counter), and fluid allocation (which fluid will be at tube-side and which will be at shell-side) for this specific heat transfer problem.
(b) Acquire and enlist all the necessary knowledge from open literature to determine the overall heat transfer coefficient for your identified heat exchanger in part (a).
(c) Apply the information and knowledge you obtained in parts (a) and (b) to calculate the overall heat transfer coefficient for an efficient heat exchange between methanol condensate and brackish water.
