This B50TE assignment is a heat exchanger design project set in whisky distillation. Students design a TEMA AEU U-tube shell and tube exchanger that uses hot pot ale to preheat wash, justify the geometry they choose in HTRI, test how two parameter changes affect performance, and check HTRI’s duty, tube-side heat transfer coefficient and surface area with hand calculations.
In whisky distillation, the working fluid passes through several processes before it is casked and matured for a number of years. In the wash phase, pot ale (the waste by-product of wash still distillation, with little or no alcohol left and containing solids and residues) can be used to heat the wash (beer brewed for distillation, average ABV about 9%) before further distillation.
| Stream | Inlet temperature | Volume flow rate* | Outlet temperature | Tank volume |
|---|---|---|---|---|
| Wash (9% ABV water and ethanol mix) | 35 °C | 550 L/min | 70 °C (must be above 66 °C) | 15,000 L |
| Pot ale (treat as water) | 85 °C | 400 L/min | Unimportant (goes to waste) | 9,900 L |
*You may choose your own flow rates based on the capacity of the storage tanks.

Get Assignment Expert HelpDesign a suitable TEMA AEU U-tube shell and tube heat exchanger for heat recovery that maximises the wash outlet temperature. The wash can be brought to the final temperature with supplementary heating after the exchanger if required, and your design must justify any supplementary heating. Experiment with different geometries and arrangements, and justify your final recommendation against clearly defined criteria of your own.
For your chosen design, explain how two given parameter changes would affect the performance of the exchanger, first individually and then together. HTRI may be used to validate, but the effects must be explained. Keep the original dimensions and parameters constant where possible, although some changes will require a different exchanger size.
Perform a manual heat balance (duty) to confirm the HTRI calculation, remembering that one stream is a mixture of two fluids. Use an appropriate forced convection correlation to estimate the tube-side heat transfer coefficient and comment on how it compares with the HTRI value.
Using the heat transfer coefficients and tube data from HTRI, confirm the surface area by manual calculation (corrected LMTD or ε-NTU method) and comment on any difference between the manual and computer results.
