- 1. Multiple Choice
Pinch Analysis involves an analysis of the potential maximum heat recovery for a process.
True
False
- 2. Multiple Choice
The minimum approach temperature difference (DTmin) between composite curves influences the heat transfer area, and the operating cost of a process.
True
False
- 3. Multiple Choice
The DTmin should be as small as possible to ensure that energy saving can be maximised and to maintain an overall process profitability.
True
False
- 4. Multiple Choice
The sum of heat excess (heat surplus) minus sum of heat demands equals the minimum energy targets for a process.
True
False
- 5. Multiple Choice
The shifted temperature interval is used to factor in energy losses from hot and cold composites
True
False
- 6. Multiple Choice
Setting the minimum energy target using Problem Table Analysis (PTA) is a process getting the overall sum of net enthalpies throughout temperature intervals.
True
False
- 7. Multiple Choice
In the PTA, a negative heat flow across temperature intervals will give the hot utility target.
True
False
- 8. Multiple Choice
If there exist energy surplus at a lower temperature interval, it is good to use it to satisfy energy demand at a higher temperature interval.
True
False
- 9. Multiple Choice
Heat can be transferred from low temperature to a high temperature, with the aid of energy.
True
False
- 10. Multiple Choice
Knowing the Pinch Point allows engineers to identify if there are suboptimal heat exchange within a process.
True
False
