Sample interview questions: How do you approach analyzing and troubleshooting issues related to heat transfer in petrochemical engineering?
Sample answer:
1. Gather data and define the problem.
- Collect operating data, including temperatures, pressures, flow rates, and heat transfer coefficients.
- Conduct visual inspections and non-destructive testing to identify potential hotspots or cold spots.
- Determine the root cause of the heat transfer issue, considering factors such as fouling, corrosion, or design flaws.
2. Evaluate the heat transfer system.
- Calculate heat transfer rates using appropriate equations and models.
- Identify areas of high or low heat transfer efficiency.
- Conduct thermal analysis to determine the temperature distribution and identify bottlenecks.
3. Develop and implement solutions.
- Recommend modifications to operating conditions, such as increasing flow rates or adjusting temperatures.
- Suggest design changes, such as adding baffles or modi… Read full answer
