Heat Exchanger Design for Dilute Aqueous Solution and Steam Condensate
Given that a process stream of dilute aqueous solution and steam condensate are flowing at the same rate of 10 Kg.s-1, and a 1-1 shell and tube heat exchanger is available. We need to determine the best arrangement for this heat exchanger.
Counter Flow with Process Stream on Shell Side is the Best Arrangement
The best arrangement for this heat exchanger is counter flow with the process stream on the shell side.
Explanation:
1. Counter Flow Heat Exchanger
Counter flow is the most efficient arrangement for a heat exchanger. In this arrangement, the hot and cold fluids flow in opposite directions. The counter flow arrangement provides the highest temperature difference between the two fluids at any point along the length of the heat exchanger. This results in a higher overall heat transfer coefficient and a more compact heat exchanger.
2. Process Stream on Shell Side
In this case, the dilute aqueous solution is the process stream, and it is flowing on the shell side. The steam condensate is flowing on the tube side.
The reasons for choosing this arrangement are:
- The dilute aqueous solution is the fluid that needs to be heated. It has a lower heat transfer coefficient compared to steam condensate. Therefore, it is better to have it flow on the shell side, where it can be exposed to a larger surface area of the heat exchanger tubes. This will enhance heat transfer.
- Steam condensate has a higher heat transfer coefficient, and it is better to have it flow on the tube side, where it can provide a higher heat transfer rate.
Conclusion:
In conclusion, the best arrangement for this heat exchanger is counter flow with the process stream on the shell side. This arrangement will result in a more efficient heat transfer and a more compact heat exchanger.
