Heliflow Exercise
Task:
A water treatment plant uses Heliflow technology for preheating seawater before it enters the desalination process. The plant needs to increase its daily desalination capacity.
Problem:
- Currently, the plant uses a single STBHE to preheat the seawater.
- The existing STBHE has a limited heat transfer capacity.
Objective:
- Propose a Heliflow solution to increase the plant's desalination capacity while maintaining energy efficiency.
- Briefly explain your solution and how it addresses the problem.
Exercice Correction
**Solution:**
Instead of using a single STBHE, the plant could implement a parallel arrangement of multiple STBHEs. This solution would increase the overall heat transfer surface area and therefore increase the preheating capacity, allowing for higher desalination throughput.
**Explanation:**
By adding more STBHEs in parallel, the plant can distribute the seawater flow across multiple heat exchangers. This allows each exchanger to handle a smaller portion of the flow, thus increasing the overall preheating capacity. The parallel arrangement also allows for redundancy, ensuring that if one STBHE malfunctions, the others can continue to operate, minimizing downtime and maximizing desalination output. This approach is more energy-efficient than using a single large STBHE because it can be tailored to the specific flow rate and preheating requirements of the plant, ensuring optimal performance and minimal energy waste.
