Risk assessment of primary water used in coolers
Thread Content
There is a heat exchanger that was originally designed to be cooled by circulating water; however, after calculations, it is now desired to use once-water that has been preliminarily clarified in place of the circulating water. In one of those cases, the water flows through the shell side of the heat exchanger, with the heat exchange tubes being made of stainless steel. However, there is no experience with long-term use of water, and there are concerns that debris may accumulate, affecting the heat exchange efficiency in the future. The water turbidity was less than 10 once. Experienced sea enthusiasts, please offer help. There is no need to discuss the economic aspects of water usage either; different processes require different approaches. Thank you
It’s better not to use it; if the water hardness is high, scaling and blockages can cause a lot of trouble. If the water temperature doesn’t exceed 40 degrees after heat exchange, then who says it’s not okay?
It cannot be used directly； The water was not treated once ； It should be processed ； Calcium reduction ； desalination ； Use after chlorine reduction
If it is possible to shut down this heat exchanger at any time or periodically for cleaning, that option can be considered; otherwise, it is prone to scaling or fouling and cannot operate for a long period of time
Generally, since water is used once only, its hardness does not become too high and does not accumulate. Therefore, can scaling be given less consideration? However, it is impossible to determine the trend from silt deposition, and this is also the reason for hesitation.
What does ‘one time water’ mean? ? ? ? ? ? ? ?
