Question: How can plate heat exchangers address the crystallization issue?
Thread Content
When using plate heat exchangers, some chemical processing units encounter crystallization problems – how should these be addressed?
1. Increase the material flow rate; 2. Take into account the material’s crystallization temperature – the temperature of the material after heat exchange must not be lower than this crystallization temperature.
The problem is that it doesn’t crystallize during use, but it does after the machine is shut down; as a result, it cannot operate when started up again. Is there any good solution for this issue?
Because after each shutdown, some materials remain and crystallize, which affects normal startup the next time. Is there a good solution for this problem?
Add three connectors and control valves on both the inlet and outlet sides, and install a set of replacement and cleaning pipelines so that cleaning can be carried out immediately once operation stops.
Oh, thank you, that’s a good idea.
That’s right; install a cleaning pipeline and clean it promptly when it’s not in use! ! ! ! ! ! ! ! ! ! ! ! ! !
Who designed and installed this? How can they be so incompetent as to make such a basic mistake? It’s extremely unprofessional. All evaporation systems are equipped with a cleaning function; before shutting down, everything inside must be cleaned
