How is the water quality of the heat transfer fluid in low-temperature heating systems monitored?
Thread Content
Nowadays, all factories have hot water stations that utilize heat transfer water to recover the low-temperature heat from various devices; for example, the heat generated at the top of catalytic distillation towers is used as a heat source for certain processing units. So how can the quality of this large-scale heat transfer water system be controlled? Moreover, leaks in the heat exchangers occur frequently, which contaminates the heat transfer water system. We suspect that corrosion is occurring in the heat transfer water, but we don’t know what to do about it Please, fellow sailors, share your advice!
Our current process is the same as yours; we plan to install oil-containing online analyzers on the low-temperature hot water pipelines. Early detection and early correction are possible.
It is sufficient to require the testing laboratory to analyze the mineral oil content on a daily basis. The previous oil removal facility performs regular oil removal to ensure that the water quality does not become emulsified. It’s best not to use overflow oil removal, as most of it is just water – it’s a shame.
We also previously leaked information; at present, we can only strengthen testing and analysis
Flow meters and pressure transmitters are installed on the inlet and outlet devices to facilitate comparison
