Is online measurement of ethylene glycol concentration done using a densitometer?
Thread Content
Our company wants to try online measurement of the ethylene glycol concentration at -15 degrees and -25 degrees, so as to be able to top up ethylene glycol at any time. Can the required level be achieved using an online densitometer? Has anyone else done something similar? Are there any recommended instrument manufacturers?
The measurements are taken in the freezing tank, mainly to determine the concentration of ethylene glycol at -25 degrees Celsius
Mainly 35% ethylene glycol and 42% ethylene glycol – it’s not clear whether these can be detected. Is ethylene glycol measured using a specialized concentrator?
The change in conductivity can be measured using conductivity
Can I get in touch? Please provide the specific process parameters!
It is the use of ethylene glycol as the heat tracing medium; it is possible for ethylene glycol at room temperature to mix into the frozen ethylene glycol, thereby reducing its concentration. We need to monitor the concentration of frozen ethylene glycol in real time, and add ethylene glycol to maintain it at a concentration of 42%
It can be measured; choose K.0.01 for the electrode K coefficient.
Is there a table for the conductivity of ethylene glycol aqueous solutions? Could you send it?
