Chlorine pressure measurement
Thread Content
Is it feasible to use a capillary pressure transmitter with a tantalum diaphragm, filled with silicone oil, for pressure measurement in a fluidized bed reactor where the medium contains chlorine gas and the temperature is 150 degrees? Should fluorinated oil be applied? Additionally, the operating temperature for fluorine oil is between -10 and 60 degrees; how is heat retention ensured in winter?
At high temperatures, chlorine reacts violently with silicone oil; the possibility of rupture at the membrane connections must be considered, so silicone oil should not be used
When encountering problematic gases, one option is to hold back the liquid so as not to come into contact with them while taking measurements; another option is to lower the temperature for measurement. By using a regular pressure gauge and taking indirect approaches, high-level safety and reliability in measurements can still be achieved. There’s no need to worry even if the diaphragm ruptures or silicone oil leaks. You can send me a **large red envelope – that would be great too. Hahaha :P
The capillary is filled with silicone oil, and it does not come into direct contact with the medium
How to choose the right material for the diaphragm is the key point. Your assumption is both plausible and implausible; it’s as if you’re saying: What if the pipe leaks?
Safety cannot be ignored. If you work in design, read the specifications more often
