Issues in selecting combustible gas detectors
Thread Content
I would like to ask the experts here: are there any combustible gas detectors suitable for use in conditions of high temperature (250°C), high pressure (7 MPa), and high humidity? Thank you!
This requires an online analyzer. Gas detectors are suitable for detecting gases in the atmospheric environment; one can refer to the calibration specifications for such detectors. . . i
What was said upstairs is correct; if the conditions are indeed that high in pressure and temperature, you can draw the sample out to reduce the pressure and temperature before taking further measurements, as long as it doesn’t affect the composition of the sample
Are there any online analyzers suitable for such operating conditions?

For example, if a tank is under high temperature (250°C) and high pressure (7 MPa), a combustible gas detector can only measure the gases leaking from the container; therefore, the measurement is taken at ambient temperature/atmospheric pressure, and the gas being measured has already mixed with the atmosphere. If you want to determine the components of a gas, it is usually necessary to cool and depressurize it before sending it to an on-line analyzer; the sample gas from the analyzer does not mix with the ambient air. In other words, after reducing the temperature and pressure, it can also be used with gas detectors; make sure the measured concentration is appropriate.
Thank you:handshake
Pay attention to the oxygen concentration, as it does not mix with the atmosphere; the oxygen concentration is likely to fall below the level required for combustion, making detection impossible. (Of course, this is a catalytic combustion type.)
