Why does the dust concentration at the inlet of the flue gas extractor in a catalytic cracking unit show a positive correlation with atmospheric temperature?
Thread Content
The device is operating well, but there is a positive correlation between the dust concentration at the inlet of the smoke extractor and the atmospheric temperature; the dust concentration also varies significantly when the temperature difference between day and night is large. I would appreciate any guidance you can provide.
It must be related to the instrument measurements and the temperature differences between day and night.
Temperature has a significant impact on air density
It’s probably a problem with the instrument. Our measurements have never been accurate.
It’s a gauge issue; temperature affects the main air flow and flue gas volume, but it should have little impact on flue gas dust
In this regard, we have modified our original measurement methods; laser measurement has its limitations. Our dust concentration measurement method based on the principle of electrostatic induction has proven to be very effective in Sinopec’s enterprises. This product comes with certification for accurate measurement, and it is not affected by moisture, high temperatures, or vibrations. It also requires no maintenance.
