Low-temperature methanol washing
Thread Content
Why does the liquid level in the scrubber first rise and then fall when low-temperature methanol is used to reprocess the gas? I’ve just started working with acid removal! Please, senior colleagues, explain it to us
When gas is first introduced, the uneven contact between the liquid and the gas can cause brief splashing of the liquid; otherwise, there may be a problem with the distributor on your tray
Theoretically, when gas is first introduced, the rising gas causes a certain layer of liquid to accumulate on the tray, resulting in a decrease in the liquid level in the tower. Then, as methanol absorbs acidic gases and increases the volume of the solution, the liquid level rises slightly. However, fluctuations in liquid level caused by variations in the amount of air introduced cannot be ruled out.
