Has anyone encountered serious water carryover in sulfur quench towers? How to solve it
Thread Content
The flue gas at the top of the quench tower contains a large amount of water; the packing used is structured packing, and a wire mesh catcher is installed at the top of the tower, with the temperature at the top maintained at 30°C. Is it necessary to install a separator or an efficient mist catcher between the quench tower and the absorption tower? Do anyone have any good ideas for modifications? Please advise.
The temperature hasn’t exceeded the limit, and there’s no excessive amount of moisture entrainment again. Then we should consider whether the processing volume has increased Is it also possible that the screen catcher is damaged?
Under normal circumstances, when the liquid level in the quench tower is not high, the amount of water vapor carried is equal to the amount of water vapor at the saturated temperature. If there is a significant increase in the amount of water vapor carried, I believe it is due to two main factors: first, the liquid level in the quench tower is high; second, the volume of hydrogenation exhaust gas is too large, resulting in a high gas flow rate. However, if the gas flow rate is too high, the temperature should not decrease as expected.
