Reasons for high top temperature in the hydrogen sulfide removal tower for acidic water treatment and its impacts
Thread Content
What is an appropriate temperature control for the top of the tower used in acid water treatment to remove hydrogen sulfide? What causes the top and bottom temperatures of such a tower to be roughly the same? Our tower has two layers of packing in the upper part, while the lower part features floating valve trays
How could the temperatures be the same? The temperature at the top is controlled by the cold feed; if the temperature is too high, too much water vapor is carried upward
The cold feed has a normal temperature, at 150°C, and the hot feed is also only at 120°C; therefore I’m wondering if there might be some problem with the trays inside the tower that’s causing this situation
