What is the liquefaction temperature of hydrogen sulfide at 2.1 kilograms?
Thread Content
Can too low a temperature after cooling in the stripping tower easily lead to an inability to discharge the acidic gases at the top of the tower, resulting in the refined oil containing hydrogen sulfide?
The liquefaction temperature of hydrogen sulfide at 2.1 barA is -44.8°C, while at 2.1 barG it is -35.3°C℃
This is related to the pressure at the top of your tower, and it doesn’t have much to do with the temperature after cooling. A low temperature after cooling may cause the top temperature of the tower to drop; this can be addressed by appropriately reducing the reflux or increasing the bottom temperature of the tower.
