This post was last edited by adsl121 on 2011-1-24 00:19. What is the typical temperature range for the low temperature section of a regeneration tower? What is the decomposition temperature of the amine solution? Are there any confirmed documents available? Is it related to concentration? Participate actively
The low temperature in the regeneration tower is generally kept around 120 degrees. N-methyldiethanolamine is a commonly used desulfurizing agent with a boiling point of around 247°; it should remain stable below this temperature. During regeneration, there is no need to give too much consideration to its decomposition temperature, as it is unlikely to have any impact.

The low temperature in the regeneration tower is generally kept around 115 to 125 degrees. N-methyldiethanolamine is a commonly used desulfurizing agent, with a decomposition temperature of around 140–150 °C; it should remain stable below this temperature. During regeneration, there is no need to give too much consideration to its decomposition temperature, as it is unlikely to have any impact.
It must be the boiling point of water at that corresponding temperature and pressure!
The low temperature in the regeneration tower is generally maintained between 122 and 125°C. The decomposition temperature of the amine solution is related to its concentration; the boiling point of pure MDEA is between 246 and 248°C℃
I’m struggling with the problems in the desulfurization unit
