Operation of the regeneration tower for solvent regeneration
Thread Content
I have a question: what is the degradation temperature of the amine-poor liquid resulting from solvent regeneration? Recently, the temperature at the bottom of the tower reached almost 125°C; I’m not sure if this has an impact on the quality of the amine-poor liquid. If degradation does occur, what effects will it have on the regeneration tower? Another question is: what changes will occur in the parameters of the regeneration tower if the lean amine stream in it starts to foam?
125 is no problem at all; we have designed the temperature at the bottom of the tower to be 125°C. If degradation occurs, the concentration of the amine solution will decrease, and if foaming takes place, the liquid level in the regeneration tower will fluctuate significantly, increasing the risk of overfilling the tower!
125°C is no problem; here the temperature reaches up to 128°C. There is some degradation, but it’s minimal. After degradation, salts are formed, which renders the solvent ineffective and causes foaming. I read an article stating that at 138°C, 3% degradation occurs
After degradation, the solvent becomes ineffective and foaming is likely to occur; therefore, the amine system requires high standards for operation
Hello, after solvent foaming, apart from sampling for observation and chemical analysis, can any changes be observed in the parameters of the regeneration tower?

It’s not noticeable; generally, foaming does not occur, unless the concentration is high, in which case the situation mentioned on the first floor will happen
The possibility of foaming decreases significantly when the concentration is reduced; the presence of oil and hydrocarbons is inevitable in any case
Thank you for the reply; we will add more summaries in future productions.
What is the state of the amine liquid at the bottom of the tower at 125℃? Saturated?
