I have a question about solvents
Thread Content
They all talk about solvent concentration, but how is it done?
Adjust the temperatures of the quench tower and the absorption tower so that the temperature at the outlet of the quench tower is higher than that in the absorption tower; as a result, the liquid levels in both the absorption tower and the regeneration tower gradually decrease, and the solvent is thus concentrated
That’s the opposite; it should be the case that the outlet temperature of the quench tower is kept below the outlet temperature of the absorption tower. Additionally, some of the reflux liquid from the external regeneration tower can also be used to increase the concentration of the desulfurization agent.
It seems the poster is talking about heating acidic gases to separate them, thereby regenerating the solvent, right? !

Concentration enhancement means increasing the concentration of the solvent; it is necessary to calculate in advance how much water needs to be removed in order to raise the concentration to a certain level. Usually, the acidic water coming out of the regeneration tower is sent to the acid gas treatment unit.
