Trend chart of the effect of pressure on low-temperature methanol washing absorption
Thread Content
Who has a trend chart showing the impact of operating conditions (pressure) on desulfurization and decarbonization in low-temperature methanol washing? In my experience, pressure has little effect on absorption (circulation rate); the comparison pressures are 5 MPa and 3 MPa
Is there such a drawing? I want to learn * too. However, pressure still has a significant impact on absorption in our operations.
Once the impact of stress reaches a certain level, it has little effect anymore
It doesn’t matter whether you know or not; the operational pressure remains basically constant. Of course, this is a form of physical absorption; an increase in pressure certainly facilitates absorption.
I’m sorry, I forgot to answer the question just now. Based on my experience operating absorption towers, I believe that in terms of practical adjustments, when dealing with the same amount of process gas and the same circulation volume, higher pressure operating conditions will certainly result in a better absorption effect, allowing the circulation volume to be reduced appropriately. If data is needed for comparative calculations, I hope some expert can provide experimental data or theoretical diagrams; I would like to learn about this as well, because it’s not possible to rely solely on practice without a theoretical foundation.
