The issue of methanol volume in the absorption tower.
Thread Content
I wonder who has the solubility data for methanol that has already absorbed carbon dioxide in absorbing hydrogen sulfide; I want to do the calculations myself to see if the reflux flow from our tower is too high. The temperatures of the two lower towers are -8 and -18 degrees respectively.
What process do you use? The solubility of methanol, which has absorbed carbon dioxide, for hydrogen sulfide is not a fixed value; it should be determined based on the load. The temperatures of the two towers in the lower section are -8 and -18 degrees respectively: it seems that there is excessive backflow in the lower tower. Experience shows that these two temperatures are roughly similar.
It’s not certain; it depends on the specific process and parameters. In our case at Dalian University of Technology, the two towers have different temperatures: one is at -7.5, and the other at -15
