Hi all,

I'm trying to design an Absorption Column which will be included for the design of a natural gas processing plant.

The problem I have been having is that I am currently trying to calculate the height and diameter of the column but I am getting nowhere. I have been searching for data for the solubility of the water-teg mixture so that I can use this data to find equilibrium data and then use this to find my column height.

I have simulated my column on ChemCAD, and I have tried to obtain the data from this however the data from this does not seem to be correct where when I draw the data and plot charts, the charts seem to be very odd indeed. Therefore I would rather find data from literature.

If someone could help me on this that would be great! If more information on my design itself is needed please let me know.

Hi, I am doing dehydration unit in natural gas processing too. But I am designing regenerators. If you could look up for GPSA (Gas Processors Suppliers Association) Engineering Data Handbook, they have these shortcut method to calculate the column diameter and height out using correlation, there is no need of VLE/solubility data.

Hope this will help you.
