Column conversion, Structured to random
« on: July 14, 2008, 10:03:35 AM »
Hi

We have a column that has structured packing in that has collapsed and not giving us the fractionation.

Given both time and cost restrictions, the best solution we can see is the removal of the structured packing and the filling of the column with random packing.

Is it possible to give a very rough figure for difference between random and structured packing?

Column is 1 m x 6m

Thanks

Hello enzyme76,

I do not have the exact information that you are looking at achieving, but I may have some information that can point you in the right direction.

In the oilfield, Rasching Rings (http://en.wikipedia.org/wiki/Raschig_ring) are commonly used, and you may be able to determine the porosity of structured packing (spherical media - http://en.wikipedia.org/wiki/Porosity). By performing a quick test with media in a laboratory, you can determine the displaced space inbetween each media by filling the pore spaces with water.

This could help you determine the spacing requirements.

This may also help you identify the reasons why the structured packing may have collapsed.

I hope this helps.

Sincerely,

Eugene
