hedgehog packing in scrubber

[sjputtick]

I am looking at the re-use of an existing scrubber which uses 'hedgehog' packing. I don't have any data on the packing characteristics. Does anyone have any data on this type of packing or any idea where to find any?

You got me on this one. Can you come back with a little more description as I have been around a long time and never heard that term.
The only thing that I've ever seen that could remotely resemble a hedgehog is a plastic variation on the Berl or Intalox Saddle. Could it be a Telleratte?

Perhaps they also have another name. The original spec is Swiss, and mentions Igel (Igel is german for hedgehog).

A few years ago we had the same problem: considered they were equivalent to 2" Pall Rings (for Kga) and the scrubber has been running well ever since.

Looking at the amount of surface area it looks like they should perform better than a pall ring in clean system, if you can find one.
I would check with Clemson and see if they have some data either the manufacturer or from the unit operations lab.
