Scrubber sizing

dan140465 · 20th August 2006, 20:42

Can anyone provide a link to or give info on calculating scrubber sizes, ie a scubber sized as for the inspo will give approx 3 hours based on certain conditions.
But if you wanted say half the duration ?
Regards
Danny

Dan,

Duration doesnt just depend on Absorbent mass, its also effected by scrubber architecture and geometry.

So the short answer is that you'll get educated guesses, nothing more.

I've got an OLD USN report I've been trying to upload that illustrates this....
