stripping flue gas from rust particles with a spray tower

[Yobbo]

L.S.,

I am confronted with the challenge to strip a large flue gas flow from rust particles. These particles are flake shaped with an area up to 2000 square millimeters and a thickness of 0.1 mm. I want to find out whether a spray tower could be a remedy to capture these particles. AFter studying the literature I see spray towers mentioned as a possible solution for my problem. However there seems to be some upper limit for the flow, but I haven't found the reason why. I have contacted Fisher Klosterman, but they just gave me a no without an explanation why. Appearantly the knowledge to size a spray tower is not based on public available scientific research. Maybe I looked for the wrong things.
I would be greatfull for any hints, literature references or contacts with companies that may be of service to me.

Awaiting your soon reply I remain,

The spray tower itself does not seem to me as the best possible solution.
You have flakes,
I would also consider impaction technologies where droplets would "catch" the scales. May be a venturi. Maybe a wet scrubber could do the job, with a much reduced pressuire drop.

More studies are required; but the spray tower (without a down stream baghouse filter) looks suspect to me, unless you manage a high spraying density.
