Knockout Tank and Condensor Design
Knockout Tank and Condensor Design
(OP)
Can anyone here help me estimate a efficiency for a knockout tank/plenum box?
I'm looking at two 10" influent pipe with process air going into a plenum box that acts as a knockout tank. I want to induce a pressure loss in the plenum box to help generate condensate. The effluent side has a single 14" line. the dimensions of the plenum box are 4'(W) x 30"(H) x 6'(L), and it has vertical condensation vanes in it spaced about an inch apart. The influent side is pressurized and the effluent side has a negative pressure. I do not know the pressure losses in the box. Is there a decent way of estimating the that pressure loss so I can estimate the condensate that will drop out in the box?
Thanks for your reply.

RE: Knockout Tank and Condensor Design
To estimate efficiency or pressure loss one needs flow, temperature, pressure information.
It would also help if one knew the equipment the plenum box was connected (a furnace ?)
The vertical condensation vanes sounds like a "chevron demister".
Does the plenum box have a liquid drain ??
In general, it takes less than 2-ft/sec gas velocity to knock out greater than 50 micron liquid drops at greater than 95% efficiency
