Humidity Issues in Wet Scrubbers

[Fabcap]

I am tasked with designing a scrubber for fumes from a steel pickling plant.

The HCl removal part is no big deal, but I am not sure what to do about the humidity.

Fumes come at 60 °C, carrying a substantial amount of water vapor. If they are contacted with water around 35 °C, this vapor will tend to condense.

What I would like to know is if I have to take into account the dehumidification of the fumes when designing the scrubber, or if I can ignore it.

Or is there any shortcut, rule-of-thumb method to tackle this problem?

...."Fumes come at 60 °C, carrying a substantial amount of water vapor...." Well with that statement I would not discount the condensation amount from the design. Do the math assuming 0% and 100% of vapor being condensed.

Well, it's not a big deal to take into account the humidity. I would do it.

Yes, I designed the scrubber to take the humidity into account as well.

I would designe it to take into account 100% of the water vapor entrained in the fumes realizing that not all of the water vapor will condense.
