Monitoring and analysis of Hydrochloric Acid mist at pickling line scrubber

Is there any process/method to monitor and analyse ACID MIST (hydrochloric acid) in mg/Nm3. These fumes are emitted through the pickling line scrubber at 55 °C. There is a provision to extract the fumes through the sampling port which is just above the scrubber section.

Hi T.S.,

A weirdish question ... but why do you want to measure the HCl carry-over .... do you have a lousy scrubber?

Then you mention a temperature of 55 °C ! Is that from the tank you are exhausting ... in which case the temperature would be far less due to the cooling effect of the airstream. That seems to be horribly high.

On exhausting 100% HCl from loading/unloading, we achieved virtually 100% knock-out but the spray water content had to be fairly high ... this is done at ambient and also at minus 20 ° C

Actually, what is a bit "weirdish", Freeman, is your effort to make the answer to every question "inertial mist eliminator" :-)
We're used to that quirkiness after all these years, old friend, but if you have to insult a person's question in order to do it, that should be a sign to you that it would be weirdish to go quite that far.

There is a device/system called a "Draeger tube." This is a little sealed glass tube filled with an absorbent that is spiked with an indicator. It is used with a little hand pump. The glass seals at each end are broken off, and the tube is inserted in the pump. The pump is then given a set number of strokes, and the contaminant level is read by inspecting the tube and seeing how far down the column of indicating absorbent the color change travels. Each tube has graduations marked on the side, so you can put a number to the measurement.
