LME by Hg
LME by Hg
(OP)
In order to protect a BAHX (aka "cold box") from LME, we have started measuring Hg in the inlet gas.
Question 1) What's the minimimum amount of Hg that will cause LME? is there a published threshold value?
Question 2)What's the most effective non-destructive test (non-intrusive) to detect Hg in such equipment (completely insulated)?
Thanks,
Corgas

2) Surely, trying to detect mercury is not an ALARP measure. If you have a susceptible material and liquid mercury will drop out, you have two options: change the material, or remove the mercury upstream
For aluminium, there will also be an amalgam corrosion risk if water is present.

In general if there is free Hg then you have an issue.

even in the ppb range will cause LME?

It all comes down to this : Based on the Hg coming in with the gas, when do we need one of those fancy Hg removal systems in order to protect BAHXs?
