RE: Safe concentration of mercury in Natural gas
In general a level below 0.1 micrograms/Nm3 may be considered safe. You've indicated Al-air exchangers - is it something to do with regassification of LNG ? The Aluminium alloy is important if it has more of Mg it will be more susceptible to Hg attack. But remember even if the gas has Hg if the temp is below its melting point i.e. about -34 C Hg attack will not progress.

This is an interesting subject but unfortunately limited resources are available.

The resulting amalgam isolates the sensor's metal-oxide layer from the moisture in the natural gas resulting in a non-responsive sensor. This is particularly dangerous as the sensor will still output a signal thereby appearing as if it is still operating properly.
If your natural gas contains mercury, I would suggest using a technology other than a metal-oxide sensor.
