Mercury in production fluid O&G equipment

[ToxicHero]

Hello Guys,

I was wondering whether you know good publication about influence of Mercury on materials in production fluid environment? Especially with level, range of mercury.

I have looked through the internet/forums, but there is lot of information about impact Mercury on health/environment. But little about effects on materials. Only one interesting publication which I have found was "Mercury in petroleum and Natural Gas" S.M. Williams and such link:

http://www.gaschem.com/mercur.html,

but still unfortunately it is not enough for me. I heard about amalgamation of materials and Liquid embrittlement cracking - but I would like to understand mechanisms, levels of mercury when this happens etc

I need to write report if there would be harmful effects of Mercury in production fluid on SVXT an Tubing Hanger system: Level : 51ppb in the liquid phase and 29um/SCM in gaseous phase.

If you would have any titles, links etc I would much appreciate to share it

Thanks in advance all.

Look up 'liquid metal embrittlement' and you will find lots of Hg papers.
Monel is very susceptible to LME from Hg at room temp.

I have seen a couple of kg of Hg drained from the bottom of a separator tank.

I wonder if the effect of amalgamation with metallic mercury has any relevance to how mercury ions in solution behave. I suspect that they are different because I not heard of mercury salts having such an effect.

The first thing that you need to know is what form the mercury takes in the system under study.

Thanks a lot for you help, all, Much appreciate. I will look into them.

I will try to learn what form of mercury is in the system..
