Hydrogen sulphide content plays an extremely important role in a methane extraction programme destined for energy applications.

Generally, in fact, one considers that natural gas combustion in an engine cannot take place without rapid wear on mechanical parts (piston rings, cylinder etc.), if the level of H2S is over 500 ppm.
In the presence of water vapour and at high temperature the hydrogen sulphide is transformed into extremely corrosive sulphuric acid which tends to dangerously shorten the life of an installation's moving parts.


H2S content according to depth. Due to the limit of 200 ppm of our analyser the measurements were carried out on samples diluted 20 times, this explaining the relative dispersion of the results. The average hydrogen sulphide content is around 2500 +/- 500 ppm and does not seem to vary significantly with depth.
