ROCKEVAL 7S for renewable and cleaner energies, through soil and basement management for more safety
The Rock-Eval 7S is very useful to assess total sulfur, organic sulfur, mineral sulfur, sulphites and sulphates in the soils and rocks.
* Too high concentrations of SO2 can lead to acidification of the environment. Once emitted into the air and in the presence of water, SO2 is transformed into sulfuric acid H2SO4 which contributes to the phenomenon of acid rain. The consequences of such rains are acid depositions on building materials which can cause damage to architectural and cultural heritage, acidification of surface water leading to the death of fish and soil deterioration which can have adverse effects on the environment. vegetation and plants. The decrease in the concentration of sulfur in fuels, by refining processes, has made it possible to reduce this acid rain, but the detection of sulfur as early as oil exploration makes it possible to understand the mechanisms by which sulfur is incorporated into organic matter, and to calculate in advance the sulfur content of the extracted products. Likewise, the quantification of H2S (gas corrosive for installations, and dangerous for operators) in rocks from exploratory drilling, is an important issue for the sizing of extraction tools. With the Rock-Eval7S we can detect total sulfur, organic sulfur, mineral sulfur, sulphites and sulphates.
* In the field of soil oil pollution, the Rock-Eval analysis allows a rapid diagnosis of the quantity of pollutants and the type of oil present, for a quick decision on the choice of the decontamination method. This method also makes it possible to determine in near real time the volume of polluted soil and to compare the effectiveness of the decontamination processes implemented over time.
* In the field of geothermal energy, the Rock-Eval can be used for the characterization of samples of various kinds such as: (1) solid deposits present in exchangers, (2) lubricants used in geothermal installations and (3) corrosion inhibitors intended for the protection of geothermal installations.
* In the field of cement industry, the Rock-Eval allows to quantify the total amount of carbon, as well as sulphur, embedded into the natural raw material, in order to better assess the carbon emissions.
