Method and device for fast sulfur characterization and quantification in sedimentary rocks and petroleum products

A device for sulfur characterization and quantification in a sample of sedimentary rocks or of petroleum products, comprising:

• a pyrolysis oven configured to heat said sample in a non-oxidizing atmosphere as to induce the release of pyrolysis effluents from said sample and induce the production of pyrolysis residues from said sample,
• an oxidation oven configured to heat the pyrolysis residues produced from said sample as to induce the release of effluents from said pyrolysis residues,
• means for transferring the pyrolysis residues produced from said sample into said oxidation oven,
• means for continuous measurement of the amount of SO2 contained in the effluents released from said pyrolysis residues,
• means for oxidizing part of the pyrolysis effluents released from said sample, and
• means for continuous measurement of the amount of SO2 contained in the effluents released from said sample after said oxidation.

• a SO2 detector continuously measuring the amount of SO2 contained in the effluents released from said pyrolysis residues,
• an effluent oxidizing oven receiving at least a portion of the pyrolysis effluents released from said sample, the effluent oxidizing oven configured to oxidize the received pyrolysis effluents, and
• a SO2 detector continuously measuring the amount of SO2 contained in the effluents released from said sample and oxidized in the effluent oxidizing oven.
