METHOD AND DEVICE FOR QUICK QUALITATIVE AND QUANTITATIVE DETERMINATION OF SULFUR IN SEDIMENTARY ROCKS AND IN OIL PRODUCTS

摘要

1. A method for the qualitative and quantitative determination of sulfur in a sample of sedimentary rock or oil products, in which the following steps are carried out: - heating the specified sample in a pyrolysis furnace (1) in a non-oxidizing atmosphere, - transferring the pyrolysis residue of the specified sample to an oxidizing furnace (1 ') and continuous measuring the amount of SO in the effluent resulting from said oxidative heating — oxidizing a part of the streams from pyrolysis and continuously measuring the amount of SO in the specified part after oxidation. 2. The method according to claim 1, in which they measure: - the amount of hydrocarbon products CO and CO in the pyrolysis streams, - the amounts of CO and CO in the effluent resulting from said oxidative heating. The method according to one of claims 1 or 2, in which the temperature of the pyrolysis furnace is from 60 to 800 ° C. 4. The method according to one of claims 1 or 2, in which the temperature of the oxidizing furnace is from 100 to 1300 ° C. 5. The method according to one of claims 1 or 2, wherein said part of the pyrolysis streams is oxidized in a furnace containing a catalyst. A device for the qualitative and quantitative determination of sulfur in a sample of sedimentary rock or oil products, containing: - a furnace (1) for pyrolysis of the specified sample in a non-oxidizing atmosphere, - means for transferring the remainder of the pyrolysis of the specified sample into an oxidizing furnace (1 '), - means for continuous measurement of the amount of SOв outgoing streams obtained as a result of said oxidative heating are means (5) for oxidizing part of the streams from pyrolysis; means (9) for continuously measuring the amount of SO in said part after oxidation. 7. The device according to claim 6, containing means of distribution (10) of the outgoing streams with pyrolysis�
