METHOD AND APPARATUS FOR FAST QUALITATIVE AND QUANTITATIVE DETERMINATION OF SULPHUR IN SEDIMENTARY ROCKS AND OIL PRODUCTS

摘要

FIELD: chemistry.SUBSTANCE: in the method for qualitative and quantitative determination of sulphur in a sample of sedimentary rocks or oil products, wherein the following steps are carried out: heating said sample in a pyrolysis furnace in a non-oxidising atmosphere; transferring the pyrolysis residue of said sample into an oxidative furnace and continuous measurement of the amount of SOin effluent obtained from said oxidative heating; oxidising a portion of the streams from pyrolysis and continuous measurement of the amount of SOin said portion after oxidation. An apparatus to this end is also disclosed.EFFECT: high information content and reliability of determination.12 cl, 6 dwg
