METHOD FOR DETERMINING THE CONTENT OF HYDROGEN SULFIDE IN CRUDE AND RESIDUE OILS

摘要

The subject of the invention is a method for determining the H2Scontent arising during the warm storage of sulfur-containing crude andresidual oilsand mineral distillates containing sulfur-containing crude and/or residualoils, in whicha sample of the sulfur-containing mineral oil is dissolved in a solvent orsolventmixture that boils at more than 200° C and a carrier gas is caused toflow through thesolution of the sulfur-containing mineral oil at temperatures above 80°C, and thequantity of hydrogen disulfide carried out with the carrier gas is analyzedquantitatively.
