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 H2S content arising during the warm storage of sulfur-containing crude and residual oils and mineral distillates containing sulfur-containing crude and/or residual oils, in which a sample of the sulfur-containing mineral oil is dissolved in a solvent or solvent mixture that boils at more than 200° C and a carrier gas is caused to flow through the solution of the sulfur-containing mineral oil at temperatures above 80° C, and the quantity of hydrogen disulfide carried out with the carrier gas is analyzed quantitatively.
