METHOD OF DETERMINING HYDROGEN SULFIDE IN MAZUT

摘要

analytical methods in petroleum processing. SUBSTANCE: hydrogen sulfide- containing mazut is diluted with organic solvent in 1:1 proportion and agitated until homogeneous mixture is obtained, from which hydrogen sulfide is displaced with inert gas in absorbing solution for 1-2 h. Once procedure completed, mixture is analyzed by known methods and hydrogen sulfide content is quantitatively determined. EFFECT: increased analytical accuracy. 2 cl, 1 dwg
