Method for determining concentration of hydrogen sulfide in sulfur-containing raw and residual oil involves generating hydrogen sulfide by passing carrier gas into sulfur-rich mineral-oil solution and analyzing hydrogen-sulfide content

摘要

Method for determining concentration of hydrogen sulfide in sulfur-containing raw and residual oil involves dissolving sulfur-rich mineral oil in solvent or solvent mixture at 200[deg] C or more, passing carrier gas through the solution at 80[deg] C or more, generating hydrogen sulfide and carrying out quantitative analysis of generated hydrogen sulfide.
