Basic Sulfur Recovery Research. Annual Technical Report, January 31, 1991

摘要

The fundamentals of chemical interactions between chemical reagents and reducedsulfur compounds in the liquid redox and other sulfur recovery processes are explored in order to use the information to target the most effective options in processing steps for the gas industry. Methods for following concentration of an intermediate chemical species in the reaction of iron chelates and hydrogen sulfide were developed. Additional kinetic methods involving ultraviolet spectroscopy and sulfide ion selective electrode measurements were developed for following the chemical reactants during key stages of the reactions.
