Abstract

The modern technologies for production of elemental sulfur from gases are analytically reviewed. Along with the wide application of the conventional alumina catalyst in the conventional Claus process, new trends are formulated and generalized, which may significantly influence the technological picture of recovered sulfur manufacturing, such as active development of Claus tail gas cleanup processes with an emphasis on replacement of subdewpoint processes of Sulfreen type by processes of hydrogen sulfide selective oxidation by oxygen; development of novel highly efficient technologies for hydrogen sulfide decomposition to sulfur and hydrogen; application of new catalyst forms (primarily on microfiber supports) for Claus processes and H2S oxidation; wider application of titanium and vanadium catalysts in newly constructed Claus units; and development of technologies and catalysts for direct purification of H2Scontaining gases and catalytic reduction of SO2 for sulfur recovery from smelter gases.
