ABSTRACT:
A process and system are set forth for improving the recovery of sulfur from an oxygen-enriched Claus process by introducing a liquid sulfur stream into the reaction furnace zone to moderate oxygen-induced high temperatures which allow oxygen-enrichment and attendant throughput in the Claus process to higher levels than heretobefore practiced and alternatively to quench the reaction furnace effluent to maintain a hydrogen sulfide dioxide ratio of 2:1.
