Abstract:
1. A process for the production of sulfur from sulfur dioxide (SO 2 )-containing effluent streams, the process comprising: a) forming a mixture of oxygen containing gas with a hydrocarbon gas stream and feeding this mixture together with a separate stream of sulfur dioxide containing gas in a single Catalytic reaction furnace zones, containing an “Alumina Monolith” which performs as an Active Catalyst wherein reactions occur at an elevated temperature for a period of time sufficient to produce an effluent stream comprising sulfur (S), hydrogen, CO, and water; b) the process comprises 2 different reaction zones: a single Catalytic reaction furnace zone, and a Claus Catalytic conversion zone; c) contacting the effluent gas stream from the catalytic reaction furnace zones in one or more Claus catalytic reaction stages comprising one or more catalysts; and; d) recovering elemental sulfur from the product gas stream.
