The patented Fluor SOx Clean-up Process focuses on SO2 in various applications such as smelter and other flue gases. Most of these processes are still in the near-commercialized stages and are exploring application opportunities in the Claus tail gas treating environment. SO2 associated corrosion issues usually make the clean-up process capital intensive. Fluor's SOx Clean-up process is able remove nearly all SO2 without associated SO2 corrosion issues while simultaneously reducing the CO emission level.
The Fluor SOx Clean-up process was developed to reduce sulfur emissions from gas streams containing oxygen and sulfur oxides. It is an extension of the well-known Claus tail gas treating process. All the processing steps and equipment in the Fluor SOx Clean-up Process are proven in typical Claus sulfur recovery units and tail gas treating units. The processing capabilities of this equipment is well understood and proven in many operating plants worldwide.
