Durability Testing of the Direct Sulfur Recovery Process

Conference ·
OSTI ID:16001
Designs for advanced integrated gasification combined cycle (IGCC) power systems call for desulfurization of coal gasifier gas at high-temperature, high-pressure (HTHP) conditions using highly efficient, regenerable metal oxides such as zinc titanate. Regeneration of the sulfided sorbent using an oxygen-containing gas stream results in a sulfur dioxide (SO{sub 2})-containing off-gas at HTHP conditions. The patented Direct Sulfur Recovery Process (DSRP) developed by the Research Triangle Institute (RTI) with Morgantown Energy Technology Center (METC) support is an attractive option for treatment of this regeneration off-gas. Using a slipstream of coal gas as a reducing agent, it efficiently converts the SO{sub 2} to elemental sulfur, an essential industrial commodity that is easily stored and transported.
