Abstract:
1. A system for regenerable sulfur removal comprising: a gaseous source for providing a gaseous flow in a first direction; a regenerable sulfur remover comprising a first layer in line with said gaseous flow and a second layer in line with said first layer, wherein said first layer comprises a physical absorber of sulfur, wherein said physical absorber is effective to absorb sulfur from said gaseous flow when said gaseous flow is passed over said first layer, and wherein said second layer comprises a pyrophoric material; a blower configured to feed an unheated air flow first over said second layer and then over said first layer; wherein said pyrophoric material of said second layer is effective to heat said unheated air flow when said unheated air flow is passed over said pyrophoric material of said second layer to provide a heated air flow; and wherein said heated air flow is effective to remove absorbed sulfur from said first layer when said heated air flow is passed over said first layer; and an exhaust configured to remove said heated air flow after said air heated flow is passed over said first layer.
