Description:
Coal is the largest source of power generation in the U.S.A. but its conbustion produces SOx and NOx which must be removed from the flue gas. Current removal techniques (limestone base Flue Gas Desulfurization and Selective Catalytic Reduction) are effective but expensive due to the large amouth of sorbent consumed. The leading regenerable process is the NOXSO process, which wses a sodium aluminate sorbent for the simultaneous removal of NOx and SOx. Because the NOXSO sorbent has a low SOx loading, a very high sorbent circulation rate is required, causing a high parasitic power consumption, high energy requirements for sorbent regeneration, high sorbent attrition, and requireing a high capital investment.TDA Research has identified a method of increasing the SOx loading providing high particle strength, and preventing the sorbent from breaking during absorption and regeneration. The new sorbent allows them to reduce the sorben circulation rate by a factor of four, thereby reducing the parasitic power, fule consumption and capital cost, and increasing the sorbent life. Phase I will demonstrate that their sorbent can be adapted to the NOXSO process, optimize the sorbent composition, and extimate the life cost for their improved process.
