APPLICATION OF A NEW SORBENT FOR CONTROL OF SO2 AND NOX EMISSIONS FROM EXISTING AIR FORCE FIXED SOURCES

SANITECH ENGINEERS HAVE DEVELOPED A NEW CLASS OF SORBENTS THAT VERY EFFECTIVELY REMOVES SO2 AND NOX FROM GASES EXHAUSTED FROM EXISTING FIXED SOURCES. THE NEW SORBENTS ARE A COMPOSITE MATERIAL, CONSISTING OF A LOW-COST MINERAL OXIDE, MGO OR CAO, BONDED TO AND REACTED WITH A LOW-COST EXPANDED SILICATE CARRIER, VERMICULITE OR PERLITE. THE MATERIALS POSSESS SOME VERY UNIQUE AND DESIRABLE PROPERTIES. THEIR VERY LARGE SURFACE AREAS PERMIT HIGH OXIDE LOADINGS, AND THE MATERIALS APPEAR TO BE CATALYTIC AND SUPER-REACTIVE. THEY ARE RELATIVELY STRONG, CAN BE USED DRY OR MOIST, AND PERFORM WELL AT TYPICAL PRE-STACK GAS TEMPERATURES. IMPORTANTLY, CERTAIN COMPOSITIONS ARE READILY REGENERABLE AT LOW TEMPERATURE BY HEATING ALONE. TYPICALLY, THE SORBENTS REMOVE 99% OF THE SO2, 90-PLUS % REMOVAL OF THE NO APPEARS POSSIBLE. AN OPTIMUM METHOD OF USING THE NEW SORBENT IS NEEDED. THE PROPOSED RESEARCH INVOLVES ATTEMPTING TO DEVELOP SUCH A METHOD. USE OF THE SORBENT AS A SIMPLE INJECTION INTO THE FLUE GAS DUCT WILL BE INVESTIGATED. THE PROPOSED RESEARCH WILL ALSO INCLUDE AN EVALUATION OF THE NOVEL PROCESS MODIFICATION TO ENHANCE NO REMOVAL.
