Mobotec Systems

Mobotec USA, Inc., is exploring furnace sorbent injection using limestone or trona in combination with rotary opposed fire air (ROFA) and ROTAMIX (a second-generation SNCR and sorbent injection process) for SO2 and mercury removal. Mixing in the ROFA and ROTAMIX systems creates optimal conditions for achieving multipollutant reduction by providing ample turbulence and residence time within a specific temperature window [98]. Tests with trona and limestone have achieved reductions in SO2 of 69 and 64%, respectively; SO3, 90 and 90%; HCl, 0 and 75%; mercury, 89 and 67%; NOZ, 4 and 11%; and particulate matter, 18 and 80% [102].
