ENV-08-036 Advances in FCC Emissions Reduction Additives And Their Role in Implementing EPA Consent Decrees

Description:

EPA Consent Decrees negotiated with many US refiners require reductions in SO2 and NOx emissions from refinery Fluid Catalytic Cracking (FCC) units. Depending on the negotiated settlement, the refiner may be required to implement hardware solutions, additive solutions or a combination of both to achieve the agreed upon emissions reductions. Additive-based solutions to SO2 and NOx emissions reductions help refiners avoid expensive capital projects such as construction of wet-gas scrubbers or Selective Catalytic Reduction (SCR) units. Recent advances in FCC additives make their use to meet emissions limits viable for more refiners. This paper examines the advances made in FCC emissions reduction additives and the implications of these advances on the implementation of EPA Consent Decrees.
