Yougen Kong, P.E., Ph.D., Technical Development Manager at Solvay Chemicals, Inc., explained that trona can achieve up to 98 percent HCl removal while sodium bicarbonate can achieve over 99 percent while also achieving better than 90 percent SO2 removal. There is a modest price penalty for the sodium bicarbonate. On the other hand, injection avoids major capital cost and is effective over a range of 275°F to 1500°F. Bicarbonate is being used at many waste incinerators in Europe and coal-fired power plants in the US.

Mike Schantz, Director of New Business Development at Lhoist / Chemical Lime Company, explained that all hydrated lime is not the same. Sorbacal SP performs much better than typical hydrated lime on HCl. Sources using Sorbacal injection should be able to meet the 3 ppm HCl anticipated limit providing temperature, moisture, competing acid gases (SO3 and HF) and CO2 are within the normal range.

Carroll "Mack" W. McGuffey III, Associate at Troutman Sanders LLP, told the participants that it is unlikely that the final rule will be delayed by lawsuits. The litigants can petition to stay the rule until the litigation is complete but the D.C. Circuit Court is unlikely to do so. So the clock will be ticking and compliance will be required in 2014. The lawsuits can focus on several issues. One is the lack of five or more sources achieving the limits on any one pollutant. Another is the argument that a source which achieves the limit on one pollutant but not another is not a valid example.
