Title: Particulate emission reduction using additives

Abstract

A particulate emission reduction study using a large industrial combustion turbine was undertaken. With heavy oil, both the mass particulate rate and smoke emissions exceeded original emission projections. Extensive particulate (gravimetric) emission tests were conducted to define the problem, and to assess specific corrective actions. Physical characterization of the particulate emissions revealed that the particulates from heavy oil were much larger than those found from lighter distillates. A review of the available literature on the subject was undertaken. Methods that were found to be effective at reducing smoke emissions were selected as a starting point. From this information, various techniques, including water injection, emulsification, and additive injection were evaluated to address both the visible smoke emissions and the particulate emission. Only the use of metal based fuel additives was found to be effective in reducing both visible smoke emissions and particulates. From vendor information, different additive time was selected for evaluation. Because of the complex chemistry of the fuel and additive mixtures, the vendor was required to optimize the additive carrier. Additives reduced particulates produced from the burning of heavy oil, but were found to be relatively ineffective with lighter distillate oils. Extensive chemical and physical characterization of the particulatesmore » were undertaken. From heavy oil, the particulates were found to be physically larger, greater than 5 microns. The additive was most effective on the heavy oils, but did not appear to alter the particulate size distribution. Additives did not appear to have any impact on the conversion of fuel bond sulfur into sulfuric acid mist. Additive dosage ratios were found which reduced the total particulate emission signature to meet current environmental requirements, while also nearly eliminating the plume visibility issues.« less
