Over the last 10 years, mercury emissions from fossil fuel power plants have become a significant regulatory concern globally. Even though the laws governing these emissions have been in flux, it is clear that plants taking a proactive approach to emissions reduction will reduce their long term risk and exposure to regulatory action.
Most mercury capture systems rely on contact between the flue gas and solid sorbent particles. Optimizing this contact depends heavily on sorbent injection lance design, number and location as well as the sorbent and flue gas flow distributions. Alden specializes in optimizing site-specific unit performance through computational and reduced scale physical modeling of site specific unit geometry. This modeling includes not only the gas phase, but also the solid sorbent phase. Using such studies, Alden develops flow controls and determines lance placement in the model that ensures maximum capture efficiency.
Our long history of experience in doing this work for other fossil fuel air pollution control equipment make us an ideal choice for your partner as your plant tackles the challenge of mercury capture.
