I am currently a PhD student under the supervision of Prof. Clack. I received my Masters degree from IIT on July 2007 in the Mechanical, Materials, and Aerospace Engineering Department. My Phd research project is based on measuring gas-particle mass transfer within a powdered sorbent-laden jet. The use of this configuration is extremely common in full-scale mercury emissions control processes as a means of introducing a powdered sorbent into the flue gas that subsequently adsorbs (physically or chemically) or facilitates in the oxidation of the mercury in the flue gas. However, such configurations rely on conventional jet mixing processes which result in highly nonuniform distributions of species concentration and particle number density. The evolution of these concentration gradients in the turbulent, particle-laden jet, along with the concurrent adsorption and oxidation of mercury by the suspended sorbent particles, results in a complex amalgam of fluid, thermal, and chemical processes. In order to better understand these interacting phenomena, this fundamental research seeks to replicate the jet mixing dynamics that occur during full-scale sorbent injection at CFPPs. Using acetone vapor as a tracer gas and a surrogate for mercury, acetone concentration fields throughout the sorbent-laden jet can be visualized by irradiating the jet with a planar sheet of UV (266 nm) laser light, a technique call planar laser-induced fluorescence (PLIF). PLIF-generated images of the acetone fluorescence fields in the particle-laden jet can then be converted into acetone concentration fields according to predetermined fluorescence intensity-concentration correlations, thereby providing insight into the mass transfer (and removal) of the acetone tracer gas during the jet mixing process.
