Modeling of Mercury Speciation and Capture in Coal-Fired Flue Gas
A 3D computational fluid dynamics (CFD) modeling tool was developed to model the mercury speciation and capture processes in coal-fired flue gas,including gaseous mercury oxidation and adsorption of mercury by the paniculate matter.This CFD modeling tool was then applied to predicting enhanced mercury oxidation and capture by HBr injection in a slipstream reactor.The reaction rate constants of the mercury oxidation by HBr are extracted from the slipstream reactor testing data from the ICSET of Western Kentucky University.The modeling results show good agreement with the testing data and reasonable trends under different conditions.This CFD modeling tool can be either used to design a new mercury control system with higher efficiency and lower operating cost or to improve the performance of an existing system.
