CFD-based Modeling of Inflight Mercury Capture

PDF Version Also Available for Download.

Description

A numerical model of sorbent injection and in-flight mercury capture is presented. There are few existing models of mercury capture, and these typically make gross assumptions of plug gas flow, no velocity slip between particle and gas phase, and uniform sorbent dispersion. All of these assumptions are overcome with the current model, which combines the physics of mass transfer at the microscopic sorbent scale with macroscopic flow conditions provided via Computational Fluid Dynamics (CFD) simulations. The implication is a cost-efficient tool for design of injection systems that maximize capture efficiency. The modeling framework will be presented along with results based ... continued below
