Integrated with Proprietary Kinetic Chemistry Submodels

Reaction Analytic Solutions has significant modeling experience and strong capability in design and optimization of Dry Sorbent Injection (DSI) and Activated Carbon Injection (ACI) technology for pollutants removal from flue gas. In addition to Conventional CFD flow modeling, we have incorporated a number of our in-house proprietary sorbent chemistry sub-models, including:

  • Hydrated lime + SO3
  • Hydrated lime + HCl/SO2
  • Trona + HCl/SO2
  • Limestone + SO2
  • Activated carbon + Hg/HgCl2

CFD predictions of SO3 concentration and reduction percentage for a DSI system on a 450-MWe unit for 3 Cases with injection lances.

CFD model to determine injection locations and number of injections to obtain the best coverage of sorbent downstream before airheater inlet.

The following table summarizes the advantages of chemistry-based Advanced CFD modeling versus flow-only (or non-chemistry) Conventional CFD modeling, in terms of CFD outlet and evaluation capabilities. Advanced CFD model provides “real-life” predictions, including not only the mixing and flow related output that a conventional CFD can provide, but also gas species concentration and reduction predictions. Advanced CFD model approach provides a much comprehensive and useful tool for evaluating a number of important design/operating parameters as well as sorbent properties.
