ACI for Mercury Removal

Integrated with Proprietary Kinetic Chemistry Submodels

 

RAS 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/SBC + HCl/SO2

  • Trona/SBC + SO3

  • Activated carbon + Hg/HgCl2
