O&M Issues DSI Systems - Startup, Shutdown & Cycling Loads by Tony Licata, Licata Energy - Hot Topic Hour July 10, 2014

Tony Licata, Principal, Licata Energy & Environmental Consultants, Inc. indicated that the new regulations regarding startup and shut down emissions require utilities to meet the following challenges.  How soon can we turn or turn off on DSI and carbon systems?  Prevent deposits forming in ductwork.  Sorbent contact with acid gases/Hg at low flow conditions – mass transfer.  Does the chemistry work at lower temperatures seen during startup/shutdown?  Contact time.  Impacts on balance of plant.

Dry Sorbent Injection Panel Discussion by Paul Farber, P. Farber & Associates, LLC - Hot Topic Hour July 10, 2014

Paul Farber, Principal, P. Farber & Associates, LLC gave a good overview and was able to consolidate the basic aspects of DSI as follows:  98% reduction of SO3, H2SO4, and HCl possible with DSI  90% reduction of SO2 with DSI has been demonstrated  High percentage reduction of SO2 with DSI can result in the sorbent and reaction products entering the PM control device to be as much as the flyash loading  Where Trona or SBC is injected the collected material will have significant levels of sodium  Leachate tests of flyash/Trona/SBC mixtures have shown increased levels of metals such as selenium as well as sodium.
