Mississippi Lime Presentation 2017: Targeted DSI Improvements
Curt Biehn of Mississippi Lime made this presentation in 2017 which shows the following list of targeted DSI improvement: (1) Reduce scale and plugs, (2) Optimize distribution for O&M benefits, (3) Reduce minimum operating temperature requirement, (4) use prior to wet scrubbing for selenium and HCl removal ( SO3 was not listed but would be another in this category)

Shiaw Tseng, Marketing Manager at Graymont, Inc., described a multi-pollutant control system for existing coal-fired power plants using lime-based Circulating Dry Scrubbers (CDS) to remove SO2, SO3, HCl, and HF. He presented the results of performance guarantee tests conducted at the AES Greenidge Station Unit #4 (107 MW) burning eastern bituminous coal (2.5 to 3 percent sulfur) with a CDS and baghouse. These tests showed pretty impressive reductions of SO2, SO3, Hg and HCl to levels that were well under the limits in the proposed utility MACT. Advantages of this system include a relatively small footprint, fuel flexibility (including biomass), low water consumption and dry byproducts (no wet sludge). Interestingly, the CDS system achieved better mercury reduction than using ACI under the same operating conditions, indicating that ACI is not required. These systems are currently operating at 14 plants in the U.S.

David W. South, Manager of Business Development at Amerex, drew from a considerable bank of experience the company has gained with some 50 MACT related boiler installations in the last five years. One unit on a PC boiler with carbon injection and a fabric filter is using 2.2 lbs/MMacf of B-PAC. Inlet mercury is 20 lbs/TBtu versus 2.5 lbs/TBtu on the outlet. Another with only 2.0 lbs/MMacf is reducing mercury from 25 lbs/TBtu to less than 2 lbs/TBtu.
