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)

This study by Sargent & Lundy provides methods to determine costs of DSI for acid gas removal. The sorbent requirement is a function of particle size, particulate control device, and other factors. 2016 cost factors are utilized. Based on commercial testing, removal efficiencies with DSI are limited by the particulate capture device employed. Trona, when captured in an ESP, typically removes 40 to 50% of SO2 without an increase in particulate emissions, whereas hydrated lime may remove an even lower percentage of SO2. A baghouse used with sodium-based sorbents generally achieves a higher SO2 removal efficiency (70 to 90%) than that of an ESP. DSI technology, however, should not be applied to fuels with sulfur content greater than 2 lb SO2/MMBtu.

IAC Capabilities including DSI
This analysis reviews the various different sorbents and their effectivenesss on specific pollutants such as SO2, HCl, and mercury. IAC has a testing fleet to determine the correct sorbent and amount which will be needed with the DSI approach as opposed to more capital intensive options. With DSI the reagent cost is a more significant percentage of the total, so precisely predicting the reagent needs is very valuable. Various construction capabilities of large filters and transload systems are also covered.

Trona removes SO3 ahead of ESP at AEP Gavin
Trona T200 removed SO3 while conditioning the Gavin Plant ESP. T200 can used on a commercial scale to provide a reliable and cost effective SO3 mitigation technology. T200 is used year around to condition the ESP. T200 under most conditions can be injected into the ducts providing a trouble free SO3 mitigation process.

IAC supplied hydrated lime delivery system at Big Rivers as reported in FF NL -2014
At Big Rivers, IAC is working with Babcock on the DSI system and is furnishing the silo and hydrated lime delivery system. IAC is providing material handling for a large DRI plant and is including all the dust collectors for the iron dust and the high temperature collector for the EAF. A big application for the company is the handling and separating of sand used for fracking.

95% SO2 removal with DSI, SDA combination
The EUEC paper by Gerald Hunt of Lhoist demonstrates that with SORBOCAL, a high surface lime hydrate it is possible to achieve 95% SO2 removal with a combination of SDA, Cyclone, DSI , and fabric filter. DSI can be used in varying quantities and locations to achieve the needed SO2 removal to meet MATS and MACT

Improving ESP Performance Webinar - Hot Topic Hour January 20, 2010
ESP Performance Improvement can be Substantial - Hot Topic Conclusion on January 20 There has been lots of focus on replacing ESPs with baghouses to meet upcoming regulations. The speakers in the Hot Topic Hour yesterday said there is an alternative. You can upgrade existing ESPs and achieve results which may satisfy future requirements. Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., told the attendees that “there is a better alternative to SO3 for conditioning electrostatic precipitators.” Trona addition system is simple and its capital cost is much lower than that of a SO3 production and injection system. Trona is relatively inexpensive and can be injected in several places. Mick Chambers, Southern Environmental, Inc, said that you can upgrade your ESP and with halogen-based additives in the coal, you can meet the particulate and mercury regulations. He showed that the SCA of recent installations has been relatively low and yet the performance high. So the footprint of a retrofit does not have to be large. When asked about the wet ESP using a fabric for the collection plate, Mick said that it is a good option and successful on industrial boilers and process applications. We were sorry to learn that John Caine passed away in a tractor accident last September. John had represented SEI in several of our previous Hot Topic Hours and has long been a contributor to the industry. Steve Jaasund, Manager Geoenergy Division A. H. Lundberg Associates, made a case for adding a wet ESP after the FGD system to meet the upcoming MACT regulations. In the discussion period it was speculated that the new mass monitoring requirements would make it more difficult for dry ESPs to meet emission limits. The wet ESP will eliminate the exceedance spikes associated with a stand-alone dry ESP. Paul Leanza of Pollution Control Services, Inc. indicated that many utilities have the opportunity to greatly improve performance of their existing precipitators. He indicated that 50 percent of the emissions occur during rapping (rapping reentrainment). These particles are relatively large and do not cause opacity spikes proportional to the mass increase. It was speculated that with mass monitoring this phenomenon will be an unpleasant surprise. Emissions will be higher with mass monitors than they were thought to be with opacity monitors and periodic stack testing. Ron Landreth of Albemarle was pleased to find that their brominated PAC actually improves precipitator performance whereas the non-brominated PAC may add to emissions. So it is worth considering brominated PAC to capture mercury and reduce particulate. Jean Bustard of ADA-ES (ADA Environmental Solutions LLC) related experience with a proprietary conditioning chemical which has performed well and does not impact mercury capture with PAC. The company offers another approach to conditioning hot side precipitators.

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.
