Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., discussed dry injection of Trona or sodium bicarbonate, a low-cost solution to meet the SO2 and HCl limits in CSAPR, Utility MACT and Boiler MACT. Both Trona and Sodium bicarbonate are effective in reducing SO2 and HCl. Trona is slower to react and therefore less effective on SO2 but possibly better if all you want is HCl removal. Lots of the bicarbonate will be tied up in SO2 removal. So if you want to just remove HCl Trona may be the answer.

A better alternative to SO3 for conditioning electrostatic precipitators. The trona addition system is simple and its capital cost is much lower than that of a SO3 production and injection system.

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.

Yougen Kong, P.E., Ph.D., Technical Development Manager at Solvay Chemicals, Inc., explained that trona can achieve up to 98 percent HCl removal while sodium bicarbonate can achieve over 99 percent while also achieving better than 90 percent SO2 removal. There is a modest price penalty for the sodium bicarbonate. On the other hand, injection avoids major capital cost and is effective over a range of 275°F to 1500°F. Bicarbonate is being used at many waste incinerators in Europe and coal-fired power plants in the US.

Industrial MACT Webinar - Hot Topic Hour November 18, 2010 - Part 1
Sodium Bicarbonate, Lime, CDS and Regulations were among the Topics covered on the First Day of the Industrial MACT Webinar. In 60 days or so we will know the specific changes for the final Industrial MACT. Correction-- we will know what is final until it is changed again. Unfortunately it will be three more years to find out if litigants are successful in causing changes. However, it will take three years to install the equipment and run it long enough to make sure of compliance. So it would seem there are two choices. Litigate and gamble you won’t have to shut down your plant or go ahead with the assumption that the rule will stand. Password: hth107
