First 4 ICESP conferences reported in the Mcilvained Precip Newsletter
Marilyn McIlvaine was in California for the first international conference on electrostatic precipitation in 1981. She also attended and reported on the next three conferences in Japan, Italy, and China. This series of 28 pages of articles covers the first 4 conferences. The McIlvaine Company finally became completely digital in 1999. Data on the more recent conferences is retrieved on line. Also the ICESP website has links to the papers from current conferences but not these first four.

Bromine can accumulate in the scrubber recycle. Confirmation of the accumulation was determined in a study at Lower Colorado River Authority (LCRA). John Grocki advised the attendees that there are big variations even between units at the same plant. There is a range of concentrations which can be of concern. Bromine and Chlorine cannot be treated the same and the combination has a different impact than either one independently. So whether there will be corrosion and which material is best to protect against it is based on the concentrations of both halogens. In addition to the scrubber itself, the injection of halogens in the fuel can have impacts on the air heater and ductwork.

Chemtura can supply bromine as calcium bromide or in many other forms. The company works with clients from inception through continuing operational support. Setting up calcium bromide systems is relatively easy but there is no reason to over-design and invest more than necessary or to under-design and create operational problems. Chemtura is conducting tests which show the impact of bromine in the gas and scrubbing liquor on the materials with which it may come in contact. The quantity of bromine added can vary to compensate for changes in the process e.g., changes in fuels or deterioration of the catalyst. Since activated carbon is quite expensive it makes sense to utilize bromine with the fuel to supplement the carbon under upset conditions.

This scrubber additive prevents re-emissions and creates solids which are easily separated from the FGD wastewater. GRE is successfully operating a system with this chemical at its Bismarck, ND plant. Addition of CaBr in the scrubber improves overall efficiency.

HClear™ can be injected in the duct ahead of the particulate device and removes HCl without removing SO2. It is not a sodium product and does not impact ash sales. Very high removal rates are achieved at less than 25 lbsHClear/ton of coal. There is significant value in decreasing scrubber corrosion and wastewater treatment costs.

Straightening the flow at KCP&L LaCygne Unit 1 has provided uniform flow in the SCR hood to prevent flyash accumulation. This results in reduced catalyst replacement costs and reduced vacuum removal costs for deposits, according to Reid Thomas.
