University of California System: University of California, Santa Barbara
posted on 05/23/2010
An efficient and cost-effective solution for mitigating mercury emission levels in exhaust gases.
Suggested Uses
Mitigation of Mercury Emissions in:
- Coal combustion
- Municipal and medical waste incineration
- Combustion of oil
- Metal smelters
- Cement producers
- Chloralkali process
- Gold mining activities
This technology is available for licensing. US. Patent No. 7,517,511
Advantages
- Effective method for decreasing mercury emissions
- Economically installed, operated, and maintained
Detailed Description
Researchers at the University of California, Santa Barbara, have designed an efficient solution for mitigating mercury emission levels in exhaust gases, wherein mercury dichloride is formed upon a surface from a substantial portion of the mercury in the exhaust gases. The mercury dichloride sublimes from the surface, and the sublimated mercury dichloride is removed from the exhaust stream.

Background
Currently, there is a growing concern over emissions of mercury into the atmosphere and subsequently into the food chain. As a result there has been increasing research activity with respect to this problem, particularly after the U.S. Environmental Protection Agency’s decision to regulate mercury emissions from power plants. However, all contemporary methodologies and devices have inherent deficiencies which detract from their overall effectiveness, desirability, and economical cost.
