Method and Devices for Mitigating Mercury Emissions in Exhaust Gases
Tech ID: 20889 / UC Case 2003-257-0
Brief Description
An efficient and cost-effective solution for mitigating mercury emission levels in exhaust gases.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.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.Advantages
- Effective method for decreasing mercury emissions
- Economically installed, operated, and maintained
Applications
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
