University partners with Israeli company to test air pollution technology

The overall goal of this project is to determine the effectiveness of Lextran's technology for use by the company's North Dakota partner, Great River Energy

The University of North Dakota is working with Lextran Ltd., a global air pollution control company based in Petach Tikva, Israel, to test the performance of Lextran's multipollutant control technology for use in coal-fired power plants.

The university's Energy & Environmental Research Center conducted a weeklong combustion test in one of its demonstration facilities to evaluate the performance of the technology on multipollutant reduction in lignite-fired flue gas conditions.

The partnership also includes the U.S. Department of Energy (DOE), the North Dakota Industrial Commission and Great River Energy,

The overall goal of this project is to determine the effectiveness of Lextran's technology for use by the company's North Dakota partner, Great River Energy.

Lextran, a privately held company, developed the technology for combined removal of sulfur oxides and nitrogen oxides from combustion flue gases emitted from power plants and other facilities burning fossil fuels.

Each individual pollutant has required a specific control strategy, which imposes financial stress to the utility industry. Cost-effective multipollutant control technologies are needed for companies burning lignite to meet anticipated future regulations.

Although demonstrated previously, this technology has not been evaluated specifically in a North Dakota power plant or in a North Dakota lignite flue gas stream.

The total cost of the project is more than $195,000 and was completed in March 2013. The EERC will now work with Lextran to pursue a consortium-based initiative to test the technology further in a full-scale field demonstration.
