Lextran-Pollution Reduction Technology

To enable a very cost effective and versatile SOx, NOx and mercury emission control technology that can be widely implemented in the prevailing open spray tower environment to reduce any boiler’s pollutant or toxic emissions to the stringent emission standards.

Lextran is a privately held company specializing in sulfur oxide (SOx) and nitrogen oxide (NOx) catalytic pollutant removal, and mercury and other heavy metals toxics removal, in an open spray tower technology.
Lextran’s first generation catalyst has pioneered single-step simultaneous removal of sulfur dioxide (SO₂) and nitrogen oxides (NOx).
Second generation of its catalyst and reagent development resulted in a significant de-SNOx removal quality and the ability to remove simultaneously mercury (Hg) and other heavy metals emitted by the combustion plants.
Lextran's patented technology introduces a simple, multi-pollutant removal process that requires minimum equipment and only liquid reagents, as well as a relatively small footprint, and is considerably less costly in terms of investment and operation than technologies that treat each pollutant separately.
Lextran's technology either meets or substantially exceeds all international regulatory requirements, including almost complete removal of SOx, virtually complete removal of mercury; up to 95% removal of NOx and partial removal of particles. In addition, Lextran's process yields a valuable, commercial-grade fertilizer as byproduct.
Lextran's technology is applicable to different types of target customers, such as coal and heavy fuel fired power plants and industrial installations, diesel power plants, solid waste management incinerators and any other combustion plant emitting SOx, NOx or mercury.
Since all of the Lextran air-control processes are implemented in an open spray tower, the prevailing environment to De-SOx, there are several niche applications of the Lextran technology which are unique and particular to it. Namely,
- the ability to upgrade and /or retrofit existing WFGD towers to improve De-SOx removal, and/or introduce mercury control in addition to the De-SOx
- the ability to introduce a full mercury removal upstream to sea water FGD (SWFGD) and thus enable the application of this very attractive desulfurization process without releasing the mercury to the sea
- provides an elegant solution to all the small coal-fired boilers that to date are typically exempt from emission control because of economical and operational small scale considerations.
