ClearSign demonstration recommended for major refiner

ClearSign Combustion Corporation has announced that the Technology Committee of the South Coast Air Quality Management District (SCAQMD) unanimously approved the recommendation of staff that ClearSign's Duplex technology be demonstrated at a major refinery in Southern California.

SCAQMD staff cited their support for the effort as a means of improving air emissions without the use of harmful chemicals and reagents, which are required in selective catalytic reduction (SCR) for control of oxides of nitrogen (NOx), a criteria pollutant that is a precursor to photochemical smog.

SCR is currently state-of-the-art in pollution control equipment and is designated as a best available control technology. The board will consider the request at their next meeting on 1 September 2017. If approved, the demonstration will occur at a Southern California refinery on an industrial boiler. It will involve the demonstration of ClearSign's Duplex technology within the customer's operations.

ClearSign's Chairman and CEO, Stephen Pirnat stated, "The California regulator's recognition of the tremendous potential for ClearSign technology to dramatically reduce emissions and the associated costs to improve air quality is very encouraging to the engineers and scientists at ClearSign, who have worked diligently to develop this game changing technology."
