ClearSign Announces Installation and Operation of Duplex™ Technology at California Refinery

SEATTLE, Aug. 11, 2015 /PRNewswire/ -- ClearSign Combustion Corporation CLIR announced today that it has successfully completed the initial installation of its Duplex™ technology in a multiple-burner, vertical-cylindrical production process heater at a California refinery. As previously announced, successful demonstration of Duplex at this facility will allow the refinery to meet strict environmental regulations for emissions of nitrogen oxides (NOx) and carbon monoxide (CO) in a cost-effective manner.

ClearSign and the customer are encouraged by the preliminary results achieved to date, which have shown a significant reduction in NOx emissions without the use of flue gas recirculation (FGR) or selective catalytic reduction (SCR). Additional testing leading to optimization of the technology will continue in order to reach the stated objectives of 6 ppm NOx, corrected to 3% O2.

The installation was completed within the customer's allotted downtime period and was promptly returned to full production while testing continues.
