ClearSign Announces Agreement to Install Duplex Technology in Third Oil & Gas Operation

SEATTLE, Jan. 22, 2015 /PRNewswire/ -- ClearSign Combustion Corporation CLIR, an emerging leader in combustion and emissions control technology for industrial, commercial and utility markets, announced today the signing of a field validation agreement with a California-based refinery to retrofit a three-burner, 12 MMBtu/hr process heater with its proprietary Duplex™ technology.

The agreement comes in the wake of last week's announcement of a field validation with Tricor Refining, LLC to retrofit a 15 MMBtu/hr vertical cylindrical heater.

ClearSign is also conducting continuous operation testing of Duplex technology in a 62.5 MMBtu/hr steam generator operated by Aera Energy LLC. While additional testing is ongoing, ClearSign reports that tests below the maximum firing rate have yielded encouraging results including NOx emissions that satisfy the San Joaquin Valley Air Quality Management District's Rule 4320.

The new refinery customer, announced today, selected ClearSign's Duplex technology for its unique ability to safely and cost-effectively lower NOx emissions to below 6 PPM in southern California -- a region with among the most stringent air quality standards in the world -- without the need for more expensive flue gas recirculation (FGR) or selective catalytic reduction (SCR) after-treatment. Unlike current ultra-low NOx burners, ClearSign's Duplex technology achieves this emissions performance without the potential limits to furnace capacity.

"This agreement is another example of the increasing demand for ClearSign's transformative Duplex technology and its unique ability to solve the critical environmental and operational challenges our refinery customers are facing," said Stephen Pirnat, CEO of ClearSign.

ClearSign will again collaborate in this project with Advanced Combustion and Process Controls, Inc., who will oversee the installation.
