SEATTLE, July 13, 2017 /PRNewswire/ -- ClearSign Combustion Corporation (NASDAQ: CLIR), a leading provider of industrial combustion technologies that deliver unmatched reduction of pollutant emissions while improving operational costs, today announced that they have received a purchase order to qualify the company's revolutionary Duplex™ combustion technology as a precursor to an installation at a super major oil refinery.  

Qualification testing will occur at ClearSign's facility in Seattle, WA and involves evaluating the company's Duplex technology under a variety of fuel compositions and process conditions that mirror the customer's operations. The global oil giant is funding the testing to determine Duplex's suitability for a variety of refinery process heaters and conditions in a test expected to conclude later this year. The customer plans to continue testing at one of the oil giant's refineries. Following this qualification, the customer has indicated interest in standardizing the Duplex technology to existing heaters within the US and abroad where the Duplex platform is suited for deployment.  

ClearSign's Chairman and CEO, Stephen Pirnat stated, "Our Duplex technology has been proven to the extent that a global supermajor refiner is willing to pay for qualification. This is substantial validation of the hard working scientists and engineers at ClearSign that have worked diligently to create game-changing technology that solves difficult air pollution problems in a cost-effective manner."
