ExxonMobil, ClearSign successfully complete tests of Duplex technology

ClearSign Combustion Corporation, an emerging leader in industrial combustion technologies that reduces pollutant emissions while improving operational costs, today announced that it successfully completed evaluation of its Duplex™ Technology in a comprehensive set of qualification tests for ExxonMobil.  The purchase order to conduct the qualification tests was first announced last July 13, 2017.
 
The objective of the Duplex qualification tests was to demonstrate the technology's ultra-low NOx emissions and operability limits to assess its potential application across ExxonMobil's process heater fleet.  Towards this end, ExxonMobil requested an evaluation over a broad range of typical conditions, including variations in fuel heating values, turndown, and excess air.

Stephen Pirnat, ClearSign's Chairman and CEO, stated, "We are very pleased to achieve this milestone in the demonstration of Duplex technology for ExxonMobil. It represents a critical step in the validation and rapid deployment of the technology in process heaters.  We look forward to supporting ExxonMobil's continued evaluation of the Duplex™ Technology."
