The objective of the 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.”
