This project, which was previously announced in September 2017, will demonstrate ClearSign's Duplex technology as a best available control technology (BACT) candidate to achieve ultra-low emissions levels in refinery process heaters and other types of fired equipment. The project will involve retrofit installation of ClearSign's Duplex technology within World Oil Refinery's South Gate, California refinery as a demonstration of the technology for the District. Funding for the project is a collaborative effort that includes contributions from the air district, ClearSign, and World Oil Refinery. The addition of World Oil to the project is subject to final review and approval by SCAQMD Board of Directors, after which the project is slated to span approximately one year.

"We are extremely pleased that World Oil Refining has agreed to work with ClearSign on the previously approved SCAQMD-funded demonstration project. This project shows the commitment of all parties to evaluate best available technologies to improve air quality in the Los Angeles basin and should position ClearSign's Duplex technology as the clear choice to reduce emissions," said Steve Pirnat, CEO of ClearSign.
