2. Successes, Opportunities, & Lessons Learned: Digested Gas ICE Cogeneration System

With aging cogeneration equipment in place and in need of replacement, the South Orange County Wastewater Authority (SOCWA)  has undergone two projects to replace the aging infrastructure and become one of the first wastewater agencies in the SCAQMD jurisdiction to comply with the new regulations. Taking on the new emissions standards meant incorporating new processes in the gas treatment and engine emission trains. The new cogeneration systems include similar lean-burn internal combustion engines to produce heat and electricity that is reused on side. The emissions controls are operated to reduce the release of nitrous oxides and volatile organic compounds into the atmosphere. We will share what went right, what went wrong, and what we’ve learned navigating the regulatory and technical difficulties throughout the installation and operation of the new cogeneration systems.
