Catalytic Products International (CPI) installed a Direct Fired Thermal Oxidizer (DFTO) at a publicly owned wastewater treatment facility for the abatement of Volatile Organic Compounds (VOCs), hydrogen sulfide (H2S), and other separated constituents from the wastewater treatment gas separation process. This project was initiated to generate Renewable Natural Gas (RNG) which can be injected into the local distribution network, while reducing emissions from the existing WWTP facility.
