Regenerative Thermal Oxidizers (RTO) are waste gas incinerators that employ multiple beds of ceramic media that absorb heat from the exhaust gas and use this captured heat to preheat the incoming process streams. RTO’s are often used in applications such as at paint booths, printing mills, and paper mills which produce low VOC concentrations in relatively higher flow rates. This technology eliminates these streams in a highly efficient and cost effective manner while minimizing the need for fuel gas. Moreover, they can acheive ~99% destruction efficiency with 95% heat recovery.
Hydrogen sulfide or H2S is a lethal gas generated in refineries, petrochemical plants, and gas handling facilities. Sulfur recovery units produce tail gas that contain relatively substantial amounts of H2S. Flare Industries designs a special type of thermal oxidizer, designed to eliminate the H2S components, while inhibiting the creation of corrosive acid by-products. Systems of this nature typically include dispersion stacks in efforts to disperse trace H2S and SO2 particles. These highly efficient systems significantly reducing the impact of environmentally offensive compounds.
