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.
The Enclosed Ground Flare destroys a waste stream, but does not maintain a constant temperature while doing so, simplifying the control scheme, and allowing the overall system to be more economical. These systems allow for reduced flame visibility, minimal heat and noise, real-time emissions sampling, and smokeless combustion. These flares may require supplemental assist gas streams depending on whether the process stream can sustain combustion. by ensuring proper residence time, Fully Enclosed Ground Flares attain relatively high destruction efficiencies.
