When real estate is available, multi-point ground flare (MPGF) systems are an economical approach to smokeless combustion of large amounts of process gas. By inducing air to a large array of high-pressure burning points, smokeless combustion can be achieved with high turndown, while concealing all radiation within walls. MPGF systems provide smokeless capacity an assist medium, involve no moving parts, and require low utilities since burners are designed to crosslight, minimizing the number of pilots necessary. Moreover, MPGF systems eliminate ground level radiation through the use of walls.
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.
