Oxidative destruction of monocyclic and polycyclic aromatic hydrocarbon (PAH) contaminants in sulfur recovery units

The requirement of low sulfur content in fuels and the stringent environmental regulations has led to an increased production of acid gas (H2S and CO2) as byproducts in oil and gas industry. Consequently, the need for economic and efficient treatment of acid gas has surfaced. Sulfur recovery units (SRU), consisting of a furnace and catalytic reactors, are widely deployed to recover sulfur and thermal energy from acid gas. The contaminants in...
