The analysis revealed that in ONG operation, upstream operations involving gas flaring (benzene: 0.115 ± 0.1 ppmv, toluene: 0.029 ± 0.001 ppmv, ethylbenzene: 0.002 ± 0.001 ppmv, xylene: 0.123 ± 0.001 ppmv) contributed to relatively lower concentration of BTEX emission....
This gas occurs when sulfate (SO 4 ) dissolved in water is transformed to H 2 S by bacteria in the presence of organic matter. The organic matter may be present as solid material or, more commonly, as dissolved organic carbon (DOC). Seasonal variations of the presence of H 2 S may ...
