Assessment of H2S Gas in Petroleum Company and Photocatalytic Degradation Using TiO2 Nanostructured Thin Films

The search applied the evaluation and risk assessment of H2S gas at Suez Oil Processing Company (Coker complex units). Different samples were measured for the Hazard H2S in many places around the Coker units in 2012. TiO2 was prepared by hydrothermal approach in presence of oleic acid. TiO2 was characterized by XRD and SEM. Treatment of the produced H2S was carried out by photocatalysis using (TiO2) phcatalyst and UV light source. The removing efficiency of H2S reaches 98% using UV lamp. The stability and the capacity of the removing were also studied. The degradation reaches 97% 96% after catalyst poisoning through three cycles.
