Abatement of oil residues from produced water using a thermocatalytic packed bed reactor

Produced water is a major waste and environmental concern in the oil gas industry, since it contains dispersed dissolved compounds, which may harm aquatic environment. Thus, focus on offshore treatment of produced required. Current methods include hydrocyclones clarifiers that cannot achieve full abatement oily contaminants. Here we propose novel thermocatalytic degradation using thermocatalyst, namely Sr 0.85 Ce 0.15 FeO 3 perovskite benefits from thermal energy contained water, has temperatures 40–50 °C when reaching cleaning phase. It found removed faster with higher concentrations, initial removal mainly adsorption to surface followed by catalytic degradation. Based batch testing, lab-scale packed bed reactor (PBR) modelled showing can be continuously sufficient residence time reactor. • Degradation synthetic thermocatalyst investigated. Oil catalyst A dimensioned for continuous removal. ensuring
