TREATMENT OF PETROLEUM REFINERY WASTEWATER USING HETEROGENEOUS CATALYSIS WITH SERIES LaxSr1-xCoO3 PEROVKSITES

Abstract

Due to the increased worldwide energy consumption, which is expected to increase by 44% over the following twenty years (Doggett and Rascoe, 2009), the treatment of petroleum, which is an intricate combination of organic fluid called natural gas and crude oil, as well as the creation of petroleum wastewater, are major issues. The treatment of wastewater from petroleum industry is a major topic in engineering fields related to environment. The handling of petroleum and petrochemical waste is an important topic of discussion. These effluents are challenging to remediate because of the high oil concentrations. The refinery wastewater's effluent composition is based on the crude quality. According to the scenario, it differs (Benyahia et al. 2006). In the processing plant, nonhydrocarbon materials are eliminated, and the crude oil is divided into its constituent parts and combined to create useful products. Because of this, oil refineries produce large amounts of wastewater, involving oil reservoir-generated water that comes to the surface amid the drilling process. This wastewater frequently contains recalcitrant chemicals, in addition, it is highly contaminated with organic materials, which makes biological treatment challenging (Vendramel S. et al., 2015; Rasheed et al., 2011). The elimination of industrial operations' contaminants is necessary for water reuse and to comply with environmental requirements.
