“…Ozone photolysis occurs when UV radiation (wavelength of 254 nm) is applied to ozone-saturated water [59]. According to Equations (21) and (22), in order to produce 1 mol of hydroxyl radical, the consumption of 1 mol of ozone and half a mol of hydrogen peroxide is required. In this system, contaminant degradation can occur due to the chemical oxidation of hydroxyl radical, the direct oxidation of ozone, as well as the photolysis caused by the UV.…”

“…Shailja Singh and Shikha [22] mentioned the primary pollutants found in the effluent from various processes in refineries. The liquid effluents generated in the oil refineries differ from one industrial plant to another due to the variation in the configuration of the plant and in particular, to the type of petroleum processed.…”

Characteristics and Treatment of Wastewater from the Mercaptan Oxidation Process: A Comprehensive Review

et al. 2020

Sulfur compounds are removed from petroleum by the addition of sodium hydroxide at a very high concentration. As a result, a residue called spent soda or spent caustic is generated, being extremely aggressive to the environment. In this work, the chemical properties of this residue are described in detail. The sodium hydroxide remains that have not reacted, sulfur compounds, and organic matter are the primary pollutants reported. Additionally, the main characteristics of the methods of treatment used to reduce them are described. This review comes from comprehensive and updated research and bibliographic analysis about the investigation on the topic. The advantages and disadvantages of the different treatment methods are highlighted. We established some criteria to set out when assessing the application of each one of these treatments is considered.

“…Refineries liquid effluents are complexes matrices of organic and inorganic pollutants, the quantitative and qualitative contamination depends on the unit configuration and the crude oil nature. The major pollutants found in the effluent are oil and greases, which are the source for other hazardous compounds such as phenols, BTEX, naphthenic acids (NA) and poly-aromatic hydrocarbons (PAH) (Fakhru'l-Razi et al 2009;Aljuboury et al 2017;Ali et al 2018;Al-Khalid & El-Naas 2018;Singh & Shikha 2019).…”

A synthetic wastewater based on Algiers refinery real effluent was prepared and treated using anodic oxidation. Full factorial plan design was used to conduct the statistical analysis of the results. The aim of the study was to assess the interaction between current density (CD) and stirring degree (SD), and quantify their effects on chemical oxygen demand (COD) removal and electric energy specific consumption (EESC). With an initial COD of 487 mg/l, pH of 5.5 and 0.05 M of Na2SO4 as supporting electrolyte, it was found that a 55 rpm steering degree variation lead to a substantial gain in COD removal and energy consumption, 6% and 8.5 KWh/kg, respectively. Current density was found to have different effect on removal efficiency within the applied stirring domain, and that mass transport coefficient (km) is inversely correlated to energy consumption. Theoretical model describing the process was reviewed and the relation between concentration, hydrodynamics and applied current was emphasized.

“…Petroleum refinery effluent (PRE) consumes large amounts of wastewater which poses an environmental risk to aquatic creatures if they are discharged without treatment. They are generated from manufacturing fuels, petrochemical, lubricant intermediates and crude oil refining processes [4]. Oil refining wastewater is polluted with hydrocarbons, phenols, suspended matter, dissolved solids, minerals and a mixture of oils [5].…”

This work aims to evaluate the treatment efficiency and feasibility of a sand filter as a post treatment for a primary treated effluent from activated sludge process (ASP) of oil refinery wastewater (ORWW) at different flow rates. There are several factors influencing the treatment efficiency of the used sand filter including; wastewater characteristics, sand media and flow rates. The treatment unit consists of opaque sand filter column fabricated from PVC material. It was fed by a primary treated effluent from ASP of ORWW. The average concentrations of raw ORWW for turbidity, Chemical oxygen demand (COD), Biological oxygen demand (BOD), Total suspended solids (TSS) and phenol were 419 NTU, 409 mgO2/L, 118 mgO2/L, 111 mg/L and 2 mg/L, respectively. The sand filter was operated at three different flow rates; 120 L/h, 240 L/h and 360 L/h. The experimental results proved that 240 L/h is the optimum flow rate. The achieved removal values at this flow rate were 79.04%, 55.82% and 63.55 for turbidity, COD and TSS, respectively. The treated permeate complies with the National Regulatory Standards for irrigation and/or safe discharge on water streams after slight disinfection.
