“…Monoethylene glycol (MEG; formula HO-CH 2 -CH 2 -OH) is an essential chemical product used to manufacture polyester fiber, bottles, and film [2]. It is also required to reduce the risk of gas hydrate formation during hydrocarbon transportation [3]. Petrochemical industrial wastewater laden with MEG is characterized by poor biodegradability, high toxicity, and carcinogenicity [4].…”

“…The long hydraulic residence time leads to large reactor volumes and initial investment costs [8]. Moreover, the chemical treatment of petroleum wastewater requires advanced reactions and processes, and it utilizes large amounts of reagent and raw material [3]. Furthermore, the membrane technology suffers from high energy consumption, fouling and scaling problems, and complex production and control procedures [11].…”

In this study, the pyrolysis of sewage sludge was employed to prepare a biochar (BC) adsorbent that was modified using eggshell wastes, obtaining eggshell-modified biochar (EMBC). The adsorbent material was used for the removal of monoethylene glycol (MEG) from aqueous solutions under various adsorption conditions. Results showed that the specific surface area of EMBC (i.e., 3.95 m 2 /g) was approximately twofold higher than that of BC, implying that the application of eggshell waste would improve the surface adsorption performance. The optimum adsorption pH value was 7, achieving MEG removal efficiencies of 29.9% for BC and 89.9% for EMBC using adsorbent dosage = 2 g/L, initial MEG concentration = 100 mg/L, and 25 °C within 60 min. The adsorption mechanisms were illustrated regarding XRD, FTIR, and SEM, demonstrating that surface adsorption, pore-filling, precipitation, and complexation contributed to the adsorption process. The adsorption data fitted well to the Langmuir isotherm model with the maximum monolayer adsorption capacity of 12.20 mg/g, implying a reversible physisorption mechanism. Based on a techno-economic feasibility assessment, the preparation of BC and EMBC adsorbents for the treatment of 1 m 3 of wastewater-containing ethylene glycol would require capital costs of 4.80 and 6.50 US$, respectively. The selling of adsorbents and the economic benefit of tertiary treated water showed adequate annual profitability with payback periods of 12.97 and 6.79 years for the BC and EMBC scenarios, respectively. Hence, the study succeeded in preparing efficient and low-cost adsorbents that could be used for the tertiary treatment of petrochemical industrial wastewater containing toxic environmental pollutants.

“…The release of untreated oily wastewater can affect the quality of groundwater, seawater, and drinking water, and causes air pollution with the evaporation of volatile oil components to the atmosphere [4,5]. Even when released at very low concentrations, oil contaminants can have a significant impact on the environment [3,[6][7][8].…”

A Review of the Processes Associated with the Removal of Oil in Water Pollution

2021

Water plays an essential role in production and refining processes. Many industries that use petrochemicals also require water, especially for cleaning purposes. The wastewaters released by these processes are often rich in petroleum pollutants, which requires significant treatment prior to disposal. The presence of petroleum contaminants in rivers and oceans is a significant threat to human health, as well as to many animal species. A current challenge for most industries and conventional effluent treatment plants is compliance with accepted disposal standards for oil-polluted wastewater. Of particular importance is the processing of dispersed oil in water, as well as oil in water emulsion. Conventional oil and water separation methods for processing oil in water contamination have several technology gaps in terms of applicability and efficiency. The removal and effective processing of dispersed oil and emulsions from oily wastewater is a costly and significant problem. The objective of this paper is to provide a review of the principles associated with oil in water emulsion separation, with the aim of providing a more definitive understanding of the terminology, processes, and methodologies, which will assist the development of a more efficient, innovative and environmentally friendly process for the separation of oily wastewater.

“…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.
