“…The petroleum processing industry produces a considerable amount of water at different stages, e.g., thermal cracking, distillation, and catalytic cracking, producing a large amount of wastewater.Petroleum industry wastewater contains a variety of organic and inorganic pollutants, such as sulfides, phenol, heavy metals, hydrocarbons, etc. [2,3]. The amount of wastewater produced from the petroleum refining process is estimated to be about 1.6 times that of processed crude oil [4].…”

The present work deals with the fabrication of novel poly(vinylidene fluoride) (PVDF)/Multi-wall Carbon Nanotubes (MWCNT)/Polypyrrole (PPy) ultrafiltration membrane by phase inversion technique for the removal of crude oil from refinery wastewater. In situ polymerization of pyrrole with different concentrations of MWCNT ranging from 0.025 wt.% to 0.3 wt.% in PVDF prepared solutions. Measurement of permeability, porosity, contact angle, tensile strength, zeta potential, rejection studies and morphological characterization by scanning electron microscopy (SEM) were conducted. The results showed that membrane with (0.05% MWCNT) concentration had the highest permeability flux (850 LMH/bar), about 17 folds improvement of permeability compared to pristine PVDF membrane. Moreover, membrane rejection of crude oil reached about 99.9%. The excellent performance of this nanocomposite membrane suggests that novel PVDF modification with polypyrrole had a considerable effect on permeability with high potential for use in the treatment of oily wastewater in the refinery industry.

The oil and gas industry is characterized by petrochemical industrial wastewater known basically as effluent, which typically contains various organic and inorganic components, naturally present or added during oil and gas processes. Thus, proper management or treatment is needed for reuse, discharge, or final disposal requiring complexity of the wastewater composition needing stringent discharge procedures, standards requiring combinations of treatment methods. Effluent being a complex mixture of different organic and inorganic compounds (mostly salts, minerals, gas and oils), is majorly generated during oil/gas production. The volume of effluent is increasing around the world, and as a consequence, its discharge to the environment is one of the global concerns. The various methods of effluent management have their own advantages and disadvantages when used for offshore or onshore units. However, comprehensive and deep-understanding of each issue can provide a guideline for better and more practical solutions to its management. In this work, various physical and chemical treatment methods are reviewed and the most effective recommended to proper effluent management that meets all international standard and enhances sustainability. In this study the Pre-treatment, treatment and post treatment approaches employed reduced the amount of impurities present in the effluent with varying pH of 7.2 and 7.8, COD of 30 and 60mg/L, BOD value of 45 and 54 respectively, TSS value of 80 and 60mg/L and TDS of 5200 and 4800.

“…Due to their high environmental impact, discharge limits for the concentrations of various parameters are always established in every petroleum refining industry for policy compliance [27]. Different review and research articles on PRWW including [20,[28][29][30][31] have reported the maximum concentration level (MCL) of the PRWW contaminants. Based on the reviews, the average effluent qualities reported for pH, BOD, COD, oil/grease, phenols, and total organic carbon (TOC) are 6-9, <20 mg/L, <200 mg/L, <10 mg/L, <0.25 mg/L, and <75 mg/L, respectively.…”

The treatment of petroleum refinery wastewater (PRWW) is of great interest in industrial wastewater management. This wastewater contains a diverse concentration of contaminants such as oil and grease, petroleum hydrocarbons, phenols, ammonia, and sulfides, as well as other organic and inorganic composites. Refinery wastewater treatment has been attempted through various processes, including physical, biological, chemical, and hybrid methods, which combine two or more techniques. This review aims to summarize current research studies involved in the treatment of petroleum refinery wastewater using conventional, advanced, and integrated treatment techniques. Furthermore, it critically highlights the efficiencies and major limitations of each technique and the prospects for improvements. Several conventional treatment techniques (basically, the physicochemical and biological processes) are discussed. In this context, advanced oxidation processes (AoPs), especially electrochemical oxidation and photocatalysis, as well as integrated/hybrid processes are found to be effective in removing the recalcitrant fraction of organic pollutants through their various inherent mechanisms. These techniques could effectively remove COD and phenol concentrations with an average removal efficiency exceeding 90%. Hence, the review also presents an elaborate discussion of the photocatalytic process as one of the advanced techniques and highlights some basic concepts to optimize the degradation efficiency of photocatalysts. Finally, a brief recommendation for research prospects is also presented.
