“…Regarding the possible recovery and regeneration of the adsorbent and adsorbate in the adsorption process, it plays a prominent role as treatment options for the elimination of BTEX from the aqueous solution (Aivalioti et al 2012a). An extensive range of studies has been carried out on adsorption of BTEX from aqueous solutions by employing various adsorbents such as zeolite (Seifi et al 2011;Szala et al 2015), resins Rathilal 2017, 2018), carbon nanotube (Lu et al 2008;Su et al 2010Su et al , 2016Yu et al 2016), organoclay (Jaynes and Vance 1996;Nourmoradi et al 2012;Vianna et al 2005) and AC (Aleghafouri et al 2015;Daifullah and Girgis 2003). Li et al (2010) evaluated the application of three EG-based complex materials for removing toluene.…”

The oil and gas production is identified by consuming a large amount of water and generating massive produced water. The produced water is either reinjected into the underground layers or released into the rivers and oceans that can cause severe damage to the environment due to toxic elements such as salts, oil and grease, and polyaromatic hydrocarbons. So produced water treatment and management can reduce the significant threats to the soil and water resources and solve the lack of water in different water-consuming sectors. During the last decades, adsorption methods, such as using expanded graphite and activated carbon materials, have attracted scientists' attention because these adsorbents are cost-effective and practical. This study aimed to review expanded graphite's synthesis, adsorption process, and efficient factors in removing heavy oil, heavy metals, benzene, toluene, ethylbenzene, and xylenes, and organic acids from produced water and compare with other adsorbents, including activated carbon and residual biomass. Based on the results of extensive research works, expanded graphite's high adsorption feature suggested that graphite can be a promising adsorbent in actual produced water treatment.

“…Adsorption stands out among these technologies, because it offers flexibility, low energy requirements, and low operating costs . Activated carbon has been extensively used as adsorbent for BTX removal from water and wastewater; however, high price and regeneration cost of this material limit its further application. − Clay minerals are considered effective alternative adsorbents for the removal of organic contaminants, due to high surface area and reactivity . Promising results have been obtained for BTX removal using different types of clay minerals. , …”

Benzene, toluene, and xylene (BTX) are potential contaminants of groundwater, and there is a need to improve current remediation techniques, such as adsorption. Different materials can be applied in this process, like organoclays that have affinity for organic compounds. The aim of this work was to study BTX removal from mono-, bi-, and tricomponent solutions in a dynamic fixed bed system filled with organoclay. For the monocomponent system, using a 1.6 mmol/L adsorbate concentration, the useful removal quantities were 0.012, 0.030, and 0.140 mmol/g for benzene, toluene, and p-xylene, respectively. Based on the results, the affinity order was p-xylene > toluene > benzene. The multicomponent tests presented similar affinity tendency toward the organoclay. The mathematical model of Yan described the majority of the experimental breakthrough curves better than the model of Thomas. Partition was identified as the prevailing mechanism in BTX uptake, and the main adsorption sites were associated with the nanosized organic phases.

“…The amount of adsorbed organic chlorides, q t (mg/g) at time t , was calculated by the following equation , where C 0 is the initial concentration of the organic chloride (mg/L), C t is the concentration of the organic chloride at specified time t (mg/L), V is the volume of the naphtha fraction (L), and m is the mass of adsorbent (g). Also, the adsorption capacity of sintered γ-Al 2 O 3 nanoparticles at equilibrium condition, q e (mg/g), was calculated by the following mass balance equation − where C e is the equilibrium concentration of the organic chloride compounds in the naphtha fraction (mg/L). The removal percentage (%) of organic chloride compounds from the naphtha distillate by the adsorption process can be calculated using the following equation: , …”

Because of destructive effects of organic chlorides, elimination of these compounds from contaminated crude oil and its distillates is very crucial for oil refiners. Despite the importance of the subject, limited researches in this field are performed and most of the proposed removal methods are operationally difficult and costly. In the present study, an adsorption process as an efficient technology is proposed and employed to eliminate the organic chlorides compounds from the naphtha fraction of contaminated crude oil. The γ-Al2O3 nanoparticles as an adsorbent are prepared and characterized by XRD, SEM–EDS, and BET analyses. Adsorption experiments are carried out at different operating temperatures and also various initial organic chloride concentrations. The experimental results indicated that the adsorption efficiency reaches to more than 96%, when the initial concentration of the organic chloride in the sample is 8.5 mg/L. The adsorption equilibrium analysis revealed that the Freundlich isotherm model provided the best fit and prediction of experimental data. It was also found that, for all of the verified samples, the adsorption kinetics followed the pseudo-second-order equation well. According to experimental investigations reported in the present work, the sintered γ-Al2O3 nanoparticles would be an effective adsorbent for elimination of organic chloride as a hazardous material from the naphtha distillate of crude oil.
