“…Also, cyclohexane had high ORR values at 2:1 C/OS ratio with Triton X-114 (63% ± 3) and rhamnolipid (63% ± 2). These values are higher compared to other studies (Biceroglu 1994;Avila-Chavez et al 2007;Zubaidy and Abouelnasr 2010;Hu et al 2015;Hu et al 2017;Nezhdbahadori et al 2018). These authors reported ORR values lower than 60%.…”

“…Co-solvents are also added in the OSW to assist in the extraction of the oil (Schramm 2000 ) that has been previously demulsified by the surfactants. The rationale behind the use of a co-solvent in the oil recovery is the selective extraction of all oil components from sludge, and therefore, the miscibility of the solvent with the oil is determinant in the success of the oil extraction (Rincón et al 2005 ; Hu et al 2017 ). In addition, the solvent can repel chemical additives used in the oil industry and the dispersed particles from the oil/solvent solution.…”

Different physicochemical and biological treatments have been used to treat oil sludges, and oil recovery techniques are preferred such as oil sludge washing (OSW) with surfactants and co-solvents. Toluene is commonly used as co-solvent, but it is non-benign to the environment. This study tested alternative co-solvents (n-pentane, n-hexane, cyclohexane, and isooctane) at 1:1 and 2:1 C/OS (co-solvent to oil sludge ratio). Also, this study evaluated the effect on the oil recovery rate (ORR) of three main parameters in the washing: type, concentration, and application ratio (S/OS) of surfactants to oil sludges. To date, no study has assessed these parameters in the washing of oil sludges from different sources. Four types of oil sludges and five surfactants (Triton X-100 and X-114, Tween 80, sodium dodecyl sulphate (SDS), and rhamnolipid) were used. The results showed that cyclohexane had high ORR and could be used instead of toluene because it is more benign to the environment. The S/OS ratio had a high effect on the ORR and depended on the type of oil sludge. Rhamnolipid, Triton X-100, and Triton X-114 had the highest oil recovery rates (40 – 70%). In addition, it was found that the surfactant concentration had no effect on the ORR. Consequently, the addition of surfactant was not significantly different compared to the washing with no surfactants, except for one sludge. The use of the surfactant in the washing solution can help in the selective extraction of specific oil hydrocarbon fractions in the recovered oil to assess its potential reuse as fuel. Further recommendations were given to improve the OSW process.

“…It is recognized as hazardous waste because it can pose serious threats to the environment and human health . Up to now, many oily sludge treatment methods have been developed, including incineration, solidification, solvent extraction, ultrasonic treatment, chemical treatment, and biodegradation . Polymer flooding for the enhanced oil recovery has been widely used in Bohai oilfield in China and the partially hydrolyzed polyacrylamide (HPAM) is the most used polymer .…”

“…During the polymer flooding, many oil sludge produced from polymer flooding (OSPPF) were produced. The oil sludge studied in many reports contained a lot of inorganic solid and oil and no polymer. Different from these oil sludges, there were many polymers and a little inorganic clay in the OSPPF.…”

Usually, the treatment of oil sludge produced from polymer flooding (OSPPF) in offshore oilfield needs transport and incineration. It is time‐consuming and high‐economic cost. In this paper, firstly, the OSPPF in an offshore oilfield was analyzed by IR, SEM, EDS, and XRD and its formation mechanism was discussed. Then, chemical degradation was proposed according to the formation mechanism. Mixture of H2O2 and diethylene triamine pentacetic acid (DTPA) was chosen for the chemical degradation of OSPPF. The effects of different factors on degradation rate were studied and the national condition was obtained as follows: 3 g OSPPF, 3 g kerosene, and 9 g aqueous solutions containing 5 wt% H2O2+ DTPA (H2O2:DTPA was 1:1) were mixed at 65°C for 12 hour. After the degradation, the oil in the OSPPF can be recovered and polymer gel in the OSPPF can be destroyed completely. This chemical degradation is a good choice for treatment of OSPPF in situ.
