Methods of treating oily sludge: A review on current trends
Oily sludge is a highly stable water-in-oil (O/W) and oil-in-water (W/O) emulsions that are mainly generated during the refinery and production of petroleum industries. This hazardous scheduled waste contains crude oil, water, solid particles, heavy metals, and heteroatoms.
Technologies with oil recovery aim separating oil fractions either in liquid and/or gaseous forms. These include solvent extraction, centrifugation, surfactant enhanced oil recovery, and pyrolysis. 3.1.1. Solvent extraction. The principle for solvent extraction involves mixing of the oily wastes with a solvent to ensure complete miscibility.
Characterization and treatment of oily sludge: A systematic
Currently, approximately 73% of China's crude oil relies on imports, and each ton of oily sludge can yield an extraction of crude oil ranging from 0.15 to 0.5 tons. Therefore, resource-efficient treatment of oily sludge holds significant practical importance (Wang et al., 2021b). Consequently, untreated oily sludge not only generates
The solvent extraction method extracts the crude oil by using a suitable extracting agent and then separates the extracting agent and the oil substance by distillation, thereby achieving the purpose of separating the oil, water, and mud (Mansur et al. 2016; Al-Doury 2019). The primary advantages of solvent extraction are easy operation, high
Oil sludge washing with surfactants and co-solvents: oil
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
Addition of surfactants and extraction solvent could enhance the oil recovery performance of flotation. Al-Otoom et al. [158] applied a modified fluidized flotation process for bitumen recovery from tar sand, and the maximum bitumen recovery could reach 86 wt.% when 0.35 wt.% light cycle oil was added as an extraction solvent at 80 °C.
Treatment of oily sludge using solvent extraction: Petroleum
The aim of the present work is to treat this oily sludge by solvent extraction in order to separate this sludge to many components that are easy to deal with and recover the valuable crude oil. Different solvents types are used in this work: light naphtha, heavy naphtha, kerosene, gasoline, and methyle ethyle keton.
The greatest oil recovery rate was achieved with a 4:1 solvent-to-sludge ratio, and a 30-min extraction period was enhanced by 50.98% and about 60.98% of crude oil could be recovered. In another study, Zhang et al. ( 2012 ) combined the method of ultrasound-freeze/thaw treatment to treat a tank bottom sludge and the three-phase separation
Oil sludge washing with surfactants and co-solvents: oil
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
Kam (2001) used three different treatment processes for petroleum-based. sludge: sonication, extraction, an d thermal desorption. All three processes recovered simila r amounts of lighter
- What solvent is used for oily sludge removal?
- (Hu et al. 2013). In this context, many different solvents have been reported for treating oily sludge (Gazineu et al. 2005). Turpentine oil was used as a solvent to the oil removal, and it was discovered that the extracted oil accounted for 13¨C53% of the initial mass of the sludge.
- Can ultrasonic extraction recover crude oil from oily sludge?
- Hu et al. ( 2016) used ultrasonic extraction to recover crude oil from oily sludge from an oil refinery. Studies have shown that the solvent type, the solvent to sludge mass ratio, and the operating time have an important impact on the recovery of oil by ultrasonic-assisted extraction.
- Which solvent is used to extract sludge?
- The effects of different solvents (e.g. methyl ethyl ketone (MEK), naphtha, petrol and kerosene), SMs (Dowfax and sodium thiosulfate), extraction time (10¨C20 min), extraction temperatures (20¨C60 °C) and CEA/sludge ratios (1¨C4) on the extraction performance were investigated.
- How does the petroleum industry generate sludge?
- The petroleum industry generates huge amounts of oily sludge waste during different steps of oil treatment such as mining, transportation, storage and refine treatments ( Hu et al., 2015; Zhao et al., 2020 ).
