A review of the application of different treatment processes
Oily sludge contains high concentrations of total petroleum hydrocarbons and heavy metals, which seriously impact the environment and human health. How to dispose of and use the oily sludge has attracted an increasing amount of attention. This study introduces harmless and resource-based oily sludge treatment technologies. It summarizes the technologies from various aspects, such as the
In the petroleum sector, the generation of oily sludge is an unavoidable byproduct, necessitating the development of efficient treatment strategies for both economic gain and the mitigation of negative environmental impacts. The intricate composition of oily sludge poses a formidable challenge, as existing treatment methodologies frequently fall short of achieving baseline disposal criteria
Petroleum sludge treatment and disposal techniques: a review
Petroleum sludge is a solid emulsified waste and contaminant commonly produced in the petroleum industry. In the recent past, there has been increased business growth in the oil sector, resulting in increased volumes of oily sludge characterized by high viscosity and toxicity. Therefore, sludge treatment before discarding is extremely necessary. This review seeks to highlight various
Ultrasound treatment technology has the advantages of high effi ciency, fast speed and no. secondary pollution. It is a "green" method w hich can treat oily sludge in a relatively short time
Recovery of fuel from real waste oily sludge via a new eco
The traditional extraction process for the sludge oil used only solvent to recover the fuel in traditional extraction unit. In this study, the new composite of the solvent and new surfactant
In addition to using the crude oil in oily sludge as the oil phase, Pickering emulsions can also be prepared using an external oil phase. A chitosan-based emulsion was prepared using petroleum ether as the oil phase. The emulsion efficiently removed heavy oil from solids, with a removal efficiency of 94.7–98.0% . In addition to the
Characterization and treatment of oily sludge: A systematic
To enhance the extraction efficiency, Sinopec Luoyang Branch utilized low-pressure steam as a heat source and employed oil retained at 180–300 °C as an extractant to recover 110–140 kg/t petroleum hydrocarbons (PHCs) from oily sludge containing 15% oil content (Mater et al., 2006). Despite the widespread use of solvent extraction in
Oily sludge, an inherent byproduct of the petroleum industry, presents dual characteristics of petroleum resources and hazardous waste. Owing to the unique physicochemical properties of sub-/supercritical water, hydrothermal technologies have been increasingly used for oily sludge treatment. This review is the first to focus on oily sludge
Status and prospect of oil recovery from oily sludge:A review
For this reason, Khan et al. (2019) developed a new method of using supercritical water to treat oily sludge and recover crude oil. At a temperature of 400 °C, a pressure of 30 MPa, and a 16.7 wt% content of emulsion, the recovery rate of oil products was found to reach 78.6 wt% after reacting for 60 min.
2.2. Effect of Dosage of Ionic Liquid on Oily Sludge Extraction Efficiency The oil recovery rate assisted with various ionic liquids solvent extraction is shown in Figure2. With the ionic liquid mass concentration increase in the extraction solvent, the oil recovery rate increased. For deep eutectic solvent ChCl/U, ChCl/EG and ChCl/MA, the oil
