Recovery of fuel from real waste oily sludge via a new eco
This study focused on developing a new cocktail extraction agent (CEA) composed of solvent and a new surfactant material (SM) for enhancing the efficiency of fuel recovery from real waste oil
The solvent extraction method utilizes the principle of “similar phase dissolution” to blend extractant and oily sludge in a specific ratio, facilitating the dissolution and separation of petroleum hydrocarbons (PHCs) from other components within the oily sludge. This process extracts the oil phase into the extractant, forming an extraction
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.
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.
A review of the application of different treatment processes
The results showed that the ultrasonic power was 75 W, the ratio of sludge to water was 1:4, the initial slurry under the condition of the material temperature of 25 °C had a reaction time of 6 min, and the oil recovery rate exceeded 60%. Hu et al. used ultrasonic extraction to recover crude oil from oily sludge from an oil refinery. Studies
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
Recent development in the treatment of oily sludge from
The upstream operation includes the processes of extracting, transporting, and storing crude oil, while the downstream operation refers to crude oil refining processes. The oily waste generated in petroleum industry can be categorized as either simple oil or sludge depending on the ratio of water and solids within the oily matrix [10]. Simple
Pyrolysis technology refers to the method of heating oily sludge under. the condition of micro-positive pressure without oxygen, in or d er to separate out oil and organic. matter, and segregate
Bioremediation of heavy oily sludge: a microcosms study
Oily sludge is a residue from the petroleum industry composed of a mixture of sand, water, metals, and high content of hydrocarbons (HCs). The heavy oily sludge used in this study originated from Colombian crude oil with high density and low American Petroleum Institute (API) gravity. The residual waste from heavy oil processing was subject to thermal and centrifugal extraction, resulting
Abstract. Oily sludge is one of the most important solid pollutants produced by petroleum industry. Due to the serious pollution and the increasing production of oily sludge year by year, how to effectively treat oily sludge is the focus of worldwide attention. This paper mainly introduces the source, characteristics, environmental impact, as
- How does the new extraction unit design improve sludge oil treatment technology?
- The new extraction unit design prevented the natural rotation from sticking to the wall whenever the rotational speed of the impeller enhanced the mass transfer rate in the DBBE unit, thereby improving the performance of sludge oil treatment technology.
- What are the future technologies for oily sludge treatment?
- With the improvement of national environmental protection requirements, oily sludge quality reduction, recyclable and harmless treatment technology will become the most potential technologies in the future.

- Which industry produces oily sludge?
- Moreover, the petrochemical industry is the primary producer of oily sludge. The components of oily sludge are a large, complex emulsified mixture of water; heteroatoms (e.g., N, O, and S); heavy metals (e.g., Cr, Cd, Cu, and Ni); crude oil; solid particles; and surfactants [ 1 ].
- How much oily sludge is produced in a refinery?
- Focusing on the refinery, the oily sludge waste generated depends on the processing scheme, oil storage system, and crude properties, but it is assumed that 1 ton of oily sludge is produced for every 500 tons of crude processed in the refinery ( Hu et al., 2013 ).
- What is oil sludge extraction and reclamation?
- The extraction and reclamation of oil from oily sludge presents an opportunity to mitigate the reliance on pristine crude oil reserves. This process not only optimizes resource utilization but also significantly contributes to the overarching goals of economic, environmental, and societal sustainability.
- What is thermochemical treatment of oily sludge?
- The thermochemical treatment involves adding hot water and chemical agents, mainly surfactants, to the oily sludge to alter the interfacial properties between oil and liquid phase through chemical crimping, emulsification, dissolution, and solubilization, reducing the viscosity of oily sludge (Lu et al. 2021).
