“…The landfill contains oil residues recovered during the cleaning of tanks for the transportation of crude oil from the fields of the Mangyshlak Peninsula. A study of similar landfills carried out by the authors of (Vdovenko et. al., 2015) showed that oil residues contained in landfills is subject to layer-by-layer phase separation.…”

The possibility of reuse of heavy residues (oily sludge) of low-sulfur, highly paraffinic Mangyshlak oils as a basis for fuel with improved environmental characteristics for engines to marine, river and railway transport, gas turbine and boiler plants, steam boilers and industrial furnaces was shown. A variant of the joint application of the methods of nuclear magnetic resonance, laser confocal microscopy and rheology for study of micro- and mesoscopic structure and some physicochemical properties of crude oil products has been developed. It has been shown that preliminary heating to 90 ° C leads to disruption of the structure and hydrogen bonds between oil associates and complexes, increasing sample homogeneity due to precipitation of solid impurities, partial removal of water content, air bubbles and dissolved gases. The addition of medium distillate diesel fractions to preliminary heated oil residues will make it possible to obtain a higher quality version of the fuel with a reduced resinous and asphaltene substances, lower pour point, good energy content and low sulfur content. Thus, valuable energy-containing raw materials can be reused. It should also be noted that the reuse of accumulated oil waste will reduce the harmful effects of landfills, will preserve the natural landscape, and will cut the cost of extracting natural resources.

“…The production of dangerous waste product generated by the petroleum industries in significant amount of sludge leads to the environmental pollution [5]. The sludge has the capability to pass through the ground and contaminate the soil, water and air [2]. Based on the studies, some of the polycyclic aromatic hydrocarbons (PAHs) which present in PS are shown in Fig 1 and detailed description of the hydrocarbons are illustrated in Table 1 [6].…”

“…The composition of PS is different hinge on the inception and storage state. PS is generally classified as a complex and stable emulsion-suspension system, with polycyclic aromatic hydrocarbons (PAH) and heavy metals [2]. Aliphatic and aromatics are the two major fractions of the sludge as it accounts up to 75% of the total content.…”

Petroleum sludge (PS) is a well-known hazardous waste because of its complicated compound. Leaching of petroleum sludge becomes a major threat to the environment if the waste is dumped illegally in landfills without proper treatment. Since, the petroleum sludge has the tendency to infiltrate into ground, eventually contaminates the soil and ground water. Therefore, the petroleum sludge needs to be treated before disposal to eliminate the negative impact to the environment. In this study, composting of PS by adding sawdust, soil and poultry manure has been carried out to produce compost that is low in polycyclic aromatic hydrocarbons (PAHs), heavy metals and with higher nutrient content. Each of the compost combination was homogenously mixed and stored in plastic container with good aeration using various ratios of 1:1:1:0 (control), 1:1:1:5, 1:1:1:8 and 1:1:1:10 volume-volume basis respectively, for two weeks. The result for PAHs by using Gas Chromatography/ Mass Spectrophotometry (GC/MS) shows fourteen types of PAH detected in PS. The total reduction of PAH in composts mixed were found to be 0.97%, 2.44%, 3,43% and 2.53% in compost design mix of 1:1:1:0, 1:1:1:5, 1:1:1:8 and 1:1:1:10, respectively. Besides, the result for heavy metals such as Al, Fe, Cu, Zn, Pb and Cd by using Atomic Absorption Spectrometer (AAS) shows the concentration in Fe (450.65) > Al (338.07) > Zn (52.7) > Pb (40.73) > Cd (39.56) > Cu (19.56) ppm. The best heavy metals reduction occurs to be in ratio of 1:1:1:10 where the Al, Fe, Cu, Zn, Pb and Cd decreased by 3.05%, 2.67%, 3.37%, 0.11%, 9.16% and 6.45% respectively. The carbon and nitrogen content in each ratio were determined by Total Organic Carbon (TOC) analysis and Total Kjedahl Nitrogen (TKN) analysis during the composting period. The Carbon to Nitrogen (C:N) ratio was maintained between 25 to 30 throughout the composting period. The composting process created a favorable condition for the microbial degradation of PS. Hence, based on the results obtained, best performing ratio to treat PS has been confirmed with ratio of 1:1:1:8. As a conclusion, co-composting can be a promising treatment method for disposal of PS.
