Abstract (English):
The paper presents the results of studying the chemical composition of some samples of oil sludge produced at oil refineries of Turkmenistan. The study of oil sludge composition of Turkmenbashi complex of oil refineries (TCOR) and Seydi oil refinery (SOR) showed the presence of mechanical impurities in them: in samples (TCOR), RVS-No.208 -3.44% and RVS-Nj.216 -4.41%. The content of organic components of oil sludge in these samples, respectively, is as follows: asphaltenes 38.08% and 12.31%; resins 15.06% and 31.18%; oils 43.41% and 52.09%. In the sample RVS-No.246 the content of mechanical impurities 56,48% and oil products 43,52% (including: asphaltenes 2,36%, resins 3,65%, oils 37,51%). The composition of oil sludge sampled in the SOR (from the biological treatment plant - BTP and from the mechanical treatment plant - MTP): in the samples, BTP 62.37-62.92%; and in the sample of MTP 2.03% of mechanical impurities. The content of chemical components of oil sludge in these samples, respectively, is as follows: asphaltenes 1,7 and 7,87%; resins 16,10 and 17,58%; oils 19,45 and 72,52%. The method of processing of oil sludge from TCOR and SOR with gas condensate was studied and for comparison straight-run gasoline and reformate, which are semi-finished products of the enterprises, were used as extractants. As a result of the research, it was concluded that gas condensate used at the plant as an additional raw material can be successfully used as a solvent in the processing of oil sludge. For more complete extraction of oil products from oil sludge, their multistage processing by solvent is necessary.
