G01V 9/00
PCT/RU2012/000811ZHURAVLEVA, Elena DavydovnaZHURAVLEVA, Elena Davydovna
The hydrogeochemical method for determining accumulations of hydrocarbons comprises the following stages: taking samples of underground water, processing the samples taken with an organic solvent in order to produce an extract of organic compounds in said solvent, separating the extract produced from the aqueous medium, freezing the extract produced, for example with liquid nitrogen or liquid hydrogen, carrying out fine-structural spectral analysis of said frozen extract, with a quasi-linear spectrum of luminescence of benzene being recorded, and measuring the intensity of the analytical line of benzene in the spectrum, on the basis of which an opinion is formed regarding the presence of accumulations of hydrocarbons. According to the invention, samples of underground water are taken; samples of surface water are additionally taken; standard hexane is used as the solvent for each sample; the intensity of the analytical lines of benzene in the spectra of the samples of underground and surface water is compared; and, in the event that the intensity of the analytical lines of benzene in the spectra of the samples of underground water is exceeded, an opinion is formed regarding the presence of accumulations of shale gas. Such a method makes it possible to increase the reliability of identifying accumulations specifically of shale gas, to simplify prospecting technology and also to reduce economic and ecological risks.

PCT/RU2012/000815ZAKRYTOE AKTSIONERNOE OBSCHESTVO "TORGOVIY DOM "ORGKHIM"TSEBULAEV, Victor Alekseevich
The present invention relates to the chemical or petroleum-processing industry and can be used in the production of petroleum plasticizers for synthetic rubber and tyres. In the method for producing non-carcinogenic aromatic process oil, containing a PCA extract of less than 3.0% according to the IP-346 method, said method comprising purifying the oil fractions of petroleum with selective solvents and separating the extract, additionally processing the extract with a polar solvent and producing a raffinate as the end product, the polar solvent used is a mixture of dimethylsulphoxide and N-methylpyrrolidone, which is used for preliminary processing of the extract, wherein, after the preliminary processing, the mixture of extract and polar solvent is filtered, divided and the light phase is sent to the additional processing of the extract with the polar solvent, and the heavy phase is sent to a polar solvent regeneration stage. The ratio of dimethylsulphoxide to N-methylpyrrolidone in the mixture is within the range of 1:0.1-0.5. The ratio of polar solvent to extract in the additional processing stage is within the range of 1.5-2.5:1. The ratio of polar solvent to extract in the preliminary processing stage is within the range of 0.1-0.3:1. The technical result consists in increasing the efficiency of the process by preventing the formation of an intermediate layer in the extractor column, by reducing the ratio of solvent:extract, and, as a consequence, by increasing the productivity of the plant, simplifying the process of drying the solvent, and eliminating a paraffin-naphthene solvent, which substantially simplifies the regeneration of extractant from the raffinate solution.
