The peculiarities of the Tuapse refinery installation of primary oil refining ELOU-AVT-12 commissioned in 2013 were shown. The device is intended for dehydration and desalting of oil. Analyzed: tube furnace N-1001/1,2 for heating oil and oven N- 2001/1,2,3,4, for heating the distilled fuel oil. Tube furnace ELOU is one of the main sources of air pollution. We have performed quantitative chemical analysis of gas emissions furnace ELOU AVT and determined percentage of components O2, N2, CO in the emissions. The content of carbon monoxide in emissions was less than 0.05%, which corresponds to the standards. The average nitrogen content is 80%, which also corresponds to standard indicators

Physical and chemical characteristics of the Stavropol oil are provided. The found value of density of 853,6 kg/m3 is low and shows that oil mainly contains light paraffin hydrocarbons. Distillation of test of oil is carried out on the device of rectification of ARN-2 oil to laboratories of the Tuapse oil refinery. On the basis of experimental data, the curve of oil ITK is constructed. The chromotographic analysis determined a mass fraction of C1-C6 hydrocarbons in a model of test of oil. The conclusion is drawn that according to GOST 31378-2009 regulations the sample of oil can be carried depending on a mass fraction of sulfur to the 2nd class ("sulphurous"); on density – to the 2nd type ("averages"); on content of chloride salts, waters, mechanical impurity – to the 1st group; on a mass fraction of hydrogen sulfide, marked - and etilmerkaptan in the amount – to the 1st type. The sample of oil is characterized by the low temperature of hardening (minus 15 °C)

Production ecological control is an integral part of the national environmental monitoring system. The article describes the results of production ecological control of impurity of groundwater drawn from wells in the territory of the Tuapse refinery and presents a situational plan of wells layout in the Tuapse refinery. Analysis of groundwater was represented from 2012 to 2016 with their content (mg/l) of oil, phenols, plumbum, chloride, and anionic surfactants. We have revealed the excess of oil products and phenols and developed measures to reduce concentrations of these substances in the groundwater refinery in Tuapse

When combustion of fuel in thermal power plants, combustion products are formed, which contain: fly ash, particles of unburnt pulverized fuel, sulfuric and sulfur dioxide, nitrogen oxide, gaseous products of incomplete combustion, sodium salts, soot particles, calcium dioxide, etc. Getting into the atmosphere, they cause great harm to the components of the biosphere. The article presents a laboratory analysis of industrial emissions into the atmosphere of 1-7 power units for 2015 and 2016 at Novocherkassk State District Power Plant. The components NO2, NO, CO, SO2, C (soot) have been determined. It is established that for the whole observed period of excess of maximum permissible emissions was not revealed. Emissions of each of the components are within the same level and are stable

The article considers scheme of sewage treatment plants AG-STOK of Novorossiysk trading sea port, designed to clean the surface runoff from the territory of industrial sites and residential areas to the norms of discharge in the drainage network. The installation includes a well-separator, a storage tank, mechanical cleaning of solids on a mechanical filter, filtration through a filter with granular loading and filtration through a filter with sorption loading. The treated runoff, which corresponds to the conditions of discharge into the urban drainage network, accumulates in a tank of clean water and is diverted to the storm sewer network. There are: the scheme of treatment facilities, the explication of equipment, a photo of a mechanical filter, a filter with a granular load and a filter with a sorption load. The indicators of surface runoff correspond to the norms of the maximum permissible discharge

The article describes the sources of noise Yeisk thermal power plant (TPP) in excess of the permissible sound pressure levels in homes on the street. Gorky, 25. Eisk TPP is located near the residential area, where the permissible noise level standards adopted much more stringent than in the power plants. Prolonged exposure to noise leads to human disease noise disease. The scheme of movement of exhaust gases from the thermal power plant generating units Yeisk. Analysis of measurements of noise characteristics of main and auxiliary equipment showed that one of the main sources are sectioned estuaries double-barrel pipe height of 27 m and slices estuaries pipes emergency explosive valves flues installed on the roof at a height of 17 m. The previous Noise reduction nozzles that emit noise uniformly in all directions are replaced by advanced, whose index changed direction estuaries sections double-barrel tubes. This will change the level of radiated noise in residential development. If you change the angle of orientation of 135°-180°, the noise level in residential construction decreased by 7-10 dB. Shows a photograph of thermal power plants, residential buildings, the old and improved silencers

After silage of ash captured by the electrostatic precipitator, we installed the cyclone of NIIOGAZ CN-15-500 for exhaust gas pre-treatment of the ash resulting from the process of burning solid fuels (coal of Donetsk) in boilers of Novocherkassk hydro power plant. The plant cyclone examination was performed in a production environment of Novocherkassk hydro power station comprising 4 cylindrical cyclone element diameters of 500 mm, and is defined by its real effectiveness, which amounted to 91%. After the cyclone, the gas enters the two-bag filter FRKI-90KP3-2-2 designed to trap solid ash residues and installed over the silo dry ash. Filters are manufactured in climatic design for temperate and cold climate with the accommodation category 4. The article shows the characteristic of the test results and bag filters FRKI- 90K-P3-2-2 before and after the cyclone in the cleaning system.
