REDUCTION OF NOISE OF ENVIRONMENTAL POLLUTION BY INSTALLING SILENCERS
DescriptionThe 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

Description
The power plant being investigated is Novocherkassk State District Power Plant located in the settlement of Donskoy, Rostov region. The power object is included in the list of objects of the fuel and energy complex subject to categorization and is defined as critically important. The analyzed site is the "subsidiary farm", which includes a chemical reagent warehouse and a site for chemical water purification, where hazardous substances are treated: sulfuric acid and technical sodium hydroxide. The analysis of the main causes of accidents at thermal power stations occurred during processing, storage and transportation of hazardous substances, and typical scenarios of possible accidents at the chemical water treatment plant of thermal power plants were considered

A SURFACE RUNOFF CLEANING PLANT FOR THE TERRITORY OF THE NOVOROSSIYSK SEA PORT
DescriptionThe 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

PHYSICAL AND CHEMICAL PROPERTIES AND FRACTIONAL COMPOSITION OF THE STAVROPOL OIL
DescriptionPhysical 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)

CHRONOLOGICAL STUDY OF CONFIGURATION OF A WATER – BOILED PROTEIN SYSTEM WHEN DRYING
DescriptionThe article presents results of research on drying a slurry consisting of distilled water and finely chopped cooked chicken protein of table eggs. The suspension is placed in a Memmert oven, which has temperature of 60 °C. In the process of removing moisture when drying the slurry of water - boiled protein we examined kinetics of its drying and performed chronological photographing of conformation of the system of water - boiled protein. The final weight of the protein remaining after evaporation, was 0.06 g corresponding to 26% by weight of cooked protein source in an amount of 0.23 g. The analysis of the system appearance including the evaporation of the water showed that the protein was originally white, and this color does not undergo any changes until 35 minutes of drying, i.e. when the main base is water. Upon further drying of the suspension, starting with 40 minutes, boiled protein literally "melts" in the surrounding water residues; and as it is disappearing, becoming more and more transparent. Meanwhile, the forms of the protein are becoming round and transforming into the form of liquid crystals. The final phase of the protein is a solid transparent film

Description
We have performed an experimental study of the evaporation process at a temperature of 105 ° C for the egg white model solution in distilled water to evaluate the ratio of the heat transfer coefficient from air to water ratio mass transfer to the water surface into the air by evaporation from the free surface in a forced convection. Evaporation of the solution was carried out in a Memmert oven of class Basic (Germany) equipped with forced air circulation, the control panel with a display and a temperature control device. To determine the surface temperature at which the main evaporation of water from the process solution, the experiment conducted under the same conditions by measuring the average temperature of the layer of water sample, placed in a Petri dish in an oven with a sensor - DMM Mastech M838 series. It is found that the coefficient of heat transfer from air to water almost a thousand times greater than the coefficient mass transfer from the water surface into the air
