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

The 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

Groundwater is the source of drinking water in rural areas, it is a part of urban water and it is formed due to the filtering of cross waters in a stratified medium permeable rocks. The impact of anthropogenic factors leads to changes in the qualitative composition of groundwater. The article presents the results of industrial environmental monitoring of ground water refinery of Tuapse in the period from 2012 to 2016 according to its content of ammonium-nitrogen, nitrate-ions, sulphates, formaldehyde, toluene, xylene and ethylbenzene. Analysis of groundwater sampled from wells located at the site of the refinery was conducted by a factory-certified laboratory. The content of the components meet the regulatory indicators. We examine the effects of industrial toxicants on the human body

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. The work presents the analysis of the composition of the ash and compares it with published data. It is experimentally proved that the inclusion of Cyclone CN-15-500 in the process diverting gas purification scheme allowed more efficient operation of fabric filters, reducing the dust significantly for the input gases

The content of metals in raw rice is determined. Inversion voltammetry (IVA) was carried out in an accredited laboratory on the "Ta-Lab" device of the company "Tom-Analit" LLC according to the approved method of ERD F 16.1: 2: 2.2: 2.3.46-06. Silicon dioxide is determined according to ERD F 16.1: 2: 2.2: 3.65-10 and humidity according to GOST 5180-2015. Preparation for the IVA is illustrated. Voltammograms of the potential difference of the chloride-silver reference electrode are compared with the current strength of the indicator mercury-film electrode of electrochemical cells. It has been established that the main metals of the raw rice called Regul grown in the Krasnodar region are: copper 1.6 ± 0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5 mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and silicon dioxide 6.5 mg/kg. The presence of iron is associated with the wear of gravity. The content of zinc, manganese and silicon dioxide corresponds to this type of grain. The presence of copper and lead is associated with the absorption of heavy metals from the soil

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

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 electric method of gas dedusting is the most effective, since it allows capturing solid particles with a size from 0.01 µm to tens of microns. The efficiency of dust and gas cleaning equipment of Novocherkassk SDPP for cleaning flue gases from ash at power units 1-7 in the period from February 2015 to February 2017 is considered. The main equipment is electrostatic precipitators. As a solid fuel, Donetsk culm is used. It is established that the efficiency of waste gas purification at power units 5-7 was about 99 %, while at power units from the 1st to the 4th this value was within 95-96 %. The data obtained correspond to the design data, but it is recommended that the cleaning devices be improved to improve their efficiency. The most acceptable is a combined electrofilter-bag filter

The flowsheet purification of exhaust gases in the Novocherkassk SDPP after the electrostatic precipitator on I-th stage of purification set group cyclone, on the II-nd stage of purification - baghouse. To determine the particle size distribution of fly ash, we selected ash from the transport network to the group cyclone, and the in a group cyclone, and in a baghouse. With the help of the microscope "Biomed- 3" we produced pictures of ash particles with different magnification. Granulometric composition of three selected ash samples were determined according to the mass content of particles of different grain size, expressed in percent relative to the weight of dry ash sample taken for analysis. For size fractions from 10 mm to 0.5 mm sieve method is applied without rinsing with water, for size fractions less than 0.5 mm sieve method is applied with water washing. The particle size of the ash mixture, taken up before the cyclone,
