The methods of using geographic information systems in solving problems of monitoring of oil spills are investigated. We have proposed the model of geographic information system for monitoring, forecasting, and oil spill response

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 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

The object of the study was the sweet pomace of red varieties of grapes grown in village Taman Temryuk district of the Krasnodar region. By grinding in a laboratory mill and drying in a drying oven at a temperature of not above 60 ºC, a powder is obtained from the mash. Its quantitative chemical analysis has been carried out. The mobile forms of metals and the total content of metals are determined. The content of mercury, lead, arsenic does not exceed the permissible levels of the maximum content of toxic elements in flour confectionery products. The influence of powder from grape pomace on the quality of the finished product and on the properties of the pastry test was studied, as the control sample was chosen the recipe for the sugar cookies "Carrot". A part of the flour was replaced with grape-dried powder in amounts of 1 %, 2 %, 5 % of the mass of wheat flour of the highest grade in the test. The recipe of sugar cookies with the addition of powder from grape pomace and without, calculated on 200 g of finished product, and organoleptic parameters of the finished biscuit is given. It is established that the use of grape-dried powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in confectionery products, as well as to enrich them with mineral substances, microelements, which are necessary for normal functioning of the organism. Biscuits with the addition of powder from grape pomace are a good source of ballast substances reducing caloric content, which contributes to the removal of harmful substances from the body: cholesterol, heavy metal salts, etc
