To research results of level's polution of the air at the area of location of gas feeling station to decrease exhaust of hydrocarbons' vapors
Incoming article date: 29.02.2020The article is devoted to the issue of improving the environmental safety of highly urbanized territories. The article presents the results of field measurements of pollutants into the atmosphere from gas stations within the urbanized territories of cities of the Russian Federation. The largest part of the allocation of oil product vapors entering the local aspiration systems is associated with the operations of filling and emptying fuel storage tanks at gas stations. The results of field measurements of the values of hydrocarbon concentrations obtained on the basis of the values of maximum permissible concentrations of ingredients are presented. The conclusion is drawn on the feasibility of environmental protection measures to reduce emissions when finding housing in the border area of the sanitary protection zone (SPZ) of gas stations. To reduce emissions from gas station sources, it was proposed to equip the gas aspiration system of the gas feeling tank with an improved design of the absorption device. In order to reduce waste generation as a working agent in such devices, it was proposed to use wastewater with a certain amount of oil products from a local gas station treatment device. This approach also allows to reduce the negative anthropogenic impact of gas stations in terms of the formation of additional amounts of waste generated during their operation. Successful tests have shown reliable and efficient operation of the pilot plant with the proposed apparatus.
