The article is devoted to the issue of improving devices for cleaning gas station emissions from hydrocarbon vapors to improve the environmental safety of zones and territories of residential development. The largest part of the release of gasoline vapors entering the local aspiration systems is associated with the filling and emptying of fuel storage tanks at gas stations. It is known that emissions of benzene vapors belonging to the second hazard class have a significant problem in terms of exceeding the maximum permissible concentrations at the boundaries of the sanitary protection zones of gas stations and nearby residential buildings. Creation of new highly efficient technologies and devices for reducing the volume of pollutant emissions from gas filling complexes, while reducing operating costs by the amount of emissions and waste generated, developing reliable gas trapping devices of acceptable low material and energy consumption for gas station aspiration schemes is an urgent task. Another reason of elaborations’ needs of those gas trapping devices are reducing operating costs and environmental payments for emissions and waste. It was carried out environmental – economic research to verify justification to use absorption-type apparatuses within an absorbent mixture of sodium-magnesium salt’s solution (bischofite solution) and waste water of from a local purification device. It was allowed reducing emissions from sources of gas station aspiration schemes using capturing gasoline hydrocarbon vapors by mention above apparatus. It is essential reducing negative emissions’ impact of harmful substances and an additional amount of generated waste of gas stations. There are presented the results of calculating volume of the fees’ environmental damage, and economic efficiency of the use the proposed type of sorbent’ apparatus in this article also. The use of the proposed device in gas station aspiration schemes allows deceasing environmental payments for emissions including carbon taxes and fees and additional operating costs in terms of the use of consumables. The successful tests carried out have shown the reliable and efficient operation of the pilot plant with the proposed device at the gas station. The successful tests carried out have shown the reliable and efficient operation of the pilot plant set up with the proposed device that decreased environmental payments for emissions, waste and operating costs.
