Prospects for natural gas fuel use
The paper considers the causes of big cities environmental problems, analyzes emissions chemical composition by priority sources of pollution; the influence of transportation-technological activities on air pollution is indicated. The composition of automobile exhaust gases is considered. The comparative dynamics of changes in the number of cars in Russia and other countries is given. Several fuel quality parameters are indicated. The amount of emissions from one average car is presented. The methods of minimization of vehicles impact on the ecology of megacities by abandoning the non-alternative monopoly on diesel fuel and gasoline are proposed. The necessity of modern technologies of oil and gas processing, expansion of opportunities of the country’s fuel market and improvement of its quality and environmental friendliness is revealed. The prospects for using gas fuel are determined, its classification is given, marked advantages over gasoline fuels are nominated. The volume of compressed natural gas (CNG) sales through PJSC “Gazprom” gas filling network is analyzed and the potential of CNG consumption in Russia for 2020 is calculated. The reduction of pollutant emissions is calculated according to the scenario of 50% of the vehicle fleet transfer to CNG. Economic and ecological effect of this market expansion is proved.
