摘要：Environmental impact of gas burning parameters during operation of the gas pumping units of compressor stationswas studied. Simulation of the NO2, NO and CO dispersion zone at the excess air coefficients of 1.0; 1.1; 1.3; 1.6 was made using the Eol-Plus, v. 5.23 software package. Adjusted dimensions of the sanitaryprotective zone were established for various values of the excess air coefficient and according to the local windrose. It was determined that the smallest distance of emission dispersionwas at the value of α=1.00 and the largest distance was at α=1.60. It has been established that withincreases in the coefficient α, the near-earth concentrations of nitrogen oxides grow and those of carbon monoxide fall. It was found that concentrations of nitrogen oxides are minimal during gas combustion in the GB chambers at α=1...1.1. Recommendations for raising the level of environmental safety of the gas transportation facilities and a method of purifying exhaust gases from CO in operation of compressor stations on main gas pipelines were proposed. The method consists in an additional supply of ionized air in exhaust gases.
