Torch designed characteristics are make: height is 35m, diameter is 0.4m. Torch is<br />
organized source if emissions. Temperature of mix discharge is 700 о С. Torch action period<br />
is the-all-year-round, 8760h/year.<br />
It will be constantly ingress in a torch the gas for maintenance of fire on duty only, in<br />
volume 10m3/hours, and also periodically gas from tank of condensate gathering of the<br />
mobile gaging separation installation in volume 3.78m 3 /hour. Total gas flow will make<br />
either 0.004m3/sec or 3.1g/sec.<br />
Emissions of harmful substances in atmosphere will make:<br />
М СО = 3,1 * 0.057 = 0.1767g/s = 5.5724t/year<br />
М NO2 = 3,1 * 0.002 * 0.8 = 0.005g/s = 0.1577t/year<br />
М NO = 3,1 * 0.002 * 0.2 = 0.0012g/s = 0.0378t/year<br />
М СН = 3,1 * 0.03 = 0.093g/s = 2.9328t/year<br />
Fraction content С 5+higher in burning gas is 0.99%t., hence, carbon black emissions are<br />
equal:<br />
М carbon black = 0.003 * 0.004 * 0.99 * 3457 * 10 -2 = 0.000411g/s = 0.01295t/year<br />
Speed of air-gas mix discharge is 0.2km/s<br />
Total emissions from a torch of one GSS will make 8.71365t/year, and from three<br />
26.14095t/year.<br />
Characteristics of the main designed sources of emissions of pollutants of <strong>Surgil</strong> field<br />
are listed in table 18.<br />
