“O’ZLITINEFTGAZ” PC
PFS “Surgil field complex costruction with valuable
components retrieval”
Source of emissions will be relief valves of tank for oil. Source height is 2m,
diameter - 0.1m. Source action period is 24 hours a day, 8760 hours per year. Temperature
of air-gas mix emission is 25 о С.
Annual receipt of oil in tank has made 292 tons. Oil density is 0.9t/m 3 .
Oil volume which has ingress in tank is equal:
V = 292 : 0.9t/m 3 = 3.24m 3
Amount of the hydrocarbons departing from a source is defined by method [5],
taking into account specific losses.
For oil the specific losses are equal 4 х 10 -6 t/m 3 , according to method 1 [5].
Emissions of hydrocarbons are equal:
М сн = 3,24 м 3 х 4t/m 3 х10 -6 = 0.000013t/y = 0.0000004g/s
Boiler house chimney
The source of heat supply of Surgil CGTU objects accepts a boiler-house. A source
of emissions will be chimney of boiler house by height of 15m, by diameter of 0.264m. Fuel
gas flow for boiler house will make 10.3m3/hour or 0.003m3/sec. Temperature of
combustion gases discharge makes 225°C. Action period is 3520h/year.
Gas combustion heat 45 MJ/kg. If the gas density is 0.81kg/m 3 , so gas weight flow
make 2.43g/sec. Emissions of harmful substances in atmosphere during gas popping are
calculated according to method [4] and will make:
М СО = 0.001 х 2.43 х 0.5 х 0.5 х 45 х 0.995 = 0.0272g/sec = 0.3447t/year
М NO2 = 0.001х 2.43 х 45 х 0.09 х 0.8 = 0.0079g/sec = 0.1001t/year
М NO = 0.001х 2.43 х 45 х 0.09 х 0.2 = 0.002g/sec = 0.0253t/year
Total emission from boiler house makes 0.4701t/year.
Internal combustion engine (ICE)
Source of emissions will be the diesel generator used for the electric power
generation. Source height is 3m, diameter is 0.2m. Temperature of exhaust gases discharge
is 120°C. Action period is 24hour/day, 8760hour/year.
Diesel fuel rate for ICE operation will make 0.293t/day or 106.945 tons in time of
action period 365 days.
Total and maximum-one-time emissions during ICE operation will make:
М NO2 = 106945kg х 30g/kg х 10 -6 = 3,20835t/year = 0.101736g/sec
М СО = 106945kg х 25g/kg х 10 -6 = 2.67363t/year = 0.08478g/sec
М SO2 = 106945kg х 10g/kg х 10 -6 =1.06945t/year = 0.033912g/sec
М СН = 106945kg х 12g/kg х 10 -6 = 1.28334t/year = 0.040694g/sec
М акр = 106945kg х 1.2g/kg х 10 -6 = 0.12833t/year = 0.004069g/sec
М carbon black = 106945kg х 5g/kg х 10 -6 = 0.53473t/year = 0.016956g/sec
Total emission from ICE will make 8.89782t/year.
