Emissions of harmful substances in atmosphere are calculated according to method
[4] and will make:
Мсо = 279.298 х 0.057 = 15.91999g/sec = 502.0527t/year
М NO2 = 279.298 х 0.002 х 0.8 = 0.446877g/sec = 14,09271t/year
М NO = 279.298 х 0.002 х 0.2 = 0.111719 g/sec = 3,523177 t/year
М СН = 279.298 х 0.03 = 8.37894 g/sec = 264,2383 t/year
There is absent hydrogen sulfide content in gas.
Fraction content С 5+higher is equal to 0.99%. Volumetric gas discharge is equal to
0.141m 3 /sec.
М carbon black = 0.003 х 0.141 х 0.99 х 3457 х 10 -2 = 0.01448g/s = 0.0.45664t/year,
Total emission from LPF will make 784.363527t/year.
High pressure torch
Source of emissions will be HPF by height – 35m, diameter – 0.7m. Temperature of
mix discharge is 700 о С. Torch action period is all-the-year-round, 8760h/year.
There will ingress gases in a torch:
- from separator 429m 3 /hour by density 0.8042kg/m 3 ;
- aeration 250.5m 3 /hour by density 0.898kg/m 3 ;
- aeration 429m 3 /hour by density 1.21kg/m 3 ;
- from separator 264m 3 /hour by density 0.85165kg/m 3 ;
- aeration 1.41m 3 /hour by density 1.06383kg/m 3 ;
- gas for maintenance of fire on duty 12m 3 /hour with average density 0.8kg/m 3 .
Gases weight flow on a torch will make:
В = (429 х 0.8042 + 250.5 х 0.898 + 429 х 1.21 + 264 х 0.85165 + 1.41 х 1.06383 + 12 х
0.8) х 1000 / 3600 = 368.049g/sec.
Emissions of harmful substances in atmosphere are calculated according to method
[4] and will make:
Мсо = 368.049 х 0.057 = 20.97879g/sec = 661.5872t/year
М NO2 = 368.049 х 0.002 х 0.8 = 0.588878g/sec = 18.57087t/year
М NO = 368.049 х 0.002 х 0.2 = 0.14722g/sec =4,642717 t/year
М СН = 368.049 х 0.03 = 11.04147g/sec = 348.2038t/year
There is absent hydrogen sulfide content in gas.
Fraction content С 5+higher is equal to 0.99%. Volumetric gas discharge is equal to
0.385m 3 /sec.
М carbon black = 0.003 х 0.385 х 0.99 х 3457 х 10 -2 = 0.039529 г/с = 1.24659 t/year,
Total emission from HPF will make 1034,25 t/year.
Condensate pump house
Source of emissions will be the pump for condensate swapping. Conditional
characteristic of the source: height - 2m, diameter - 0.5m. Sources action period is all-theyear-round,
8000h/year.
Specific emissions of hydrocarbons during condensate swapping make 0.039g/s,
according to table 3.5 [4], hence, total emissions of hydrocarbons during condensate
swapping will make:
М сн = 0.039 х 3600 х 8000 х 10 -6 = 1.123 t/year
