1.3.1 ATMOSPHERIC AIR
The stated climatic features of considered area predetermine necessity of the account
of impact of the sources which are in considered area at definition of air modern condition
estimation.
Atmospheric air condition is in close dependence on climate indexes of considered
region.
The most typical feature of Surgil GCF is its location in sparsely populated deserted
area with a small amount of sources of the artificial pressure on environment owing to there
is rather low level of anthropogenic impact on the natural complexes.
The main nearby sources of atmospheric air pollution is East Berdakh field. During
extraction and treatment of hydrocarbon raw stocks on the given field the sources of
pollutants emissions are: emergency-torch farm, tank farm and pump house for condensate
transfer, DEG regeneration plant and a boiler house. From the given sources there are
ingress in atmosphere the hydrocarbons (by methane), and also products of firing on torches
and boilers.
The quantitative characteristic of emissions on the given sources of atmospheric air
pollution is presented in table 3.
Table 3 - Pollutant emissions near Surgil field construction region, t/year
Components
Emissions, t/year
(East Berdakh)
Methane 94,25
Carbon oxide 85.65
Nitrous dioxide 3,17
Nitrous oxide 0.79
Carbon black 0.8
Total 184,66
Peak pollutants concentration created by emissions of East Berdakh field have local
spreading and practically do not impact on atmosphere contamination level in the region of
Surgil field. Thus, atmospheric air condition in the designed region is satisfactory that is
important factor for further designing of the construction objects of Surgil GCF. It is
possible to say so about objects of Urga field and also about existing objects of Surgil GCF.
