Ecological feature of Urga field regional location is its dislocation in deserted region
characterized absence of industrial projects owing to the environment does not feel
considerable man’s impact.
One of the large objects affected formation of atmospheric background level in the
considered territory is preliminary gas treatment plant (GSP) of Urga field in which structure
there is the torch farm consisting of low and high pressure torches, intended for popping of
weathering gases formed at technological process of gas and condensate treatment.
Tank farm is the second by importance from the objects located in the given area,
consisting of six tanks for gas condensate reception, measurement, storage and shipment.
Sources of hydrocarbons emissions in atmosphere are six tanks; two pumps and gas
condensate loading station in tank lorries.
The ponds-evaporators located in close proximity to GSP are possible to characterize
as object with rather insignificant hydrocarbons emissions in atmosphere.
The boiler house of camp which working on natural gas concerns to additional
pollution sources of atmosphere. There is emitted the insignificant amount of harmful
substances in atmospheric air such as: nitrous dioxide and carbon oxide.
Quality of atmospheric air is defined both amount and conditions of emissions, and
scattering power of atmosphere.
There have been carried out the early calculation of stray fields under operation of
field for definition of existing situation of atmospheric air pollution, from which it is visible
that emissions of the harmful substances of Urga GSP in atmosphere do not create a
dangerous air gas content not by one of components of pollutants.
The concentrations created by emissions of harmful substances in atmosphere on
components are following:
- carbon oxide - peak concentration in atmosphere have no exceeding of
established norms in one of design point of the given area which values are
less than 0.01 MPC;
- hydrocarbons – peak concentration in atmosphere have no exceeding of
established norms in one of design points of the given area which values
does not exceed maximum-permissible norms of MPC;
- nitrous dioxide – peak concentration in atmosphere have no exceeding of
established norms in one of design points of the given area which value is
0.12-0.04 of MPC;
- nitrous oxide – peak concentration in atmosphere have no exceeding of
established norms in one of design points of the given area which value
does not exceed maximum-permissible norms of MPC.
Thus, due to distance of Surgil GCF from sources on Urga field there not be felt te
man’s impact.
