7 FORECAST OF ENVIRONMENTAL CHANGES AND
ECOLOGICAL CONSEQUENCES AS A RESULT OF
OBJECT REALIZATION
As a result of designed objects functioning there will be additional impact on
atmospheric air from emissions of pollutants, such as carbon oxide, nitrogen oxide and
dioxide, various hydrocarbons, i.e. environment will be subject to chemical impact.
Physical impact can be expressed in soil load during construction and installation of
industrial areas equipment, during laying of pipelines, TL, communication lines, highways,
and also in bringing of noise, vibration, electromagnetic radiations.
As it has been shown in subsection 4.5, bringing of the chemical substances during
operation of objects will be defined, basically, by emissions in atmospheric air of saturated
hydrocarbons, and also fuel gas combustion products and will make about 1941.936t/year.
For the purpose of definition of pollution level of atmospheric air by predicted
emissions there has been carried out dispersion calculation on the area 5х5km with use of
the bundled software "Ecologist". Concentrations calculation was spent only from emissions
of designed objects. Analysis of calculations has shown, that:
Nitrogen dioxide - largest prospective level of atmospheric pollution is supposed on
the given component (figure 13). Peak concentration will make 0.51 MPC (directly close to
CGTU), at the distance of 700m from area the concentrations are decrease up to level 0.23
MPC, at the distance of 2000m from area the concentrations do not exceed level 0.1 MPC.
Nitrogen oxide – bringing level of the given component is predicted by small
amounts (figure 14) – peak concentration will make 0.01 MPC (directly close to Surgil
CGTU)
Carbon oxide – bringing level of the given component is predicted by small amounts
(figure 15) – peak concentration will make 0.04 MPC (directly close to Surgil CGTU), least
- 0.01 MPC (at the distance of 2500m from CGTU).
Hydrocarbons (of methane) – bringing level of the given component is predicted by
small amounts (figure 16) – peak concentration will make 0.06 (directly close to Surgil
CGTU), least - 0.01 MPC (at the distance of 1000m from CGTU).
