Thus during UGCC operation atmosphere will receive products resulting from fuel gas
combusting in the process plants as well as hydrocarbons (methane).
It is clear that during UGCC operation 11 kinds of emissions will be discharged into the air in
amount of 2,482.164904 tons annually. The main part is carbon monoxides (35.879%) generated
during flare operation.
Since UGCC site is 4-5km away from Akchalak CS level of air pollution from the total emissions
of GCC and CS was assessed to decide concerning appropriateness of the dwelling settlement
construction in this area.
Akchalak CS consists of four compressor departments equipped with gas-blower park each. CS
had only three aggregates of GTK-10-4 type with capacity of 10MW and 17-23% real efficiency.
Averaged specific emissions values for these aggregates are: carbon monoxide – 150mg/m 3 ; nitrogen
oxide – 120mg/m 3 .
