Krasnodar GRES Project Volume I11 Environmental Assessment

3.3.4 Estimated Plant Emissions
Air, water and thermal effluents estimated to be emitted from the Krasnodar GRES
meet or exceed all requirements of the Russian Federation, World Bank and
appropriate international requirements. Effluent values were calculated based on
the plant's design and fuel analysis above, and are described below. A detailed
discussion of their environmental implications is found in Chapter 5.
3.3.4.1 Air Effluents
Air emission calculations were based on simultaneous operation of two
combustion turbines, one steam turbine and two HSRGs producing 900 MW.
Emissions data under these conditions, given a flue gas flow of 23.4 mls, a stack
gas temperature of 120" C., a stack internal diameter of 14.4 meters, and the
natural gas constituents listed above, are tabulated below. It should be noted that
the calculated emission rates are within the regulations and guidelines of the
Russian Federation and World Bank.

Process water releases to the Laba River are estimated at 116 cu.m./hour.
Contaminant concentrations and the thermal quality in these waste waters will
meet or better the values listed in the table below, and these values are within
Russian Federation and World Bank regulations and guidelines.
