ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT FOR THE GAZA CENTRAL DESALINATION PLANT AIR DISPERSION & CO2 EMISSION STUDY

ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT FOR THE GAZA CENTRAL DESALINATION PLANT

This simulation study evaluates the atmospheric environmental impacts and compliance with national and international air quality standards for a small desalination plant (GCDP) located close to the seashore of Deir El Balah governorate, near Al-Qarara town. The single 6.5 m high stack is positioned at 31.40267 N, 34.31731 (UTM: 625,500, 3,474,800), 11 masl).

The plant operates with electricity from a combination of three Wärtsilä (16 V34 DF) reciprocating internal combustion engines (7.6 MW each) , burning diesel fuel (gasoil) or natural gas and an optional supporting photovoltaic unit, designed to replace one of the three diesel engines.  The total energy need/consumption is quoted at a slightly higher 24-25 MW. Using worst case assumptions, (emissions, meteorology) the dispersion modelling indicates that the dual fuel engines will not produce relevant emissions (in terms of ambient air quality standard violations, only NOx is relevant: estimated emissions amount to about 33 g/s). With the exception of NOx, summarized below, all expected maxima are orders of magnitude below the regulatory limit values, or, for the case of NO2, do not exceed the maximum number of permissible exceedances per year (as defined in 2008/50/EC).
