Abstract
The main objective of this study is to investigate air pollution in Port Sudan
city due to nitrogen oxides (NOx) exhaust emissions from stationary diesel
generator units located in certain areas of Port Sudan city (areas east city,
Port Sudan harbor, eastern parts of city center and the National Electricity
corporation station-Station A).
This objective is achieved by measuring nitrogen oxides concentration in
exhaust emissions from diesel generator units and estimating nitrogen oxides
emission rates. Nitrogen oxides concentrations are measured using a single
gas exhaust gas analyzer (the Kane Auto 1-NOx gas analyzer) and
measurements are taken directly from the exhaust pipes of the diesel engines
driving the generator. Nitrogen oxides emission rates are calculated in
g/kWh using United States Environmental Protection Agency (U.S EPA)
test method no.19 which is used for determination of sulphur dioxide
removal efficiency and particulate matter, sulphur dioxide, and nitrogen
oxides emission rates.
Calculated nitrogen oxides emission rates are then compared with U.S EPA
emission standards for stationary compression ignition engines. Many diesel
generators are found exceeding standards and Chinese type single cylinder
type of generators together with diesel generators located in station (A) of
the National Electricity Corporation are found to have the highest NOx
emissions.
Future works on pollution problems encountered in Port Sudan are
recommended.
