Winter Southern wind flow and air pollution episodes over Athens, Greece


Kassomenos P.A., Lykoudis S. and Kallos G.


The greater area comprising the Attica peninsula and the Saronic Gulf is greatly influenced by various local circulation types. During winter months, moderately high air pollutants concentrations are observed when the prevailing condition is either stagnant or a weak southern flow. The case studied...

Relation between air pollution episodes and discomfort index in the greater Athens area, Greece


Paliatsos Ath. and Nastos P.


An attempt is made for a first general study of the relation between high/very high concentrations of nitrogen dioxide and ozone with the discomfort index (DI) values. The nitrogen dioxide data of «Patision» station and ozone data of «Liosia» and «Marousi» station have been analysed. The relation...

Modeling of Anaerobic Digestion - A Review


Lyberatos G. and Skiadas I.V.


Anaerobic digesters often exhibit significant stability problems, that may be avoided only through appropriate control strategies. Such strategies require, in general, the development of appropriate mathematical models, which adequately portray the key processes that take place. This paper reviews...

Hydrodynamic and water quality modelling of Southern Evoikos Gulf, Greece


Stamou A.I., Noutsopoulos C., Pipilis K.G., Gavalaki E. and Andreadakis A.


A mathematical model is presented, consisting of a two-layer, finite difference hydrodynamic submodel and a compartmental water quality sub-model. The model is calibrated with field data. Then, it is applied to Southern Evoikos Gulf, an open coastal water body of particular ecological significance...

Promotion by Sodium in emission control catalysis: The difference between alkanes and alkenes in the Pd-catalysed reduction of NO by hydrocarbons


Yentekakis I.V., Konsolaki M., Kiousis V., Lambert R.M. and Tikhov M.S.


The activity and selectivity of Pd catalysts supported on YSZ and dosed with different amounts of Na promoter has been investigated for the reduction of NO by alkenes (C3H6) or alkanes (CH4). It is found that Na strongly promotes the reduction of NO by C3H6. Rate increases by an order of magnitude...

Organic atmospheric pollutants: polycyclic hydrocarbons from coal atmospheric fluidised bed combustion (AFBC)


Mastral M., Callen M.S., Murillo R. and Garcia T.


The work deals with coal combustion in a pilot-plant fluidised bed (7 cm i.d.) under atmospheric conditions. The aims are to capture and analyse qualitatively as well as quantitatively the volatile polycyclic hydrocarbons emitted by using coal as energy source under various combustion conditions...
