Capture of carbon dioxide from IGCC power plant through clathrate hydrate crystallization© Aristotle University of Thessaloniki (6/2009)
One of the new approaches for capturing carbon dioxide from IGCC (integrated gasification combined cycle) power plants is based on gas hydrate crystallization. The basis for the separation or capture of CO2 is the fact that the carbon dioxide content of gas hydrate crystals is different than that of the feed gas.
Industrial Air Pollution and the Permitting Procedure of three thermal Power Stations of the Public Power Corporation (P.P.C.) S.A. in Greece© Aristotle University of Thessaloniki (6/2009)
The three thermal Power Stations of the Public Power Corporation (P.P.C.) S.A. located in the Prefecture of Kozani caused significant air pollution problem due to their operation. This paper presents the Greek Ombudsman’s (GO), investigation for the legality of the Plants operation framework up to the end of 2005. Three main problems were revealed during the investigation. i. Air pollutant (and especially PM-10) emissions were above the admissible level on a systematic basis. ii. The power stations approved environmental terms had expired since 2002 and no renewal had taken place. Thus the industries operation was illegal. The issue was that the new environmental terms approval was delayed, because P.P.C. could not implement the Best Available Techniques that should have been incorporated in the terms decisions, according to the IPPC (96/61/EC) Directive requirements. iii. The three industries operation license was very close to expire and no progress was made on its renewal.
Statistical analysis of PM10 data in urban region of Volos, Greece© Aristotle University of Thessaloniki (6/2009)
Hourly measurements of particulate matter with an aerodynamic diameter less than 10 ÎĽm (PM10) recorded in the urban area of Volos, a medium-sized Greek coastal city, for a seven-year period, 2001-2007, are analysed. The main objective of this work is to study the typical behaviour of this air pollutant concerning diurnal and seasonal variations and meteorology dependencies.
