The present study is performed with the aim to reduce the levels of polluting emissions from fuel combustion that produce acid rains and the greenhouse effect (NOx, CO2). The electric field effects on the processes of heat/mass transfer and propane combustion are studied in order to perform electric...

The aim of this paper is to identify the factors that have influenced changes in the amount of carbon dioxide (CO2) emitted from the Greek manufacturing sector as a whole and from three representative subsectors. By means of an algebraic decomposition method the changes recorded during the period...

Electricity generation is the single most important sector in which CO2 reductions are achievable, with advanced generation technologies available and the existence of a centralised production structure, if compared to the transport or the industrial sector. It is a market undergoing a radical...

The photocatalytic degradation of protocatechuic acid, a biorecalcitrant polyphenolic compound typically found in olive processing and wine distillery waste waters, has been investigated in aqueous heterogeneous solutions containing semiconductor powders (TiO2, ZnO) as photocatalysts, both in the...

Analysis and simulation of the behaviour of gas turbines for power generation using different nonconventional fuels obtained from different renewable sources are presented. Three biomass-tobiofuel processes are considered: anaerobic digestion of biomass (biogas), biomass gasification (synthesis gas)...

In this paper, a detailed spatial allocated emissions inventory for Cyprus is presented. Topdown and bottom-up methodologies are implemented and emissions are estimated from all anthropogenic sources for the reference year 2002 with the aid of state-of-the-art algorithms. Emission factors...

Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO2, NO, and NO2 from “sweet” natural gas while “sour” gas emits SO2 in addition; incomplete combustion...

The process of nitrification in wastewater treatment is widely accepted as a two-step process. In the first step the ammonia is oxidized to nitrite, a process considered to be carried out mainly by the Nitrosomonas sp., while in the second step the Nitrobacter sp. oxidizes the nitrite to nitrate...
