Emission inventory of primary air pollutants in 2010 from industrial processes in Turkey

Abstract

The broad objective of this study was to develop CO<inf>2</inf>, PM, SO<inf>x</inf>, CO, NO<inf>x</inf>, VOC, NH<inf>3</inf> and N<inf>2</inf>O emission inventory of organic and inorganic chemicals, mineral products, metallurgical, petroleum refining, wood products, food industries of Turkey for 2010 for both co]ntrolled and uncontrolled conditions. In this study, industries were investigated in 7 main categories and 53 sub-sectors and a representative number of pollutants per sub-sector were considered. Each industry was evaluated in terms of emitted emissions only from industrial processes, and fuel combustion activities were excluded (except cement industry). The study employed an approach designed in four stages, identification of key categories, activity data & emission factor search, emission factor analyzing, calculation of emissions. Emission factor analyzing required aggregate and firm analysis of sectors and sub-sectors and deeper insights into underlying specific production methods used in the industry to decide on the most representative emission factor. Industry specific abatement technologies were considered by using open-source documents and industry specific reports. Regarding results of this study, mineral industry and iron & steel industry were determined as important contributors of industrial emissions in Turkey in 2010. Respectively, organic chemicals, petroleum refining, and pulp & paper industries had serious contributions to Turkey's air pollutant emission inventory from industrial processes. The results showed that calculated CO<inf>2</inf> emissions for year 2010 was 55,124,263t, also other emissions were 48,853t PM, 24,533t SO<inf>x</inf>, 79,943t NO<inf>x</inf>, 31,908t VOC, 454t NH<inf>3</inf> and 2264t N<inf>2</inf>O under controlled conditions. © 2014 Elsevier B.V. © 2020 Elsevier B.V., All rights reserved.
