This study assesses whether the deployment of CO
2
capture technologies in the European industrial
sector would result in significant changes in the emissions of air pollutants (NO
x
, SO
2
, PM, and NH
3
) in
the short term. The industrial sectors investigated were: cement, petroleum refineries, and iron and steel.
The analysis included onsite emissions and changes associated with grid electricity consumption due to
CO
2
capture. Post-combustion capture using monoethanolamine (MEA) was considered for the cement
sector and petroleum refineries, and Top Gas Recycling Blast Furnace (TGRBF) with vacuum-pressure
swing adsorption (VPSA) for the iron and steel sector.
The results show that when all three industrial sectors in the EU-27 are fully equipped with CO
2
capture,
industrial SO
2
emissions in the EU-27 may decrease by 40–70% whereas NH
3
emissions may increase by
120–520% (equivalent to 2–8% of total European emissions). The large increase in NH
3
emissions is due to
the degradation of MEA. Cement and petroleum refineries account for nearly all these changes. The results
also show limited impact (within ±10% of EU-27 industrial emissions) on NO
x
and PM emissions. Emission
changes due to electricity import/export are found to be equally important as onsite emission changes.
For the iron and steel sector, the changes in National Emissions Ceilings Directive (NECD) emissions are
found to be limited for the selected CO
2
capture technique under conservative assumptions. However,
the changes in the NECD emissions could vary largely depending on how the steel mill will adapt and
operate their coke oven batteries that supply the coke to the blast furnace (BF).

1. Introduction
Industry and petroleum refineries are among the largest
contributors to anthropogenic CO
2
emissions, accounting for
nearly 40%
1
of these emissions globally (IEA, 2010). Together with
energy efficiency improvement and deploying nuclear energy and
renewables, carbon capture and storage (CCS) is gaining attention
as a promising option to achieve significant reduction of CO
2
emissions in the atmosphere. The potential of CCS in the industrial
and petroleum refining sectors is considered to be significant. The
International Energy Agency (IEA) estimates that, in a scenario to
halve global greenhouse gas (GHG) emissions in 2050 compared
to 2007 level, nearly half of all CCS deployed (up to more than
10 Gt/yr) would be in industrial processes (cement, iron and steel,

and chemicals) and the fuel transformation sector (petroleum
refineries and liquefied natural gas production) (IEA, 2008).
However, CO
2
is not the only substance emitted from the
industrial sector. Since the industrial revolution, power plants and
industries have been a major source of environmental pollution
such as acidification, eutrophication, and toxification of waters.
Large efforts have been conducted by governments and industries
to mitigate these effects. The deployment of (new) technologies
at large scale, such as CCS, should therefore take into account
the possibility of side-effects on other industrial plant emissions.
Therefore, it is important to assess the possible impact of CO
2
capture technologies on the emissions of air pollutants such as
NO
x
, SO
2
, ammonia, non-methane volatile organic compounds
(NMVOC), and particulate matter (PM), which contribute to the
formation of ground-level ozone, and damage ecosystems by acid-
ification and eutrophication. In the European Union (EU), current
emission limits for the first four pollutants are set under the EU
National Emissions Ceilings Directive (NECD) for 2010 (European
Commission, 2001), and all four pollutants are covered by the
Gothenburg Protocol of the United Nations Economic Commission
for Europe to abate acidification, eutrophication, and ground-level
ozone (UNECE, 1999).
