Air Pollution:
The Dirty Truth
-
Introduction
We could live about a month without food. We could even live for several days without water. But without
air, we cannot live more than a few minutes.
We might foul the air so badly in some places that it could become unfit to breath. In some areas, the air is
so bad that people become sick from breathing it, and
some even die because of it.
The World Health Organization estimates that a billion people live in places where the air is substandard and
that air pollution kills 8,000 people a day worldwide.
About 90% of the deaths occur in developing
countries.

Air Pollution
What is it?
Any visible or invisible
particle or gas found in the
air that is not part of the
original, normal
composition.
Natural: forest fires,
pollen, dust storm.
Unnatural: man-made;
coal, wood and other fuels
used in cars, homes, and
factories for energy or
technology processes. 5

5 Major Pollutants:
Carbon Monoxide
Sulfur Dioxide SO2 Nitrogen Dioxide - NO2 Particulate Matter
PM10 (PM 2.5)
Ground Level Ozone
These 5 together form.....
SMOG
Particulate Matter:
- Particles of different sizes and
structures that are released into the
atmosphere
- Present in many sources including
fossil fuels, dust, smoke, fog, etc.
- Can build up in respiratory system
- Aggravates heart and lung disease;
increases risk of respiratory infection

Types and Sources of Air Pollution
Two categories:
Primary Air Pollutant
Harmful substance that is
emitted directly into the
atmosphere.
Secondary Air Pollutant
Harmful substance formed in
the atmosphere when a
primary air pollutant reacts
with substances normally
found in the atmosphere or
with other air pollutants.

9So Where Does Our Air Pollution Come From?
Local emissions in Cities
Reducing local emissions is very important.
Distinct types of transport
We must continue to adopt aggressive local
control measures to reduce the local
contribution.
- Automobile exhaust
- Industrial emissions
- Natural Pollution
Wildfires
Windblown dust
Volcanic eruptions
- Burning of fossil fuels
-
Explanation - Burning of Coal
The coal has a high sulfur content, and emission controls are often inadequate. As a result of burning
of coal, levels of sulfur dioxide and particulate
matter exceeds regular levels more than 10 times.
As China strives to become an industrial power, its people are paying a heavy price in pollution. Coal
burning supplies about of Chinas commercial energy needs.

Burning used motor oil
Waste-derived liquid fuels, or waste oils, are defined as any petroleum-based or synthetic oil that, through use or handling,
has become unsuitable for its original purpose due to the
presence of impurities or loss of original properties. Used
motor oil is an example of waste oil.
11
It is illegal to burn waste oil!
Burning waste oil that contains hazardous
heavy metals or other pollutants.
If you are one of the many people who change their own
motor oil, you too need to know how to properly dispose of
the used oil. Did you know that the used oil from one oil
change can contaminate 4 million liters of fresh water, a
years' supply for 50 people!
Environmental Recycling
-
Burning used car tires
Tire fires exist in two forms: as fast-burning events, leading to almost immediate loss of control, and as slow-burning
pyrolysis which can continue for over a decade.
Such fires produce much smoke, which often carries toxic chemicals from the breakdown of rubber compounds while
burning.
The fire releases a dark, thick smoke that contains carbon monoxide, sulfur dioxide, and products of butadiene and
styrene.
Scrap Tire Fuel Use by Industry.
Environmental Recycling vs Fuel Burning
12It is illegal to burn Scrap Tires!
Burning scrap tires contains hazardous heavy metals or other
pollutants and caused significant environmental damage.

Effects of Air Pollution
15
Air pollution can cause health problems
including burning eyes and nose, itchy
irritated throat, and breathing problems.
Some chemicals found in polluted air can
cause cancer, birth defects, brain and nerve
damage, and long-term injury to the lungs
and breathing passages in certain
circumstances. Above certain concentrations
and durations, certain air pollutants are
extremely dangerous and can cause severe
injury or death.
-
16
Effects
Air pollution can also damage the environment and property. Trees, lakes, and animals have been harmed by air pollution. Air pollution has thinned the protective ozone layer above the Earth.
Air pollution can damage buildings, monuments, statues, and other structures.

Our big problem: Ferro Silicon Industry
"Jugohrom Ferroalloys" LTD JegunovceThe history of "Jugohrom Ferroalloys" LTD - Jegunovce dates back in June, 1952. The Government of the
Republic of Macedonia made a decision to build a company under the name "Factory for chromium
products and ferroalloys" in Jegunovce. In 1953 began the first phase with the building of the plant for
production of chromium compounds. In the following 1954 began the construction of the ferroalloys plant
the production for the market started 1957.
In 2003 the ferrosilicon production was restarted under the name "Silmak, in the beginning of 2012 it withdrew the assets to the company "Metalinvest EFT". In July 2012 in the company "Metalinvest EFT" as a
dominant investor entered in "Camelot Group, brought back the old name in its legal commerce and its market functions as "Jugohrom Ferroalloys".

Ferrosilicon
Ferrosilicon is a ferroalloy, an alloy of iron and silicon with an
average silicon content between 15 and 90 weight percent.
20
Ferrosilicon's with higher silicon
content are made in electric arc
furnaces. This electro-metallurgical
process involves the reduction of
quartz with coke. The usual
formulations on the market are
ferrosilicon's with 15%, 45%, 75%, and
90% silicon. The remainder is iron.
- Ferro-silicon: silicon content of less than 96 %
- Si-metal: silicon content of above 96 %
Ferrosilicon is used as a source of silicon to reduce metals from
their oxides and to deoxidize steel and other ferrous alloys.

Ferroalloy Production
The raw materials that are commonly used for the production
of ferro-silicon and silicon metal:

Emissions to air when producing FeSi alloy
Dioxins (PCDD-F) are a group of polychlorobenzodioxins (PCDDs) and
polychlorodibenzofurans (PCDFs).
PAHs - polycyclic aromatic hydrocarbons. A number of PAHs have caused tumors in
laboratory animals that were exposed to PAHs them.
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids.
VOCs include a variety of chemicals, some of which may have short- and long-term adverse
health effects.Source: 226 Nordic Report 2008

Emissions to air when producing FeSi alloy
The main environmental impacts of storage and handling of these
materials are diffuse dust emissions and the contamination of surface
water and soil caused by wash out from rainwater.
Particulate is generated from several activities during ferroalloy production, including raw material handling, smelting, tapping, and
product handling. Organic materials are generated almost exclusively
from the smelting operation. The furnaces are the largest potential
sources of particulate and organic emissions.
Emission factors are expressed as kg of pollutant/metric tone alloy
produced:
Product : FeSi (75%) (SCC 3-03-006-02)
Furnace Type:
Open 158 kg of pollutant/metric tone alloy produced
Covered 103 kg of pollutant/metric tone alloy produced

Emissions to air when producing FeSi alloy
Installed power of Jugohrom is 120MWh, for 70MWh (60% of capacity)
electricity demand of electric arc furnaces, we can calculate approximately:
- Daily electricity consumption is arrond 1,500MWh
- Production of FeSi alloy 160mt
- Consumption of quartz (SiO2) 290mt
- Coke - 190mt
- Particulate is generated during this amount of ferroalloy production
25mt daily
- Organic materials are generated almost exclusively from the smelting
operation.

Producing FeSi alloy with filters
A baghouse (BH, B/H) or fabric filter (FF) is an air pollution control device that
removes particulates out of air or gas released from commercial processes or
combustion for electricity generation.
Melting point (C) 1320
31
Particulate matter (also
referred to as soot or fly ash)
can capture as much as 99%
of the particulates.
About 80 to 90 percent of fly
ash, bottom ash and boiler slag
is non-radioactive minerals,
typically silicon, aluminum, iron
and calcium.
