| Description |
Ethanol is a chemical compound that is made up of three basic
elements i.e. carbon, hydrogen and oxygen having the empirical
formula C2H6O. This mild intoxicating agent
has no color and taste but definitely a distinctive smell and is
flammable also. Ethanol, also known by the names ethyl alcohol or
grain alcohol, is used primarily as a significant ingredient in
alcoholic beverages and as a fuel. Ethanol is also considered as a
clean-burning added feature to gasoline. To produce this chemical,
either sugar from the various agricultural crops are fermented or
it is produced chemically with the help of ethylene.

Overview |
Ethanol is chemically an important compound as the range of uses
that it provides is quite wide. Also, the chemical has got some
unique physical properties that makes it even more viable
constituent in various other uses. Ethanol is an easily soluble
component, and when mixed with water, it reduces the surface
tension of water. The main demand of ethanol arises from the
transport sector as the chemical provides an efficient fuel when
mixed with petrol. This use of ethanol has been discovered quite
recently and all the countries in the world have started mandating
the use of ethanol mixed petrol in all types vehicles including
rockets. Also, ethanol has been used in the fermented and
distilled alcoholic beverages since a long time that include
whiskies, brandies, rum, vodka and beers. Chemicals like nail
polish, vinegar, agricultural chemicals etc are also made by using
ethanol.
The world production in ethanol summed up to 10770 million
gallons in 2004. The leading producing country in the list was
Brazil contributing approximately 37% in the world production. The
country is followed by United States of America and China at the
2nd and 3rd place respectively. With the introduction of new
technology, and the discovery of many more uses of ethanol, the
production is required to rise as it has been rising since the
past years. World consumption figures are estimated to cross the
25 million tons mark in 2006. The consumption has also been
increasing gradually with time and would grow @ 2 or 3% making the
global ethanol market worth over $16 billion by 2005. The main
ethanol consuming countries are
- Brazil
- USA
- India
- European Union
- Japan
- Mexico
- China
- Korea
- Thailand
Regarding the world trade in the context of
ethanol, the major player is European Union as it is the major
exporter of the chemical compound. World estimated trade figures
for the year 2006 is calculated to be around 2.5 million tons with
the leading countries in the ethanol exporters list are
-
European Union
-
United States
-
Brazil
-
China
-
Thailand
-
France
-
South Africa
-
United Kingdom

History
|
The history of ethanol dates back to the
prehistoric times when it was used as an
intoxicating ingredient in alcoholic beverages.
The question that how did ethanol originate is
yet to find its answer but the archeological
findings as old as around 9000 years that were
found in northern China suggest that even the
people in the last part of Stone Age used to
consume ethanol as alcohol. But it is clear that
the people then didn’t know about the
existence of ethanol in their alcohol.
Islamic alchemists first recognized the
compound in a relatively pure form as they found
out the process of distillation. They wrote and
published several writings on the distillation
of wine and extracting ethanol and also about
the mixture of ethanol and water. But ethanol in
its absolute form was never obtained until in
1796 when Johann Tobias Lowitz filtered the
already distilled ethanol with the help of
charcoal. After the pure form of ethanol was
invented, the research work on the chemical got
speed and in the beginning of 1800s, Antoine
Lavoisier discovered that ethanol is a compound
of carbon, hydrogen and oxygen. Its chemical
formula was determined in 1808 and structural
formula in 1858 making it one of the first ever
compounds to have their chemical structures
determined. Henry Hennel in Great Britain
discovered the method of obtaining ethanol
synthetically in 1826.
In the 19th century, ethanol grew popular and
became one of the major lighting fuels in the
world. It was vastly used and that is why, it
looked appropriate to impose taxes on it to
raise funds during the civil war in America.
With time the other uses of ethanol were also
discovered and the main use proved out to be as
a fuel. In 1906, Henry Ford termed ethanol as
the fuel of the future.

| Ethanol producing countries |
Production of ethanol involves a complicated and a
systematic procedure. As mentioned earlier,
ethanol can be produced by two ways either
biologically or chemically
- Fermentation - The traditional and the most
commonly used method of preparing ethanol is
the biological method in which the sugars of
various agricultural crops like sugarcane,
corn, wheat, barley, cassava, rice, grains,
sugarcane, sweet sorghum, sugar beet, rye are
fermented with yeast. The process of growing
yeast to produce alcohol is called brewing.
This process is capable of producing only
small amounts of ethanol.
- Ethylene hydration – This is the second
method of producing ethanol in which ethylene
is hydrated with the help of an acid catalyst
usually phosphoric acid. Charcoal is also an
important component that helps in the
hydration process and extracting ethanol.
The result of either of the
above two processes is ethanol – water mixture
that must be purified before use. The
processes of fractional distillation is performed
to concentrate the ethanol content and then drying
of ethanol is done with the help of lime, salt,
molecular sieve etc which brings it to its purest
form.
The world production of
ethanol in 2004 was summed up to 10770 million
gallons. The largest ethanol producer country is
Brazil followed by United States of America and
China. The list depicting the largest ethanol
producers of the world with their production
figures are
-
Brazil (3989 million
gallons)
-
USA (3535 million
gallons)
-
China (964 million
gallons)
-
India (462 million
gallons)
-
France (219 million
gallons)
-
Russia (198 million
gallons)
-
South Africa (110 million
gallons)
-
United Kingdom (106
million gallons)
-
Saudi Arabia (79 million
gallons)
-
Spain (79 million

Production of
ethanol in India
India is the fourth largest producer of ethanol
in the world and the second largest producer in
Asia after China. The country produces around 460
million gallons of ethanol annually contributing
approximately 4% to the world total production.
Though India produces such large quantities of
ethanol, still it has the capacity to produce even
larger quantities of around 713 million gallons
per year. That is why it can be said that the
utilization rate in the country is usually low.
There are only 10 ethanol plants that exist in
India and 20 more ethanol plants are proposed to
be constructed in the near future to cope up with
the increasing demand. Most of the plants are
located in the states of
- Uttar Pradesh
- Maharashtra
- Tamil Nadu

| Indian
ethanol market
|
In India, ethanol is not traded in the commodity
exchanges like the other commodities even though the
country is a significant player in the world market.
India has got potential of becoming one of major
player in the world ethanol market as it has ample
capacity to produce the chemical compound almost
double of its current produce. But due to a lower
utilization rate, India has to constrain its
production level. The current production of the
chemical in the country hovers around 460 million
gallons annually, the maximum contribution being done
by Uttar Pradesh as it has got the highest number of
ethanol plants in the country among the 10 existing
plants. The production of ethanol in the country has
been increasing and is estimated to increase further
in the future.
Likewise, the consumption of ethanol has also been
increasing in the past and it is believed that the
consumption figures would cross the 22-lakh tons mark
in 2006. The use of ethanol in petrol has proved to be
advantageous as it enables a good combustion and that
is why, the use of petrol with 5% ethanol content (E5)
has been made compulsory by the government. Also the
consumption of the petrol with a raised ethanol
content of 10% (E10) is still under thought. The
ethanol that is required for the preparation of E5
blend petrol is around 98 million gallons annually.
The country also exports some quantities of ethanol
and stands at the 6th place in the list of leading
exporting countries. The estimated figures for the
Indian ethanol exports for the year 2006 are around
70000 tons.
