Natural Gas Natural gas is composed primarily of methane found in large underground deposits. It is used widely as an energy source. Historically, natural gas was first discovered being released from lakes and used in lighting in the early 1800s. It is extracted through drilling operations and transported through pipelines. Major applications include electricity generation, industrial processes like manufacturing and chemicals, residential heating and cooking, and commercial uses. While natural gas produces fewer emissions than coal or oil, drilling and transportation can impact the environment if not properly regulated. Overall, natural gas has significant economic benefits and produces fewer greenhouse gas emissions than other fossil fuels.

4. Introduction.
What is natural gas?
• Natural gas is composed of hydrocarbons (combinations
of hydrogen and carbon).
• 89-93% methane gas, the lightest hydrocarbon.
• Plus other gases such as ethane, propane, butane, and
non-flammable gases such as nitrogen and carbon
dioxide.

5. Introduction.
Properties of natural gas.
Natural gas is 96% Methane gas – CH4
Also contains small percentages of:
• Ethane -2.1%
• Propane <1%
• Butane <1%
• Pentan <1%
• Hexane <1%
• Heptane <1%

6. Introduction.
Where is natural gas found?
• In some places, natural gas moved into
large cracks and spaces between layers of
overlying rock.
• The natural gas found in these types of
formations is sometimes called
conventional natural gas.

11. History
• In 1626 by Frences explorers who notice that
the native American igniting gas,that seeped
from lake erie.
• Around 1785 the first commercialized natural
gas occurred at Baltimore,Maryland city in
Britain.

12. History
• In 1885 Robert Bunsen’s invention of what
is now known as the Bunsen burner opened
bast new opportunities to use natural
gas.And that the natural gas used almost
exclusively as a source of light.

21. Application.
Application of Natural Gas in Bangladesh.
i. Electric power generation,
ii. Industry,
iii. Residences and
iv. Commercial
Were the major natural gas consuming sectors in
Bangladesh during calendar year 2021.

22. Application.
i. Power Sector.
The electric power sector uses natural gas to
generate electricity and produce useful thermal
energy to maintain-
• Boiler
• Steam turbines
• Gas turbines.

23. Application.
ii. Industrial Application.
The industrial sector uses natural gas-
• Fuel for Manufacturing process and process
heating ,
• Heat and power systems,
• Produce chemicals,
• Fertilizer,
• Medicine,
• Fibers and plastics etc.
Fig:Industry section

24. Application.
iii. Residential Application-
The residential sector uses natural gas
• To heat buildings and water,
• To cook, and
• To dry clothes

25. Application.
iv. Commercial Applicatin.
The commercial sector uses natural gas to-
• Heat buildings and water,
• To operate refrigeration and cooling equipment,
• To cook,
• To dry clothes, and
• To provide outdoor lighting.

26. 5. Environmental Effect.
Describe By : Ananda Bala(198027)

27. Environmental Effect.
Now a days natural gas environmental effect is a
debating topic for scientist.Let’s talk about it.
• Five environmental benefites of natural gas.
i. Natural gas is the cleanest fossil fuel,for that less
environment affect.
ii. Because of simple chemical composition of natural gas
there are less pollution.
iii. Natural gas produces less chemicals than oil and coal.
iv. Natural gas is use as clean energy source.
v. Approximately 90% of natural gas converted for energy,so
that natural gas produce less waste.

28. Environmental Effect.
How does natural gas affect the environment?
• Natural gas environmental impact is based on 3 pillars:
i. Drilling and extraction.
ii. Transportation.
iii. Burning and consumption.
Fig:Natural gas extraction.

29. Environmental Effect.
Natural gas environmental benefits.
• Statistics prove that there are many benefits of
natural gas.
• We can see here natural gas produce less
amount af CO2,compared another fuel.
Fig:Statistics about CO2 produce (kg/kWh)

30. 6.Conclusion.

31. Conclusion.
Every fossil fuel extraction is bad for the environment but it increases our
economic footprint.
• But the question “Is natural gas the most eco-friendly fossil fuel?”
The answer is “yes”.
Because-

32. Conclusion.
We also seen-
• Natural gas emits 52-
56%less greenhouse than
coal.
• Only 2% responsible for
greenhouse.
• From 1990 in the U.S.
natural gas production
increase 37%,but
greenhouse gas decrease
17%.
