4. History of CNG
• After World War I Muselini in 1914 had ordered for
alternate fuel as such Italy is forefront in CNG
technology and they are the pioneer of CNG
technology. New Zealand, Argentina, Pakistan have
started using the CNG as alternate fuel for
automotive long before that is why many gas standard
& code frame by New Zealand.

5. History of CNG in Bangladesh
• It was 1982 when price of fuel oils jumped in the international
market. In that year Bangladesh had to spend 80 percent of its
total export earnings for importing fuel oils. In Chittagong
BGSL supplying gas from Sangu and Bakherabad gas fields
and having 94.50% of Methane and density around 0.566. The
moisture and other impurities coming along with the gas affect
the performance of machines

6. • CNG being cleanest fuel it has advantage over petrol
and diesel fuel. The engine exhaust of a CNG vehicle
has certain advantages over petrol such as there is no
lead, lower nitrous oxides (NO2) and no organic gas
emission like carbon monoxide (black smoke). Being
the cleanest fuel it eliminates frequent vehicle
maintenance and increases engine oil change
intervals

7. Uses of CNG
Residential use (Cooking, Heating, Air
conditioning etc)
Commercial use (Food Service, hotel,
healthcare facilities)
Industrial use (Paper, Metal, chemical
manufactures etc)
Power generation
Fertilizer (Ammonia- Nitrogen Fertilizer)
Alternative fuel to Gasoline (Compressed
Natural Gas)
Aviation fuel

8. Safety Features
CNG storage cylinders are stronger than petrol tanks since it has been
tested at 5,200 psi pressure and is made of fire resistant chromium and
molybdenum seamless metal structure and fire & bullet proof. CNG has
a specific gravity of 0.587 i.e. lighter than air, if it leaks, it rises up and
dissolves in the atmosphere, while petrol will puddle on the ground
exposing itself to the danger of catching fire

9. Present Situation
there are a lot of refilling stations but not enough CNG-run
vehicles. Out of 19,000 CNG vehicles 10,000 are three-
wheelers, 3,000 taxicabs and 6,000 government and private
cars. The number of CNG-run buses is below 100. Pump
owners said the vehicles they feed each day are not enough to
make their business profitable. Moreover, some other refilling
stations are getting ready to provide service shortly.

10. What's Next
“We'll not wait anymore, we've decided that the RPGCL workshop
will convert the government vehicles. The semi-government and
autonomous bodies will be allowed to convert their vehicles at
private workshops,” said former State Minister for Energy and
Mineral Resources

11. The excellent knock-resistance property of CNG allows use of a
higher compression ratio for increased power output and fuel
economy, compared to petrol. The energy content per kg of CNG
is very similar to that of petroleum-based fuels, but it has lower
energy content per unit of volume. At these high compression
ratios, natural gas-fuelled engines have higher thermal efficiencies
than those fuelled by gasoline. CNG has a higher octane number
than petrol and it is therefore possible for CNG engines to operate
at a higher compression ratio than petrol engines without
knocking.

designed to fill 800 - 1000 Vehicles per day of 16-
18 hours of operation with an average intake of
10-15m3 of gas per vehicle. Huge numbers of
green tri wheelers are also the potential customers
whose average intake is 5 m3 apart from the
taxicab, microbus and car

21. Environmental Aspects
very low particulate emissions
low emission of airborne toxins
negligible SO2 emissions
less noisy operation, with less vibration and less
odors than the equivalent diesel engines.

22. Economic Aspects
• the significantly lower exhaust emissions, especially of particulate matter (PM),
one more major reason for switching to natural gas is to diversify energy sources,
since worldwide natural gas reserves are more abundant than oil reserves. In
2000, the ratio of proven reserves to production of natural gas was estimated to
be 62 years, and that of oil 38 years. A country that imports oil, but has an
abundant supply of natural gas, may find it particularly attractive to consider
natural gas as a transport fuel so as to reduce its oil import bills.

Break Even Point (amount) = Total Fixed Cost/ Contribution Margin (CM)
ratio
= 6,165,120/ 0.43
= 14,337,488.00

26. Limietation of project
lack of operational and maintenance skill
CNG equipment handling
investors having no ideas of highly sophisticated control
system
Performance of the compressor is depends on the inlet
pressure and gas temperature
Difficulty of Gas measurement

27. Recommendations
1 the operator should have through knowledge, comprehensive training
and well conversant with the operational philosophy and logic.
2 the PDB power supply is uncertain and irritant it is recommended to
opt for CNG engine driven compressor.
3 All the compressors are designed for ideal conditions and will never
be able to deliver up-to its full capacity due to various reasons explained
earlier
4 that some sort of set back in each and every machine developed either
due to operational or equipment failure.
5 Gas leak detection is necessary to be included with order as it is not
only requiring for safe operation but also economic point of gas loss
