Write the composition of natural gas prepare a pie chart
Answers
Answer:
Step-by-step explanation:
Our aim is to write the composition of natural gas prepare a pie chart.
We define a natural gas to be found naturally in our surface, that is, that does not have human hand on it. Normally it is composed by some hydrocarbons.
We know that mostly, natural gas is composed by methane. We also can say that 95% of the natural gas is methane, when 3% is only about hydrocarbons, one of them known as propane.
Some other gases are nitrogen, helium and impurities, some are said to be carbon dioxide
Hence this is our composition of natural gas prepare a pie chart.
Pie Chart of Composition of Natural Gas
Natural gas is a gas that is found naturally existing beneath the Earth's surface and is usually composed of mainly hydrocarbons and other non-hydrocarbons.
Natural gas is mainly composed of methane as the main component. Methane accounts for about 95% of the composition of natural gas. Other hydrocarbons like propane account for about 3% of the composition of the natural gas. Other gases include; nitrogen, helium and impurities such as carbon dioxide.
Percentage composition of natural gas by volume:
Hydrocarbons:
Gas %
Methane - 92.7
Ethane - 3.36
Propane - 1.51
Iso-butane - 0.41
Butane - 0.47
Iso-pentane - 0.19
Normal pentane - 0.13
Hexane - 0.27
Inert gases:
Nitrogen - 0.3
Helium - Trace
Impurities
Carbon - 0.59
Hydrogen Sulphide - Trace
Oxygen - Trace
Water - Trace
By using these % values we have a pie chart by composition as given in the following image.
The first step in creating the pie chart would be to cnvert the % to degrees and create the pie chart according the degree.
The main component of the natural gas would be methane with is 95%
95% to degree of the pie chart will be:
95/100 × 360° = 342°
Ethane - 3.36% ⇒ 3.36/100 ×360° = 12.096°
Propane - 1.51% ⇒ 1.551/100 × 360° = 5.436°
