When we think of gases, the first things that come to our mind are probably oxygen and carbon dioxide. But did you know that there are other gases out there that we should also be paying attention to? One example is ethane gas. Ethane is a colorless and odorless gas commonly found in natural gas. It may not get as much attention as other gases, but its impact on our planet should not be overlooked.
Another gas that we should be aware of is methane. Methane is a potent greenhouse gas that is produced by both natural and human activities. It is estimated to be responsible for around 20% of the global warming that we are experiencing today. The sources of methane emissions include fossil fuel production, rice cultivation, and livestock farming. With the ever-increasing global demand for energy and food, it has become more important than ever to address the issue of methane emissions.
While we may not be able to completely eliminate the use of ethane and methane gases, we can take steps to reduce their impact on our environment. By adopting sustainable practices like renewable energy and reducing waste, we can help to mitigate the harmful effects of these gases. It’s time for us to take action and work towards a cleaner and more sustainable future for ourselves and future generations.
Natural gas composition
Natural gas is a mixture of different gases, but it mainly consists of two primary hydrocarbons, ethane, and methane. These gases naturally occur and are commonly found in coal seams, shale rock, and other geological formations. The two hydrocarbons have different chemical formulas, with ethane having a C2H6 formula, and methane having a CH4 formula.
- Ethane: Ethane is a colorless and odorless gas that forms a part of natural gas. It is the second most abundant component in natural gas, after methane. Apart from natural gas, ethane is also found in crude oil, condensates, and petrochemicals. It is generally used as a fuel gas for heating and industrial purposes.
- Methane: Methane is a colorless and odorless gas that has a lower heating value but a higher calorific value than ethane. Methane is the primary component of natural gas, accounting for up to 98% of the gas. It is also found in coal mines and oil fields. Methane is widely used as a fuel source in the transportation sector, as well as in the generation of electricity and heat.
The composition of natural gas from one location to another can vary widely, but it primarily contains varying amounts of methane, ethane, propane, butane, carbon dioxide and nitrogen. However, the composition of natural gas depends on several factors, including the location of the gas field, the depth of the well, and the geological formation of the field.
A typical composition of natural gas would contain the following gases in the given percentages:
| Gas Name | Percentage composition |
|---|---|
| Methane | 80%-94% |
| Ethane | 0-20% |
| Propane | 0-10% |
| Butane | 0-8% |
| Carbon dioxide | 0-10% |
| Other gases | 0-8% |
The variation in composition affects the heating value of the gas, and therefore has implications in its use as a fuel source. While methane has a high heating value and is preferred, the other gases such as propane, butane and other hydrocarbons can vary the heating value and cause inefficiencies in its usage as a fuel.
Conclusion
Natural gas composition is diverse across the globe, which has implications for its use as a fuel source. Recognizing the different compositions of the gas should be a key consideration for stakeholders in the gas industry. Proper handling of natural gas composition will allow for optimal utilization of the fuel source, increasing energy efficiency, and cutting down on environmental impacts.

Extraction of Ethane and Methane
Ethane and methane are both natural gases that are used widely across the globe in various applications. They are extracted primarily from the earth’s crust, where they are found in abundance in the form of shale rock. In this article, we will discuss the different methods used for the extraction of ethane and methane from the shale rock.
1. Hydraulic Fracturing
Hydraulic fracturing, commonly known as fracking, is the most commonly used method for extracting ethane and methane from shale rock. It involves pumping a mixture of water, sand, and chemicals into the shale rock at high pressure, which causes the rock to fracture and release the gas. The gas then flows up through the well to the surface, where it is collected and processed.
2. Horizontal Drilling
Horizontal drilling is another method used for extracting natural gas. In this method, a well is drilled vertically into the shale rock and then turned horizontally to follow the shale layer. Once in the shale layer, a mixture of water, sand, and chemicals is pumped into the rock to release the gas, which is then collected and processed.
3. Coal Bed Methane Extraction
Coal bed methane is another form of natural gas that is extracted from coal seams. The process involves drilling a well into the coal seam and pumping water into the seam to release the gas. The gas is then collected and processed.
4. Gas Hydrate Extraction
Gas hydrates are another potential source of natural gas. They are formed when methane gas becomes trapped in ice crystals. Extraction involves drilling into the sediment of the seafloor or permafrost and injecting warm water or a mixture of chemicals into the hydrate to release the gas. The gas is then collected and processed.
5. Underground Coal Gasification
Underground coal gasification is a newer extraction method that involves burning coal underground and collecting the resulting gas. The process is still in its experimental stages and is not widely used.
6. Flaring and Venting
- Flaring: Flaring is the process of burning off excess gases that cannot be processed. This is commonly seen at oil and gas wells where the amount of natural gas produced exceeds the capacity of the processing plant. Flaring is also used for emergency situations, such as when a well becomes over-pressurized.
- Venting: Venting is the intentional release of natural gas into the atmosphere. This is typically done during well testing or maintenance activities. Venting is harmful to the environment and is not a preferred method of natural gas extraction.
Conclusion
The extraction of ethane and methane is a complex process that involves a variety of methods. Hydraulic fracturing is the most commonly used method for extracting natural gas, followed by horizontal drilling. Coal bed methane and gas hydrate extraction are other methods used for extracting natural gas. Underground coal gasification is a newer method that is still in the experimental stage. Flaring and venting are not preferred methods of natural gas extraction due to their harmful effects on the environment.
