Natural gas is an essential source of energy that is used for heating, cooking, and generating electricity. However, natural gas is not usable in its raw form, and it must go through a series of processes to become usable. In this article, we will explore how natural gas is made usable and the different methods used.
Exploration and Extraction
The first step in making natural gas usable is exploration and extraction. Natural gas is found deep within the earth’s crust and is extracted by drilling wells into the ground. Once the well is drilled, a process called hydraulic fracturing or “fracking” is used to extract the natural gas. Fracking involves injecting a mixture of water, sand, and chemicals into the well at high pressure. This process fractures the rock layer, allowing the natural gas to flow more freely.
After the natural gas is extracted, it is transported to processing plants through pipelines. The pipelines transport the natural gas from the wellhead to the processing plant, where it is cleaned and processed.
Processing and Purification
The second step in making natural gas usable is processing and purification. Once the natural gas arrives at the processing plant, it goes through a series of processes to remove impurities and increase its energy content. The first step in processing natural gas is to remove any water or liquids that may be present. This is done by using a process called dehydration, which involves passing the natural gas through a series of filters to remove any water or liquids.
After dehydration, the natural gas is passed through a series of processing units, where it is purified and the energy content is increased. The first processing unit is the acid gas removal unit, where any acid gases, such as carbon dioxide and hydrogen sulfide, are removed. The next unit is the sulfur recovery unit, where the sulfur is removed from the natural gas. Finally, the natural gas is passed through a unit called the cryogenic unit, where it is cooled to a temperature of -162°C (-260°F) to separate any remaining impurities.
Once the natural gas has been processed and purified, it is ready for distribution to consumers. Natural gas is transported through pipelines to power plants, homes, and businesses, where it is used for heating, cooking, and generating electricity.

Conversion to Usable Energy
The third step in making natural gas usable is converting it to energy. Natural gas can be converted into usable energy in several ways, including combustion, steam reforming, and fuel cells. The most common method of converting natural gas to energy is through combustion. Combustion involves burning natural gas to generate heat, which can then be used for heating or to generate electricity.
Another method of converting natural gas to energy is through steam reforming. Steam reforming is a process that involves reacting natural gas with steam to produce hydrogen gas, which can then be used in fuel cells to generate electricity. Fuel cells are an efficient and clean way to produce electricity from natural gas, with minimal emissions.
While natural gas is a cleaner burning fuel than coal or oil, it still has an environmental impact. The extraction and processing of natural gas can have negative effects on the environment, such as air and water pollution. The fracking process can contaminate groundwater and release toxic chemicals into the air.
In addition, natural gas is a potent greenhouse gas, with a global warming potential 84 times greater than carbon dioxide over a 20-year period. While natural gas is a cleaner burning fuel than coal or oil, it still contributes to climate change.
To mitigate the environmental impact of natural gas, efforts are being made to reduce emissions and increase efficiency. Technologies such as carbon capture and storage and renewable natural gas are being developed to reduce the environmental impact of natural gas.
In conclusion, natural gas is an essential source of energy that is used for heating, cooking, and generating electricity. To make natural gas usable, it must go through a series of processes, including exploration and extraction, processing and purification, and conversion to usable energy. While natural gas is a cleaner burning fuel than coal or oil, it still has an environmental impact. Efforts are being made to reduce emissions and increase efficiency to mitigate the environmental impact of natural gas. As consumers, it is essential to be aware of the environmental impact of natural gas and to make informed choices about our energy use.
Advantages of Using Natural Gas
There are several advantages to using natural gas as an energy source. One of the biggest advantages is its cost-effectiveness. Natural gas is relatively inexpensive compared to other energy sources, such as oil and coal. This makes it an attractive option for businesses and homeowners looking to save money on their energy bills.
Another advantage of natural gas is its cleanliness. Natural gas is a clean-burning fuel that produces fewer emissions than other fossil fuels. This makes it an environmentally friendly option and reduces the impact of greenhouse gases on the environment.
Finally, natural gas is a reliable energy source. Unlike wind and solar power, which are dependent on weather conditions, natural gas can be used consistently, regardless of the weather. This makes it a reliable option for businesses and homeowners who need a consistent source of energy.
In conclusion, natural gas is a valuable energy source that is used for heating, cooking, and generating electricity. However, natural gas is not usable in its raw form and must go through a series of processes to become usable. The exploration and extraction process involves drilling wells and using fracking to extract the natural gas. The processing and purification process involves removing impurities and increasing the energy content of the natural gas.
Despite the challenges of making natural gas usable, there are several advantages to using it as an energy source. Natural gas is cost-effective, clean, and reliable, making it an attractive option for businesses and homeowners. As we continue to explore new ways to use natural gas, we can expect to see it become an even more important part of our energy mix in the future.
