Ethane is a hydrocarbon component of natural gas, a fossil fuel
Ethane (C2H6) is a hydrocarbon component of natural gas, which is a fossil fuel. It is a naturally occurring organic chemical compound. At standard temperature and pressure, ethane is a colorless, odorless gas. Ethane is isolated on an industrial scale from natural gas and as a petrochemical byproduct of petroleum refining.
Natural gas is composed of about 80% methane, with varying proportions of other compounds, including ethane, propane, and butane. It is used as a fuel, and ethane can be burned to generate heat energy. The combustion of ethane combines it with oxygen to form carbon dioxide and water, as shown in the chemical equation:
2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O) + Heat Energy
Ethane is also a trace gas in the Earth's atmosphere, with a concentration of 0.5 ppb at sea level. Its presence in the atmosphere is influenced by emissions from fossil fuels and biomass burning. While ethane emissions from fossil fuels peaked in the 1960s and 1970s, they have since declined. This decline is likely due to changes in light hydrocarbon emissions associated with petroleum production and use.
Ethane has become an increasingly important fossil fuel in recent years, particularly in the United States. It is now a valuable feedstock for plastics production and is exported to chemical companies worldwide. The development of ethane as a fossil fuel resource has been described as "extraordinary" and a significant advancement in the shale revolution.

Ethane is a colourless, odourless gas
Natural gas is a fossil fuel that is formed when layers of organic matter, primarily marine microorganisms, are thermally decomposed under oxygen-free conditions. It is composed primarily of methane, a colourless and odourless gas, and small amounts of other hydrocarbons. Ethane is one of these natural gas liquids (NGLs) that are separated from the wet gas during processing. Therefore, ethane is a colourless and odourless gas.
Natural gas is found in underground geological formations, often alongside other fossil fuels like coal and oil. It can be extracted from the ground and is used for heating, cooking, and electricity generation. It is considered the cleanest-burning fossil fuel and produces fewer toxic air pollutants and less carbon dioxide compared to other fossil fuels. However, natural gas contributes to climate change as it contains methane, which is a powerful greenhouse gas.
Methane (CH4) is the primary component of natural gas and is responsible for about a third of the warming experienced today. It has a much higher global warming potential than carbon dioxide, with a lifetime of about a decade in the atmosphere. While methane has a shorter lifespan than other greenhouse gases, it is more efficient at trapping heat. Human activities, such as the extraction, storage, transportation, and distribution of fossil fuels, contribute significantly to methane emissions.
To address the environmental concerns associated with methane, there has been a focus on reducing emissions and transitioning to renewable sources. Renewable natural gas (RNG), also known as biomethane, is produced by purifying biogas through the anaerobic digestion of organic materials. RNG is chemically identical to fossil-derived natural gas, allowing it to utilize the existing distribution system. By increasing the use of RNG and implementing emission reduction measures, we can mitigate the impact of methane on climate change and work towards a more sustainable future.

Ethane is feedstock for US plastics production
Ethane is a naturally occurring organic chemical compound with the chemical formula C2H6. At standard temperature and pressure, ethane is a colourless, odourless gas. Ethane is a fossil fuel emitted from natural gas, which contains varying proportions of methane, propane and butane. It is also emitted from biomass burning.
Ethane is a key building block of plastics. It is an attractive feedstock for plastics because it is chemically efficient and inexpensive, allowing plastics to be manufactured more profitably.
In the United States, ethane is produced through natural gas fracking. The increased availability of wet natural gas has led to the use of natural-gas-based feedstocks in place of traditional liquids from petroleum processing.
Shell is building a $6 billion ethane cracking plant in Monaca, Pennsylvania. The plant will turn ethane into ethylene, a building block for many kinds of plastic. It is expected to produce up to 1.6 million tons of plastic annually.
The use of ethane as a feedstock for plastics production has raised environmental concerns. Despite efforts to reduce plastic use, demand is continuing to grow rapidly, leading to an anticipated increase in plastic pollution.

Ethane emissions from fossil fuels peaked in the 1960s and 1970s
Natural gas, which consists mainly of methane, is a fossil fuel. It is found in underground geological formations, often alongside other fossil fuels like coal and oil. Natural gas is used for heating, cooking, and electricity generation.
Ethane and methane are the most abundant hydrocarbons in the atmosphere, and they affect both atmospheric chemistry and climate. Both gases are emitted from fossil fuels and biomass burning. Ethane emissions from fossil fuels peaked in the 1960s and 1970s at 14-16 teragrams per year (1 Tg = 10^12 g). This peak was followed by a decline over the next 20 years, with emissions dropping to 8-10 Tg yr^-1 by the turn of the century. The reduction in fossil fuel sources is likely related to changes in light hydrocarbon emissions associated with petroleum production and use.
The variability in ethane emissions during the twentieth century was primarily driven by changes in emissions from fossil fuels. While ethane levels rose from the early 1900s until the 1980s, a reversal in the trend occurred in the latter year, leading to a decline over the subsequent two decades. This variability was influenced by factors such as petroleum production and use, as well as emissions from wetlands, agriculture, landfills, and wastewater.
Methane is a significant greenhouse gas that contributes to global climate change. It has a notable warming effect on the climate, surpassed only by water vapour and carbon dioxide. While methane has a shorter lifespan in the atmosphere compared to other greenhouse gases, it is more efficient at trapping heat. Human activities, such as the extraction, storage, transportation, and distribution of fossil fuels, are responsible for a significant portion of methane emissions.

Ethane was discovered in 1864 by Edmund Ronalds
Ethane is a naturally occurring organic chemical compound with the chemical formula C2H6. At standard temperature and pressure, ethane is a colorless and odorless gas. It is isolated on an industrial scale from natural gas and is a petrochemical by-product of petroleum refining. Ethane was first synthesized in 1834 by Michael Faraday, who applied electrolysis to a potassium acetate solution. However, he mistook the product of this reaction for methane.
In 1864, Edmund Ronalds, an English academic and industrial chemist, discovered ethane dissolved in Pennsylvanian light crude oil. Ronalds ran the Bonnington Chemical Works, where residues from the manufacture of coal gas at the Edinburgh gasworks were processed into valuable products. During his time at Bonnington, Ronalds isolated several simple hydrocarbons, including ethane, propane, and butane, and described their properties. He also co-authored a series of books on chemical technology, which helped initiate university teaching of chemical applications for industry.
Prior to Ronalds' discovery, chemists Hermann Kolbe and Edward Frankland produced ethane during the period 1847-1849 through the reductions of propionitrile (ethyl cyanide) and ethyl iodide with potassium metal. They also achieved this by applying electrolysis, as Faraday had done. In 1864, Carl Schorlemmer corrected Faraday's mistake and showed that the product of his reaction was, in fact, ethane.
Ethane is a greenhouse gas and a fossil fuel emission. It occurs as a trace gas in the Earth's atmosphere, with a concentration at sea level of 0.5 ppb. Global ethane quantities have varied over time, likely due to flaring at natural gas fields. Ethane emission rates declined from 1984 to 2010, although increased shale gas production at the Bakken Formation in the U.S. has since slowed this decline.
