Ethane is a hydrocarbon, an odorless and colorless gas that is produced as a byproduct when natural gas is processed or refined. It is primarily used to produce ethylene, propylene, and other petrochemical products. The lightest of the alkanes, ethane has many applications in various industries. This article explores what ethane is, its uses, properties, production methods, and more. Keep reading to find out everything you need to know about this versatile hydrocarbon.
What is Ethane?
Ethane is a hydrocarbon fuel primarily used to produce ethylene, propylene, and other petrochemical products. It is the most abundant hydrocarbon in the world, and the third simplest molecule after hydrogen and methane. Unlike most alkanes, ethane is naturally occurring, allowing for ethane extraction as a byproduct when processing or refining natural gas. Ethane can also be synthesized from crude oil and from coal through hydrogenation. Ethane is colorless and odorless, and is widely distributed in nature. It has many applications in various industries, like petrochemicals, natural gas processing, agriculture, and energy. Ethane is primarily used to produce ethylene, propylene, and other petrochemical products.
Properties of Ethane
Pure ethane has a heat of combustion of 25.5 MJ/kg, a flash point of -92 °C, an atmospheric boiling point of -88 °C, a specific gravity of 0.5, a vapor pressure of 99.3 kPa at 20 °C, and a viscosity of 0.1 Pa·s at 20 °C. The viscosity of ethane depends on the pressure and temperature at which it is measured. Ethane is relatively soluble in water and most common organic solvents. It is also miscible with ethanol, which is used as a solvent in ethane extraction. When ethane gets in contact with the atmosphere, it undergoes oxidation, producing CO2 and methane. Ethane is highly flammable, with a flammability limit of 10%. It is also inflammable, with a flash point of -18 °C.
Uses of Ethane
Ethane is primarily used to produce ethylene, propylene, and other petrochemical products. It is also used to produce ethylene oxide, ethylene glycol, ethanol, carbon dioxide, and hydrogen. Ethane is also used as an alternative fuel and a fuel additive. Ethane is a feedstock for the production of ethylene, a major building block for the petrochemical industry. Approximately half of the ethylene produced in the U.S. is used to make polyethylene, which is used to make plastic bags, bottles, wrap, and other packaging materials. Ethylene is also used to make a wide range of other chemicals. Ethane is also used as a fuel. Ethane is used in place of natural gas in some areas, and it can also be blended with other fuels to reduce emissions. Ethane can also be used to make ethanol, which is used as a fuel in certain vehicles. Ethane is also used as an additive to improve the performance of fuels in engines.
How is Ethane Produced?
Ethane is naturally produced as a byproduct when processing or refining natural gas. Ethane can also be obtained by hydrogenation of crude oil and coal, or through hydrogenolysis of ethylene. In North America and Europe, ethane production is primarily used to produce ethylene, propylene, and other petrochemical products. Ethane is synthesized from crude oil and coal through hydrogenation. These processes involve the catalytic conversion of ethane with hydrogen to produce ethylene or ethylene derivatives. In the hydrogenation process, the high pressure and temperature are needed for ethane conversion. Ethane can also be obtained by fractional distillation of natural oil and natural gas.
Supply and Demand of Ethane
The supply of ethane is expected to outpace demand over the next decade. Ethane supply is expected to increase by over 10 million tonnes per year from 2020 to 2030, due primarily to increased ethane production from natural gas processing. Ethane demand is expected to remain relatively stable. Ethane is used as a feedstock for ethylene and ethylene derivatives, a feedstock for the production of ethylene oxide, and as a fuel additive. Ethane demand is expected to increase in the near term due to increased ethylene and ethylene derivative production. Ethane demand is expected to decrease in the long term as ethylene production moves away from ethane feedstock. Ethane is expected to remain in surplus over the next decade.
Conclusion
Ethane is a hydrocarbon that is largely produced as a byproduct when processing or refining natural gas. Ethane is primarily used to produce ethylene, propylene, and other petrochemical products. Ethane is also used as an alternative fuel or a fuel additive and as a feedstock for ethylene and ethylene derivatives. The supply of ethane is expected to outpace demand over the next decade. Ethane supply is expected to increase by over 10 million tonnes per year from 2020 to 2030, due primarily to increased ethane production from natural gas processing.
