Why Choose Ethane as Feedstock for Ethylene Production?


Ethane is one of the most abundant hydrocarbons found in natural gas reserves. Its availability makes it a cost-effective and reliable source for ethylene production.

High Ethylene Yield

When high quality ethane gas undergoes steam cracking, it produces a high yield of ethylene, typically over 90%. This high conversion efficiency makes it an efficient feedstock.

Energy Efficiency

Ethane cracking is an energy-efficient process due to its lower molecular weight compared to other feedstocks like naphtha or propane. It requires less energy to break down ethane molecules into ethylene.


High quality ethane gas is often a purer hydrocarbon compared to other feedstocks, which may contain impurities that can complicate the cracking process. This purity contributes to more consistent and reliable production.

Lower By-Product Formation

High quality ethane gas cracking generates fewer undesirable by-products compared to other feedstocks, reducing the complexity of downstream separation and purification processes.


Ethane is generally cost-competitive as a feedstock due to its abundance and relatively low market price compared to alternative feedstocks like naphtha or propane.

Environmental Benefits

While all feedstocks have environmental impacts, ethane is considered to have a lower carbon footprint compared to feedstocks like coal or heavy crude oil. This can align with sustainability and emissions reduction goals.


Ethane cracking facilities can be designed to be versatile, allowing for the switch to alternative feedstocks if market conditions or availability change. This flexibility enhances the resilience of ethylene production processes.

Consistent Quality

Ethane's consistent composition and purity make it easier to maintain quality control in the production of ethylene and downstream products.
