Main Applications

1. In the chemical industry, ethane is mainly used to produce ethylene through steam cracking. When mixed with steam and heated to 900 ° C or higher, heavy hydrocarbons are cracked into light hydrocarbons, and paraffins become olefins. Compared to other heavier raw materials, a considerable part of ethane becomes ethylene in the steam cracking process, and compounds heavier than it will produce many mixtures, including many heavy olefins such as propylene, butadiene, and aromatic hydrocarbons. Reduce the content of ethylene.

2. Ethane can be used as a refrigerant in refrigeration facilities. In scientific research, liquid ethane is used in electron microscopy to make samples with high water content transparent. The thin layer of water freezes quickly when rapidly immersed in liquid ethane at -150 degrees or lower at the facility without crystal formation. Such rapid freezing does not destroy the structure of soft substances in liquid water, as it does when ice crystals.

Production Process

1. Separation of oil field gas or natural gas from oil field gas In addition to mainly containing methane, it also contains a small amount of ethane, propane or other hydrocarbons with more carbon atoms. The content in natural gas is about 5% to 10%, second only to methane. Isolation yielded ethane. The leachate obtained by cryogenic separation of natural gas is ethane and propane. Butane is a light hydrocarbon mixture whose main component is related to the source of natural gas and the separation and processing temperature and pressure conditions. Typical composition (P) is: 37.6% ethane, 35.9% propane, 11.6% butane Butane 3.9%, n-pentane 3.1%, and other 7.9%.

2. Separation from refinery gas In each refinery petroleum processing gas, in addition to methane, it also contains ethane, propane, and C4 and C5 hydrocarbons. Ethane can be obtained after separation.

3. Separation from cracked gas Ethane can be separated by cryogenic method.
