  2. Steam cracking - Wikipedia

    en.wikipedia.org/wiki/Steam_cracking

    Steam cracker process diagram Gibbs free energy per carbon atom. This shows that at high temperature, hexane can split into ethane and ethylene ("Ethen"), and ethane can split into ethylene and hydrogen. But ethylene can decompose into methane and carbon if given too much time, and all the hydrocarbons can decompose into carbon and hydrogen.

  3. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    The chief use of ethane is the production of ethylene (ethene) by steam cracking. Steam cracking of ethane is fairly selective for ethylene, while the steam cracking of heavier hydrocarbons yields a product mixture poorer in ethylene and richer in heavier alkenes (olefins), such as propene (propylene) and butadiene, and in aromatic hydrocarbons.

  4. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    Two extremes of the thermal cracking in terms of the product range are represented by the high-temperature process called "steam cracking" or pyrolysis (ca. 750 °C to 900 °C or higher) which produces valuable ethylene and other feedstocks for the petrochemical industry, and the milder-temperature delayed coking (ca. 500 °C) which can produce ...

  5. Mossmorran - Wikipedia

    en.wikipedia.org/wiki/Mossmorran

    Ethane is mixed with superheated steam and heated to 800-900°C in seven cracking furnaces to crack it into ethylene (ethene) (C 2 H 4 or H 2 C=CH 2). The ethylene mixture is then cooled to 25°C in a series of heat exchangers and finally routed to a quench tower where water cascades down through the gas to remove by-products such as tar.

  6. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene is produced by several methods in the petrochemical industry. A primary method is steam cracking (SC) where hydrocarbons and steam are heated to 750–950 °C. This process converts large hydrocarbons into smaller ones and introduces unsaturation. When ethane is the feedstock, ethylene is the product.

    en.wikipedia.org/wiki/Oxidative_coupling_of_methane

    Ethylene derivatives are found in food packaging, eyeglasses, cars, medical devices, lubricants, engine coolants and liquid crystal displays. Ethylene production by steam cracking consumes large amounts of energy and uses oil and natural gas fractions such as naphtha and ethane. The oxidative coupling of methane to ethylene is written below: [1 ...
