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.
The products produced in the reaction depend on the composition of the feed, the hydrocarbon-to-steam ratio, and on the cracking temperature and furnace residence time. Light hydrocarbon feeds such as ethane, LPGs or light naphtha give product streams rich in the lighter alkenes, including ethylene, propylene, and butadiene.
A Millisecond Furnace is a device used for cracking naphtha into ethylene, [1] by extremely short (50 to 100 millisecond) exposure to temperatures of about 900 degrees Celsius, followed by a rapid quenching below 750 degrees Celsius. It was developed by M. W. Kellogg and Idemitsu in the 1970s. [2]
In March, 2011, Wison Engineering, a subsidiary of Wison Group, finished construction on the world's largest single production capacity of an ethylene cracking furnace. [15] The plant, with a production capacity is up to 192,000 tons/year, was handed over to BASF-YPC. The old record of 150,000 tons/year was also held by a cracking plant that ...

Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2. It is a colourless, flammable gas with a faint "sweet and musky" odour ...
The Shell Pennsylvania Petrochemicals Complex, [2] [3] [4] formally known as Shell Polymers Monaca, is an ethylene cracker plant located in Potter Township, Pennsylvania, United States, owned and operated by Shell Oil Company, the American subsidiary of supermajor oil company Royal Dutch Shell. [5]
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
