Definitions
- Operation in accordance with the invention also yields economics in construction and maintenance of the pyrolysis heater.
- a conventional heater may require a 675 foot process coil
- a heater for use with the present invention may require only a 200 foot coil, as a result of higher heat flux and shorter residence times involved.
- propylene will also be formed during pyrolysis, whereas substantially little is formed during the pyrolysis of ethane to produce ethylene.
- the term is also to be interpreted as including a mixture of hydrocarbons, such as ethane and propane wherein propylene is included in the reactor efiiuent where such mixture is pyrolyzed under conditions to produce ethylene.
