Definition - What does Pyrolysis Coil mean?
A pyrolysis coil is a mechanical component of a cracker furnace where highly endothermic reactions occur to convert hydrocarbons to petrochemicals.
Corrosionpedia explains Pyrolysis Coil
A pyrolysis coil houses inlet steam and hydrocarbons at reduced partial pressures. Due to the endothermic nature of the conversion reactions, heat typically in excess of 700 °C (1292 °F) is introduced into the coils. Pyrolysis coils are used in the generation of propylene and ethylene as end products.
