Web2.2 Cracking furnaces. Cracking furnaces are used in the production of olefins such as ethylene which is an important high-volume building block for many types of materials such as plastics, resins, and fibers [12]. Thermal cracking in a furnace, commonly referred to as a cracking furnace, is one of the most common methods to produce ethylene. WebKeywords: Steam cracking, Ethane, Propane, Naphtha, Kinetics, Feed characterisation 1.Introduction The steam cracking process is a cornerstone of the chemical industry as it generates highly valu-able olefins – from which ethylene, propylene and butadiene are the most relevant ones – from lower value feedstocks.
