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. WebEthylene production from ethane is far superior in terms of cost to production from naphtha, which is a conventional feedstock for ethylene production by the steam cracking.

WebThermal cracking of paraffinic hydrocarbons in presence of steam is a widely used process for making Ethylene. A variety of feed-stocks ranging from light gases like ethane, propane and butane to liquids like naphtha and Natural Gas Liquid (NGL) are commonly used. Ethylene and other products are formed in the cracking furnace itself; Modern high-pressure thermal cracking operates at absolute pressures of about 7,000 kPa. An overall process of disproportionation can be observed, where "light", hydrogen-rich products are formed at the expense of heavier molecules which condense and are depleted of hydrogen. The actual reaction is known as homolytic fission and produces alkenes, which are the basis for the economical… migraine phenotype
