Description:
Ethylene is one of the most important fundamental chemicals in petrochemical industry as it is the source material for a variety of products such as polyethylene resin, ethylene glycol, vinyl chloride resin, acetic acid, styrene, and alpha olefin, which are produced by polymerization, oxidation, alkylation, hydration, or the addition of halogen.The cracking of a single hydrocarbon (or a mixture of hydrocarbons) into vastly different compounds involves complex reaction kinetics, which is influenced by some variables. Commercially, only a few of these variables can be controlled through the design of the cracker furnace. The key parameters that have the most significant effect on the pyrolysis, or steam cracking, of hydrocarbons, are:
• Feedstock composition
• Steam to hydrocarbon ratio
• Residence time
• Hydrocarbon partial pressure
• Temperature profile and coil outlet temperature
Once the feedstock or feedstock slate has been selected, the cracker must be modelled and designed to determine the cracking severity/selectivity that produces the optimal profitability – in some cases, optimal flexibility to accommodate varying feedstock is also a key design consideration. Many key process parameters are determined by the physical process design and process unit sequencing available by each licensor of olefins technology.
