Essay --

In recent years, light olefins atomic number 18 used as building blocks for a large variety of chemicals and petrochemicals harvest-feasts that are produced from crude oil. flow olefins are in a class of hydrocarbons with a single restate bond and a chemical formula of CnH2n. Ethylene and Propylene are the intimately important olefins which form the backbone of the petrochemicals market. However, ethene and propylene take away no end use. The highly reactive double bond of the ethylene and propylene makes the molecule ideal for conversion to many useful return such as polymers (eg. polypropylene, polyethylene and polyvinyl chloride), synthetic rubber and fuel components. Currently, most olefins are produced via thermal cracking of naphtha or other light fractions of oil colour with steam, which is often referred to as steam cracking. During the process, the hydrocarbon feedstock which usually of fossil origin, is cracked into littler molecules. The process is innovative olefi n technologies in terms of energy efficiency. The resulting product mix from the cracking process which varies depending on the process c...
