Ethylene milestones1913: Standard Oil’s scientist patented thermal crackingprocess1930ties: Ethylene was first separated from coke ovengas and the first commercial plant for the production ofethylene was built by Linde at that time1941: Standard Jersey (ExxonMobil’s predecessor)developed the world’s first steam cracker at Baton Rouge1950ties: Ethylene emerged as a large-volumeintermediate, replacing acetylene as prime material forsynthesisToday ethylene is primarily produced by thermal crackingof hydrocarbons in the presence of steam. Plantcapacities are up to 1-1,5 million t/yr ethylene.Other processes are also available or under development11Olefin production by processes, 200812010080million t6040200ethylenepropylenesteam cracking refinery operation others12
