WebPEP Report 29J. Published December 2015. In January 2014, ExxonMobil officially opened in Singapore a novel steam cracker that produces olefins directly from crude oil. The Saudi Arabian Oil Company (Aramco) has discussed plans to build a crude-to-olefins complex. SABIC is another company that has looked into direct crude-to-olefins. In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature a…
