Benzene Recovery from Refinery Sources by Co-production of Olefins

Description:

For decades benzene at a purity level of 99.9 wt% has been used in the petrochemical industry. This high purity was achieved by aromatic extraction. Improvements in alkylation technology and new data on cyclohexane oxidative processing suggest lower purity benzene can find its way to 90% of the market place, particularly for manufacturing styrene monomer, cumene, cyclohexane, linear alkylated benzene and derivatives, at a benzene cost savings of approximately 30%.
