Benzene removal from FCC naphtha |
摘要 |
An integrated process for the isolation of benzene contained within a fluid catalytically cracked naphtha is disclosed wherein a C6 fraction containing a benzene concentrate is subjected to etherification with alcohol (e.g. methanol and/or ethanol) to convert the C6 isoolefins to ethers which are separated by fractional distillation. If desired the ethers may be dissociated to the isoolefins and alcohol. The remaining material in the benzene concentrate may then be treated to remove olefins and organic sulfur compounds so that the benzene may be removed by solvent extraction. Alternatively the benzene in the remaining material may be subjected to hydrogenation.
