ABSTRACT:
An aromatics complex flow scheme has been developed. C7-C8aliphatic hydrocarbons are recycled to an isomerization unit of a xylene recovery zone to increase the efficiency of the isomerization unit. This improvement results in an aromatics complex with savings on capital and utility costs and an improvement on the return on investment.
