The benzene feedstock should leave the alkylation reactor for at least six volumes of recycle
Why do I feel that this sentence seems incomplete, or the Alkylation Reactor is placed here to be superfluous to my understanding left=kept This post was last edited by I Love Rainy Days on 2009-2-25 15:18 ]

be left circulating =be kept circulating can be understood as "keep"
