  • Paraffin isomerization process comprising fractionation having at least two draw-off levels associated with at least two isomerization zones
    Patent number: 5994607
    Abstract: The invention concerns a process for isomerising a feed containing essentially hydrocarbons, preferably paraffins containing principally 4 to 8, preferably princiapply to 6 and more principally 5 and/or 6 carbon atoms per molecule, comprising a fractionation zone and at least two isomersation reaction zones, said process comprising carrying out the following steps:(1) sending the feed to a fractionation zone;(2) drawing off at least a portion of the liquid circulating in said zone, via at least two draw-off levels; and(3) sending the major portion of the liquid drawn off in step (2) to at least two isomerisation zones, each isomerisation zone being associated with a draw-off level.
