A method for processing pentanes obtained from a DIB unit is disclosed. The process can include separating a first stream containing pentanes obtained from a DIB unit, in a separation column to obtain a second stream comprising iso-pentane and a third stream comprising n-pentane and neo-pentane; and subjecting the third stream to a butane isomerization unit producing a fourth stream containing iso-pentane, n-pentane, and neo-pentane.
