Abstract
A process is presented for the removal of aromatics from an olefin stream. The process includes washing the olefin stream with a hydrocarbon stream to absorb aromatics generated in a dehydrogenation process. The olefin stream is compressed, then washed and cooled with a liquid hydrocarbon stream. The cooled and washed stream is passed to a separation drum to remove the liquid hydrocarbon stream containing the aromatics.
