Abstract
A method for the removal of polymer from a straight-chain paraffin purge medium used in a monoolefin adsorption-desorption separation process comprising recycling a countercurrent purge step polymer containing straight-chain paraffin product for use as purge medium in the process without separation of polymer from the straight-chain paraffin and separating polymer from at least a portion of an adsorption step and a copurge step polymer containing straight-chain paraffin product and recycling the purified straight-chain paraffin for use as purge medium in the process.
