POST-TREATMENT FOR POLYMER PELLETS

摘要

A continuous process for minimizing the agglomeration of freshly manufacture d polyolefin pellets comprising the steps of: - feeding an aqueous stream containing polyolefin pellets to a tower, - cooling said polyolefin pellets during their upward flow along said tower by means of a downward flow of a cooling agent having a density higher than said polyolefin, - collecting the cooled pellets from the top of said tower after a residence time in the towe r comprised between 2 and 20 minutes.
