Abstract

"PóS-TRATAMENTO PARA PéLETES POLIMéRICOS". O invento descreve um processo contínuo para minimizar a aglomeração de péletes poliolefínicos recém produzidos compreendendo as etapas de: - alimentar uma corrente aquosa contendo péletes poliolefínicos a uma torre, - resfriar ditos péletes poliolefínicos durante seu fluxo ascendente ao longo de dita torre por meio de um fluxo descendente de um agente refrigerante tendo uma densidade maior que dita poliolefina, - coletar os péletes resfriados a partir do topo de dita torre após um tempo de residência na torre compreendido entre 2 e 20 minutos.
