Abstract

"PROCESSO PARA RESFRIAR PELOTAS DE TEREFTALATO DE POLIETILENO". Economias de energia são realizadas durante a produção comercial de tereftalato de polietileno por resfriamento parcial de pelotas de tereftalato de polietileno que saem de um reator de estado sólido por contato com água, e usando o calor residual armazenado nas pelotas para vaporizar água associada para formar as pelotas secas.
