Abstract

resumo patente de invenção: "processo de desgaseificação e tamponamento de partículas poliolefínicas obtidas por polimerização de olefinas". processo de polimerização de poliolefina compreendendo: (a) formação de polímero particulado de poliolefina por de polimerização de olefinas na presença de catalisador de polimerização em reator de polimerização; (b) descarga das partículas poliolefínicas formadas do reator; (c) desgaseificação das partículas por processo que compreende etapa final de exposição de partículas poliolefínicas a fluxo de nitrogênio em recipiente desgaseificado; e (d) transferência das partículas poliolefínicas de um recipiente no qual as partículas são postas em contato com fluxo de nitrogênio para um dispositivo de mistura de produtos fundidos no qual as partículas poliolefínicas são fundidas, misturadas e posteriormente peletizadas sem que as partículas passem por um dispositivo de tamponamento, em que o processo é caracterizado por compreender um recipiente de desgaseificação preenchido parcialmente com as partículas e pelo fato de o volume vazio no interior do recipiente de desgaseificação ser suficiente para receber mais partículas por pelo menos três horas se a transferência de partículas poliolefínicas da etapa d) do recipiente de desgaseificação para o dispositivo de mistura de produtos fundidos for interrompida e a transferência de partículas poliolefínicas do reator de polimerização de acordo com a etapa b) for mantida a uma taxa inalterada.
