Abstract

"DISPOSITIVO PARA ALIMENTAçãO INICIADORA EM REATORES". A invenção refere-se a um processo para a produção de polietileno em reatores tubulares com ou sem autoclaves, no qual é alimentado um iniciador em cadeia radical a um meio fluido corrente que contém etileno mais comonómero, com ou sem etileno frio. Está sendo produzida uma torção entre duas correntes (61, 62) a serem misturadas a um ângulo (66) e pela provisão de um elemento de torção (20, 80) na seção transversal de circulação (27, 28). Na área de um local de alimentação (72, 81) para um iniciador em cadeia radical é configurado um estreitamento de seção transversal (63, 67, 71) no qual o iniciador em cadeia radical é introduzido através de uma abertura de saída otimizada (44), disposta fora do centro, de um dedo de alimentação (40) na corrente com torção (61, 62, 70).
