Abstract

"APARELHO PARA DETECTAR A TRANSMISSãO DE TAMPõES DE CATALISADOR ATRAVéS DE UM CONDUTO, MéTODO PARA DETERMINAR A MASSA DE MATERIAL TRANSMITIDO ATRAVéS DE UM CONDUTO, E, SISTEMA PARA DETERMINAR A MASSA DE MATERIAL TRANSMITIDO ATRAVéS DE UM TUBO". A invenção refere-se a um aparelho (10) para detectar a transmissão de tampões de catalisador através de um conduto (105) conduzindo a um reator de polimerização, compreendendo uma fonte de radiação óptica (9) localizada fora do conduto através do qual passa um feixe de luz (9a) ao longo de um trajeto de luz e um detector de radiação óptica disposto para detectar o feixe de luz. Quando um tampão de catalisador passa através do conduto, ele bloqueia o trajeto de luz e, assim, a intensidade de luz registrada pelo detector cai. Desta maneira, tampões de catalisador podem ser detectados. O aparelho também pode ser usado para medir a massa de um objeto que passa através de um conduto por detectar repetidamente a velocidade do material e a intensidade de luz, multiplicar os valores de velocidade e intensidade para obter uma curva de resultado e integrar esta curva a fim de obter um valor indicativo da massa do material.
