Abstract

Método de descarga de um polímero a partir de um reator de polimerização. O presente invento descreve um método de descarga de um polímero a partir de um reator de polimerização operado continuamente, em que pelo menos um monómero é polimerizado para formar partículas de polímero, o método compreendendo ajustar a taxa de descarga das partículas de polímero por meio de uma válvula pistão tendo um elemento pistão conectado a um atuador, dito atuador sendo capaz de modular o cursa do pistão dentro da dita válvula pistão.
