Abstract

"MONITORAçãO E CONTROLE DE POLIMERIZAçãO USANDO INDICADORES GUIA". A presente invenção refere-se a métodos de monitoração e controle de reações de polimerização. A razão das concentrações de dois componentes do reator são determinadas em uma corrente gasosa de um reator para se obter uma função indicadora guia L. O valor de L ou de uma função de L, como um valor reescalado ou um inverso, é comparado com um valor alvo, e pelo menos um parâmetro de reator é ajustado em resposta a um desvio entre L ou a função de L e o valor alvo. A monitoração do indicador guia permite diagnose rápida de problemas do reator, e ajustes rápidos de parâmetros de reator, comparados à análise de laboratório de amostras de propriedades de polímero.
