Abstract
"PROCESSO DE CONTROLE E DE MONITORAçãO EM LINHA DA CONVERSãO DE MONÈMERO EM POLIMERIZAçãO EM EMULSãO DENTRO DE UM REATOR". A invenção refere-se a um processo de controle e de monitoração em linha da conversão de monómero durante polimerização em emulsão. De acordo com o citado processo, começando de um ponto de inicialização no tempo, é continuamente realizado um balanço da quantidade de calor alimentado Q~ IN~ a uma reação, da entalpia de reação Q~ RE~ adicionada pelo fornecimento de monómeros e da quantidade de calor dissipado Q~ OUT~do reator. Uma quantidade de calor não-dissipado Q~ AD~é calculada baseando-se nestes valores que no caso de uma reação adiabática espontânea resultará em um aumento na temperatura interna e na pressão interna do reator. Uma checagem é conduzida se as potenciais pressões e temperaturas adiabáticas sempre estiverem dentro de limites superiores predeterminados. Se os citados limites superiores forem ultrapassados, a adição de monómeros no reator é diminuída ou interrompida.
