Abstract

"PROCESSO DE SEPARAçãO TéRMICA PARA A REMOçãO DE PELO MENOS UMA CORRENTE CONTENDO MONÈMEROS (MET)ACRìLICOS ENRIQUECIDOS". A invenção diz respeito a um método para a separação de um fluxo de massa contendo monómeros (met)acrílicos enriquecidos de uma mistura contendo monómeros (met)acrílicos, em que as fases líquidas com temperatura alta e teor de monómero (met)acrílico alto retidas na área de separação são minimizadas.
