Abstract

"PROCESSOS PARA PREPARAR POLìMEROS E PARA REDUZIR EMISSõES DE VOC DURANTE UM PROCESSO DE POLIMERIZAçãO" é apresentado um processo para a preparação de polímeros. O processo utiliza o deslocamento de ar em um reator de polimerização com vapor de água, um sistema fechado, e, uma bomba em alta pressão de operação para bombear o polímero através de um trocador em um circuito fechado externo, resultando em emissões reduzidas de compostos orgânicos voláteis.
