Abstract
"MéTODO E APARELHO PARA FABRICAçãO DE ESTIRENO ATRAVéS DA DESIDROGENIZAçãO DE ETIL BENZENO NA PRESENçA DE VAPOR A ALTAS TEMPERATURAS E MéTODO PARA A DESIDROGENIZAçãO DE UM COMPOSTO DE ALQUILA AROMáTICA NA PRESENçA DE VALOR A ALTAS TEMPERATURAS". Trata-se de métodos e aparelhos correspondentes aperfeiçoados para recuperar eficientemente o calor da condensação do vapor da parte superior produzido durante a separação de vários componentes do efluente da reação de desidrogenação, particularmente em operações de transformação de etil benzeno em estireno através do uso de pelo menos um compressor para facilitar a vaporização azeotrópica de uma mistura de etil benzeno e água dentro de uma faixa preferida de condições de pressão/temperatura para minimizar as reações de polimerização indesejadas.
