Abstract
PROCEDIMIENTO PARA EL FRACCIONAMIENTO DE UNA CORRIENTE DE EFLUENTE DE REACTOR DE METIL-BUTIL ETER TERCIARIO, QUE CONTIENE METANOL, ISOBUTANO, BUTANO NORMAL Y BUTENOS DE CADENA RECTA. CONSISTE EN FRACCIONAR LA CORRIENTE DE EFLUENTE, MEZCLADA CON BUTENOS DE CADENA RECTA AÑADIDOS; TOMAR EL METANOL EN LA PARTE SUPERIOR DEL REACTOR EN FORMA DE VAPOR, QUE CONTIENE TAMBIEN ISOBUTILENO SIN REACCIONAR, BUTILENOS DE CADENA RECTA, BUTANO O ISOBUTANO; CONDENSAR Y SOMETER EL LIQUIDO OBTENIDO A ADSORCION SOBRE ALUMINA ACTIVADA PARA ABSORBER EL METANOL. EL METIL-BUTIL ETER TERCIARIO SE TOMA DEL FONDO DEL REACTOR. EL METIL-BUTIL ETER TERCIARIO TIENE APLICACIONES COMO ADITIVO DE LAS GASOLINAS PARA ELEVAR SU INDICE DE OCTANO.
