Abstract
METODO DE SEPARACION DE CAFEINA DE CARBON ACTIVO. CONSISTE EN LA DESORCION DE CAFEINA MEDIANTE UNA CORRIENTE DE GAS INERTE TAL COMO DIOXIDO DE CARBONO, NITROGENO O SUS MEZCLAS, QUE SE CIRCULA A UNA TEMPERATURA COMPRENDIDA ENTRE 350JC Y 450JC, PERPENDICULARMENTE A TRAVES DE UNA CORRIENTE DE CARBON ACTIVO QUE SE HALLA CARGADO CON CAFEINA; SEGUIDA DEL ENFRIAMIENTO RAPIDO DE DICHA CORRIENTE DE GAS CON AGUA, PRECIPITACION DE LA CAFEINA Y SEPARACION DE LA MISMA.
