Abstract
Procedimiento y dispositivo para eliminar componente volátiles de sustancias plásticas, pudiendo ser estar una fusión, solución o dispersión de plástico, introduciendo la fusión, solución o dispersión de plástico en una extrusionadora de desgasificación de disposición horizontal bajo una presión que corresponde como mínimo, a la presión de saturación de los componentes volátiles a estas temperaturas, calentando la carga y transportándola bajo evaporación de los componentes volátiles y comprimiendo la mezcla, caracterizándose el procedimiento porque la fusión solución o dispersión de plástico se alimenta desde abajo en la extrusionadora de desgasificación y se evaporan los componentes volátiles inmediatamente después de entrar el plástico en la extrusionadora, abandonando la cantidad principal de los componentes volátiles la extrusionadora por una abertura que se encuentra colocada perpendicularmente encima de lugar de alimentación de los materiales plásticos.
