Abstract
Un proceso para recuperar solidos de éter de celulosa salables en una pasta acuosa a partir de un reactor en donde se producen los solidos de éter de celulosa, o en una pasta acuosa a partir de un centrífugo o filtro en donde se ha removido una porcion de los solidos de éter de celulosa a partir del reactor, el cual comprende hacer fluir la pasta hacia un ciclon hidráulico a a una temperatura mayor que el punto de gelificacion de los solidos de éter de celulosa en la pasta, y bajo condiciones que se hacen a la medida para los solidos de éter de celulosa particulares de la pasta, y para el proceso mediante el cual se han hecho los mismos.
