Abstract

604002 Disclosed herein is a method for pulp manufacturing using cold caustic extraction for production of dissolving pulp and the use of the method in a kraft process, comprising: - delignifying organic materials in one or more digesters and treating a resulting brown stock to yield semi-purified pulp for use In the production of dissolving pulp; - extracting the semi-purified pulp with a caustic solution during a cold caustic extraction process to yield a purified pulp and a solution containing hemicellulose; - washing the purified pulp and collecting a spent washing liquid therefrom while separating the hemicellulose-containing solution from the purified pulp; - combining the spent washing liquid and the hemicellulose-containing solution to form an alkaline filtrate; - concentrating the alkaline filtrate to form a concentrated alkaline filtrate without purifying the hemicellulose-containing solution or alkaline filtrate to substantially remove the hemicellulose therein; and - utilizing at least a portion of the concentrated alkaline filtrate in said digester in connection with production of dissolving pulp.
