| titleOfInvention | Method and system for pulp processing using cold caustic extraction with alkaline filtrate reuse |
| abstract | FIELD: chemistry. n SUBSTANCE: method for pulp processing using cold caustic extraction includes: delignifying organic materials in a digester and treating the resulting brown pulp to obtain semi-purified pulp for use in producing soluble pulp; extracting the semi-purified pulp with a caustic solution during a cold caustic extraction process; washing the purified pulp and collecting the obtained spent wash liquid by separating the hemicellulose-containing solution from the purified pulp; combining the spent wash liquid and the hemicellulose-containing solution to obtain an alkaline filtrate; concentrating the alkaline filtrate and using at least a portion of the concentrated alkaline filtrate in said digester to obtain a soluble pulp. n EFFECT: high content of alpha cellulose in soluble cellulose and high efficiency of using the filtrate. n 50 cl, 5 dwg, 1 tbl, 4 ex |
