| titleOfInvention | Continuous method of manufacturing pulp from herbaceous plant material |
| abstract | FIELD: chemistry. n SUBSTANCE: method consists of the following stages: preparation of an herbaceous plant material by grinding, dust removal, continuous cooking, dispersion, dilution of pulp, sorting and fractionation, removal of black liquor concentration, dilution of fresh water, getting the finished pulp suitable for the manufacture of paper or sheets of cellulose, and, optionally, bleaching paper pulp. Continuous cooking takes place in a vertical column at a temperature of 70-100°C for 40 minutes to 2 hours; as a result, a cooking suspension of the following composition is formed (on average): a weight percentage of NaOH 0.9-1.5; a weight percentage of NaCl or Na 2 SO 3 0.15-0.4, and a weight percentage of herbaceous plant materials 15-18; where the concentration of ingredients is calculated from the weight of the liquid phase. The preferred herbaceous material for this method is miscanthus (Miscanthus x giganteus, Andersson). n EFFECT: after sorting and fractionation, two fractions are formed, one of which then passes the grinding process, and the other is processed into finished pulp with or without bleaching. n 9 cl, 1 tbl, 2 dwg |
