| titleOfInvention | Method and apparatus for pulp yield enhancement |
| abstract | The process of the present invention purposefullynprecipitates a portion of the dissolved lignin ontonpulp fibers to improve pulp yield of unbleached pulp.nThe resulting retention of lignin on the pulp createsnan increase in pulp yield. Washing the pulp in anseries of washer stages sequentially removes entrainednlignin. Between each of the washer stages, addingndilution water repulps a pulp mat that exits from anprior washer stage and creates a pulp stream for a nextnwasher stage. After at least one of the washer stages,nadding an acidifying agent to the pulp stream forms anpulp product by precipitating the entrained lignin ontoncellulosic fibers contained in the pulp stream.nFinally, the process removes the pulp product from thenseries of washer stages with the pulp product having atnleast about a 1 unit increase in Kappa number. |
