| Abstract:Combined with engineering examples， the engineering overview of the production line of bleached kraft wood pulp and dissolving pulp through the convertion of the existing bleached kraft wood pulp production line was introduced in this paper. The material replacement of existing equipment， the addition of pre-hydrolysis system， the convertion of steam system， water system， chemicals and other systems were expounded， and the influence of alkali recovery system was introduced. It was shown that it was feasible to converted traditional kraft pulping into dissolved pulp. After the convertion， enterprises could switch pulp types according to market conditions to achieve maximum profit. |
