介绍了将硫酸盐浆生产工艺改造为溶解浆生产工艺的最佳策略。在溶解浆生产过程中,半纤维素水解和后续的抽提会影响生产过程的能量平衡和化学平衡,采用计算机模拟生产过程和夹点分析方法讨论了抽提半纤维素过程对能量平衡和操作条件的影响。此外,还找出了提高溶解浆产能的瓶颈,并提出了新工艺条件下降低能耗的措施。
The best strategy to transform kraft pulp production process into dissolving pulp production process is introduced. In the process of dissolving pulp production, hemicellulose hydrolysis and subsequent extraction will affect the energy balance and chemical balance in the production process. The process of extraction of hemicellulose and energy balance and operation are discussed by computer simulation of production process and pinch point analysis Conditions of influence. In addition, the bottleneck to improve the productivity of dissolving pulp was also found, and measures to reduce energy consumption under new process conditions were put forward.
