Managing Fiber Lines for Improved Output and Quality

大多数制浆企业的操作工艺与设备或工艺厂家提供的工艺都会出现很大偏离,甚至在工艺和原料相同的两条制浆线上产量与品质都相差较大。文章分析了产生这种现象的原因,介绍了制浆生产中提高生产管理水平,增加产量、改善产品品质的一些经验。

Over the period, most of the fiber lines have deviated significantly from the standard operating procedures provided by the equipment/technology suppliers for a given raw material. Our experience shows that the two fiber lines are most likely to have different pulp output and quality even if they operate with more or less similar technology and chip furnish. This could be due to many reasons such as operating practices and the use of specialty chemicals to enhance productivity and quality. Though most of the fiber lines aim to maximize their profit but the vital question is as to how to minimize these variations. While working with different fiber lines, our strategy is to interact closely with the operating management to optimize pulping process while running applications such as digester additive, pitch control, and DCM extrac- tive, brown stock washing and scale control applications to improve pulp quality and output. With a thorough understanding of the wood science and chemistry, and that of the pulping technology used, these efforts are clubbed with the innovative use of the aforesaid applications. Additionally with continuous focus on introducing new technologies to the fibers lines such as partial auto-causticizing technology, we not only provide an impetus to mill＇s ongoing efforts for an improved environmental management but also help to reduce the production cost. Overall our BEST PRACTICES are aimed to provide continuous improvement to the fiber lines to achieve their bottom lines on a sustainable basis.
