巴西拥有几个世界级大型漂白化学木浆厂,为了降低漂白成本,工厂采用了Metso自动化技术,即连续、快速的在线分析仪表,及时获知过程中纸浆卡伯值、白度和残余化学品等的变化,为准确加入漂白化学品创造了条件。通过安装过程优化控制系统稳定产品质量,进一步降低化学品消耗。其经验值得借鉴。
Brazil has several world-class large-scale bleached chemical wood pulp mills. To reduce bleaching costs, the plant uses Metso automation technology, a continuous, rapid on-line analytical instrument with timely knowledge of pulp kappa number, whiteness and residual chemicals The changes created the conditions for accurate bleaching chemicals. Optimize the control system through the installation process to stabilize product quality and further reduce chemical consumption. Its experience is worth learning.
