PapermakingPaper Quality & Energy Optimization
Stabilizing basis weight and moisture in pulping and drying processes while reducing dryer energy consumption — achieving dual improvements in quality and energy efficiency.
Industry Pain Points
Basis Weight Control Difficulty
Basis weight is affected by pulp consistency, machine speed, and wire section dewatering — high variance and poor stability.
High Drying Energy Consumption
Dryer section steam accounts for over 60% of total papermaking energy — lacking fine-grained steam distribution control.
Pulping Quality Variance
Fiber characteristics change with raw material batches — freeness is hard to precisely control, affecting paper strength and uniformity.
Multi-process Coupling
Pulping, forming, and drying processes are interconnected — single-process optimization cannot achieve full-line optimum.
Moisture Control Difficulty
Paper moisture is influenced by multiple environmental and process factors — too high or too low affects quality and downstream processing.
Experience-based Operation Limitations
Key parameter adjustments rely on operator judgment — shift changes and personnel turnover create quality variance risk.
