Valmet analyzers help Luzhou Yongfeng achieve breakthroughs in quality and profitability with full investment payback in one year
Valmet recently announced that the online pulp process analysis solution supplied to Luzhou Yongfeng Pulp Co., Ltd. (“Luzhou Yongfeng”) has achieved outstanding results. The contract was signed at the end of 2022 and includes one Valmet Fiberline Analyzer. Since startup in 2023, the equipment has operated reliably, helping Luzhou Yongfeng significantly reduce brightness variations in the final pulp and greatly improve product quality. Notably, with remarkable cost reduction and efficiency improvement, Luzhou Yongfeng achieved full return on investment within one year after commissioning, becoming a benchmark of intelligent investment for pulp enterprises.
Record-breaking brightness stability and exceeding economic expectations
The multi-analyzer platform for all key fiberline measurements covering cooking and bleaching, has brought revolutionary production improvements to Luzhou Yongfeng. After one year of operation, performance data fully demonstrates the solution’s exceptional value:
Leap forward in brightness stability
Supported by precise cooking control and stable bleaching inlet conditions, brightness variation of the final pulp has been drastically narrowed. According to customer data, the standard deviation of brightness has been reduced by more than 50% compared with before commissioning. This allows Luzhou Yongfeng to consistently deliver highly uniform pulp to downstream customers, significantly enhancing market competitiveness.
Substantial reduction in chemical consumption and production costs
Accurate control of bleaching chemical dosage avoids overconsumption, reducing total chemical consumption per ton of pulp by approximately 8%. Meanwhile, stable pulp quality reduces downgrading and rework losses caused by brightness fluctuations, steadily improving line operating efficiency.
Full investment payback within one year
Combined benefits from chemical savings, reduced quality losses, and increased output enabled Luzhou Yongfeng to recover the entire investment — including equipment, installation and services — in only one year after commissioning. This investment payback speed was marked as a benchmark in the industry.
Since we started using the Valmet Fiberline Analyzer, we have gained a much more comprehensive overview of the entire pulping process.
Previously, we relied on experience and waited for lab results, which always caused delays. Now data updates in real time, so we can detect and correct issues immediately. This has not only improved our pulp quality but also cut costs. Unexpectedly, we recovered the equipment cost in just one year! This investment is worthwhile.
Empowering customers with advanced measurements for operational excellence
“We are honored to help Luzhou Yongfeng achieve higher quality and efficiency and realize investment payback in such a short time through advanced online analysis technology,” said Li Bin, Automation Business Line, Valmet. “This successful case confirms that real‑time, accurate measurement of key pulping parameters is essential for improving quality, lowering costs and accelerating return on investment. Valmet offers online analyzers for the entire pulping process and profound process expertise. We will continue partnering with Chinese customers to turn data into tangible productivity and move toward a smarter and more sustainable future.”
Valmet remains committed to delivering innovative technologies and solutions to the pulp and paper industry, helping customers optimize processes, improve efficiency and achieve high‑quality, sustainable development.
