The challenge of black liquor flow

Within pulp mills, black liquor flow measurement has long been a source of uncertainty. While flow values may be available, their accuracy is often questionable. This lack of precision creates significant risks, as mills rely on this data to manage digester liquor balance and maintain stability across the liquor cycle. When inaccurate information drives operations, hydraulic loads to evaporation and recovery are affected, leading to inefficiencies and economic losses.

Another persistent issue is the silo effect between individual operating units. When departments operate in isolation, bottlenecks emerge, dead load accumulates, and overall performance declines. Without a unified view of liquor balance, mills struggle to identify root causes and optimize processes.

The 3G Acoustic PROSONIC Instrument

The non-invasive 3G Acoustic PROSONIC addresses these challenges by providing accurate, real-time visibility into liquor flows. Designed for permanent installation yet adaptable for temporary monitoring, the system can be installed in just one hour and connected directly to the mill DCS. Once operational, PROSONIC delivers precise flow data that supports root cause analysis and KPI tracking from cooking through evaporation.

By eliminating uncertainty in flow measurement, mills gain the ability to make informed decisions, reduce bottlenecks, and improve overall efficiency. The technology empowers operators across departments, breaking down silos and creating a shared understanding of liquor balance.

Proven results in kraft mills worldwide

The 3G Acoustic PROSONIC has already been proven in Kraft mills around the world. Its ability to deliver reliable flow measurement has redefined liquor balance management, enabling mills to achieve measurable improvements in efficiency, reliability, and economic performance.

For mills seeking to strengthen their operations, PROSONIC offers a practical and effective solution. Detailed insights are available through our white paper and tutorial video on installation procedures. With a track record of success and a commitment to supporting mills globally, we stand ready to help facilities achieve operational excellence.
