Smart Lime Mud Dry Solids Analyzer is a fully automated NIR-based measurement system that continuously monitors lime mud dry solids content after the lime mud filter. Accurate dry solids data supports optimization of lime kiln feed quality and recausticizing process performance.
The Challenge
Lime mud dry solids content is a critical quality parameter for the lime kiln feed in kraft pulp mill recausticizing. Low dry solids content increases the moisture load in the kiln, raising fuel consumption and reducing production capacity. Inconsistent dry solids cause variable kiln operating conditions, complicating temperature control and increasing the risk of operating upsets. Manual sampling and laboratory analysis provide only infrequent snapshots of lime mud filter performance, limiting operators' ability to maintain consistent kiln feed quality.
The ANDRITZ Solution
Smart Lime Mud Dry Solids Analyzer is a fully automated measurement system that continuously monitors lime mud dry solids content at the outlet of the lime mud filter. Using near-infrared (NIR) spectroscopy, it delivers real-time dry solids measurements without manual sampling or laboratory preparation — providing the continuous data needed to optimize lime mud filter performance and ensure consistent kiln feed quality.
How It Works
The NIR analyzer measures lime mud dry solids content by analyzing light absorption characteristics of the lime mud sample at the filter outlet. The measurement is fully automated — no operator intervention is required for routine operation. Continuous dry solids data enables operators to monitor lime mud filter performance in real time, detect deviations in filter cake quality, and adjust filter operating parameters or kiln feed to maintain target dry solids levels. Data is available for DCS integration to support automated process control.
Key Benefits
- Continuous automated dry solids monitoring at the lime mud filter outlet
- Early detection of filter performance deviations before kiln feed quality is affected
- Reduces kiln fuel consumption variability by ensuring consistent feed dry solids
- Eliminates periodic manual sampling for dry solids quality control
- Supports process optimization across the full lime mud filter and kiln feed system
