Approach System & Headbox
The approach flow and headbox are critical to paper machine productivity, product quality, and process stability. Variations in operating conditions directly affect product quality, grade change transition times, and off-spec paper production, ultimately impacting overall machine performance.
Enero Solutions’ Advanced Process Control (APC) solutions optimize the approach flow and headbox by:
- Stabilizing critical wet-end control loops
- Fine-tuning basis weight and consistency control loops
- Implementing precision control of pH and chemical dosing
These results are achieved through a comprehensive approach that includes:
- Auditing and tuning final control elements, including valves and instrumentation
- Identifying optimization opportunities and developing robust control strategies
This approach improves operating stability, maximizes productivity, and reduces off-spec paper production. Direct integration into the DCS ensures reliable and sustainable implementation.
APC becomes a strategic lever for transforming the approach system and headbox into a more stable, efficient, and productive process
Dryer Section
The dryer section is critical to final sheet quality, production stability, and overall mill energy performance. Optimizing dryer can temperature profiles, evaporation rates across each section, and steam and condensate distribution helps achieve target sheet moisture with minimal energy consumption while maintaining process stability.
Enero’s APC solutions, integrated directly into your DCS, help:
- Stabilize temperatures and sheet moisture to reduce variability
- Optimize temperature profiles and steam and condensate flow to improve energy efficiency
- Integrate process constraints into the control strategy to unlock dryer section capacity
This approach improves overall performance, maintains consistent sheet quality, and reduces steam, natural gas, or biomass consumption, contributing directly to process decarbonization.

Stock Preparation
Stock preparation is at the heart of wet-end operations and plays a critical role in the stability, quality, and productivity of the entire paper machine. Controlling key process parameters —including consistency, pH, levels, and chemicals flow— is essential to reducing variability, minimizing off-spec production, and maintaining reliable operations.
Enero’s APC solutions, integrated directly into your DCS, help:
- Stabilize critical control loops to reduce stock variability
- Optimize levels, consistency, and pH to maintain consistent quality
- Improve productivity while maintaining reliable operations
- Maximize energy efficiency and reduce losses
This approach transforms stock preparation into a more stable, efficient, and energy-efficient process.

Bleaching
Pulp bleaching is a critical process that directly impacts the brightness, visual quality and cleanliness of the final sheet. An unstable bleaching process can lead to increased variability, excessive chemical consumption, and operating constraints.
Enero’s APC solutions, integrated directly into your DCS, help:
- Optimize chemical consumption by reducing the usage of key bleaching agent such as ClO₂ and NaOH.
- Stabilize the process to maintain consistent pulp quality
- Improve operating flexibility and overall productivity
This approach turns bleaching into a reliable, efficient, and cost-effective process capable of meeting the stringent requirements of the pulp and paper industry.
