Energy, Recovery,  Lime Kiln and Recaust Track

This track is organized by the Energy, Recovery and Recaust Main Committee (ERR)

This Committee provides a forum to collect information and disseminate the information as a guideline for energy management, sharing ideas on conserving energy, and/or increasing efficiency. The Committee publishes TIPs for public review (e.g. TIP 0416-24) and focuses on Pulp and Paper mills and power plants in areas of energy management and energy consumption including electrical, steam, condensate and efficient heat exchange.

Attendees are invited to participate in the Energy, Recovery and Recaust Committee Meeting to learn
more about their activities and how to get involved.


The Energy, Recovery, and Recaust (ERR) Committee meeting will be held on:
Monday, October 28th from 1:30pm - 3:00pm

 ERR Subcommittees will meet on:  Monday, October 28th from 3:30pm - 5:00pm

  • Lime Kilns & Recaust
  • Energy
  • Recovery & Power Boilers
  • Water Treatment


Track Purpose:

The chemical recovery cycle makes kraft pulping economically feasible. Key unit operations including the recovery boiler, recaust plant, lime kiln and power generation have significant impacts on maintaining high mill production rates. The purpose of this year’s sessions and panels are to provide experiences from industrial and academic experts on reducing variability, debottlenecking, optimization strategies and new equipment designs

Why Should You Attend?

This track will provide participants with both fundamental and practical knowledge on key process areas in a mill, including evaporators, recovery boiler, recaust plant, lime kiln and energy generation. Topics also include utilizing bio-fuels and minimizing emissions. Participants can also attend panels for in depth discussions with industry experts.

Who Should Attend?
  • Recovery and Recaust Operators

  • Lime Kiln Operators

  • Process Engineers

  • Control Engineers

  • Technical Superintendents/Managers

  • Graduate Students

Learning Outcomes for Attendees:

1.    Gain fundamental and practical knowledge for key unit operations in the recovery cycle.
2.    Apply learning at participants’ mill site to gain improvements in process operability, reduce variability, minimize downtime and improve safety.

Demonstration of Learning Outcomes:

1.    Increased understanding of green liquor processing such as recognizing how to avoid smelt-water explosion, reduce scale formation and improve clarification.
2.    Increased understanding of black liquor evaporator process including reproducing strategies to reduce steam usage, reduce evaporator fouling and improve soap separation.
3.    Gain knowledge in recovery boiler design and apply operational best practices.
4.    Increased knowledge on modeling technique and control strategies that can be applied to recovery boilers, evaporators and dissolving tanks.
5.    Increased knowledge in lime kiln operation, design and maintenance to optimize day to day operation and troubleshoot common issues such as ringing.
6.    Gain knowledge in auxiliary equipment in the recovery cycle and learn basic troubleshooting techniques.
