Energy, Recovery, Lime Kiln and Recaust (ERLR)

 

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 equipment maintenance, process chemistry and new technologies.

The ERLR 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 are focused on maximizing the efficiency and throughput of the recovery cycle. Participants can also attend panels for in depth discussions with industry experts.

Learning outcomes: After successfully completing the sessions in this track, participants will be able to go back to their workplace and:

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

Demonstration of learning outcomes: After attending the ERLR presentation sessions attendees will have a better understanding of how to implement:

• Gain familiarity with online analyzers to improve recovery boiler operation by measuring black liquor properties while also assessing combustion byproducts.
• Better understanding of equipment associated with recovery boiler operation to maximize liquor throughput, increase uptime and increase the longevity of the equipment.
• Increased knowledge in lime kiln operation, design and maintenance to optimize day to day operation and troubleshoot common issues such as ringing and mud balls.
• Better understanding of the software available to improve evaporator design, reduce fouling and deposits.
• Gain knowledge on software and equipment available to improve green liquor quality and throughput as well as white liquor quality.
