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.

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