More Days Mean More Pulp

How do you extend uninterrupted operations for your mill’s Kraft Recovery Boilers? What factors currently influence how long your boilers can operate between shutdowns?

Find this and more out when Keijo Salmenoja from ANDRITZ Oy presents Possibilities to Extend Uninterrupted Operations Periods of Kraft Recovery Boilers as part of the Energy, Recovery, Lime Kiln and Recaust (ERLR) track at TAPPI’s Pulping, Engineering, Environmental, Recycling and Sustainability (PEERS) Conference, November 1-4, 2021 in Atlanta, Ga.

Salmenoja’s presentation will look at what is limiting the length of the recovery boiler operation periods between shutdowns and whether these limiting factors are related to safety, perceptions, mechanical constraints, process issues, fouling and plugging, corrosion, local legislation, or recommendations from recovery boiler committees. He will also discuss how to mitigate the effects of these factors.

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 Energy, Recovery, Lime Kiln and Recaust track provides experiences from industrial and academic experts on equipment maintenance, process chemistry and new technologies. Session topics include:

  • Recovery Boiler Online Analysis
  • Recovery Boiler Uptime
  • Lime Kiln Operations
  • Evaporator Optimization
  • Liquor Cycle Efficiency and Improvements

PEERS 2021
PEERS, November 7-10 in Atlanta, Ga., focuses on the latest advances in technology, as well as fundamental process knowledge and control issues mills face each day. The Conference provides mills and other professionals the opportunity to learn from industry experts in a presentation setting, as well as engage in peer-to-peer discussions during panel sessions, committee meetings and roundtables. PEERS also offers multiple relationship-building events and includes an exhibit floor where attendees can speak with suppliers about the latest technologies and solutions.

PEERS 2021 is co-located with the International Bioenergy & Bioproducts Conference (IBBC) and the International Chemical Recovery Conference (ICRC). Attendees can attend the technical programs for all three conferences for only one registration fee. Mills receive special discount pricing. Register today.
