 Furnish Homogenization for Pulping Applications

Walter D. Lampp, III, North American Area Manager, FMW Austria

Given today’s demanding pulp and paper environment, it is increasingly important to maximize process efficiencies at every level. Beginning in 2000 with the introduction of Blending Bed Stacker/Reclaimers, a tool is now available to efficiently and economically homogenize furnish in order to maximize digester performance.

The presentation will cover blended bed stacker/reclaimer technology in detail including design

FMW Blending Bed Technology is specifically designed for homogenization of wood based furnish with regard to age, moisture content, quality, source, and species. This requirement is accomplished during both stacking and reclaiming operations of its integrated blending zone.

Other advantages of this technology covered in the presentation will include its first-in-first-out operation, full automation, and 100% active storage volume.

A Safer Boiler is a Greener Boiler--BLRBAC Compliant BMS for BLCR Boilers

Larry Wells, Controls Specialist (ISA Distinguished Society Award Recipient)

• ring header purge - how often - why automate?
• local light off of startup and load burners as required by BLRBAC - buy packages like we used to - I/O reduced from 17 to 7 per igniter on typical installation - big savings in wiring costs - simplified troubleshooting and maintenance
• Trifecta-like valves - minimized piping, wiring, I/O - "all or nothing reliability"
• ESP / Rapid drain system - minimized cost / increased reliability
• Divert system turn-key solutions - several vendors
• Use DCS for true "single window" but with "separation" as required by NFPA - not PLC, or vendor proprietary FSSS system

Industrial Green Liquor Implementation: Startup, Monitoring, and Results

by Lucian Lucia, Peter Hart, & Sujit Banerjee

presented by Lucian Lucia, Ph.D., North Carolina State University

The process of green liquor pretreatment before digestion is gaining more and more attention as a viable way to not only offload the kiln, but to produce a stronger and higher yield pulp.  This presentation will review lab and industrial work on the process and mechanisms behind green liquor pretreatment and what elements are necessary to constitute a successful trial.

Breaking the Yield Barrier--Kraft Pulping - Where do we stand and what has happened?– a review of the past, current and future practices within the kraft pulping technology

Author :          Anders Hjort, Metso Paper, Karlstad, Sweden

Even if the kraft pulping process has a history spanning more than 100 years, a lot of the technology applied in new mills has been developed during the last 10 – 15 years. Developments in material technology and process control combined with a better understanding of the chemistry involved have opened up possibilities to increase the size of the plants, to increase the yield, to reduce the energy usage, to reduce emissions and to optimize certain pulp/paper properties and thus make a pulp more suitable for a specific customer needs.

This paper will, in short terms, describe what possibilities we have to optimize older kraft continuous digesters by applying new technology in order to optimize the process with respect to the above mentioned parameters and properties.

Re-evaluating Paradigms for Innovative Breakthroughs--The Development of a New Pulping Process

by Dr. Peter W. Hart, MeadWestvaco

A modified kraft pulping process has been developed that successfully breaks the traditional hardwood kraft pulp yield barrier. The process produces fully bleached, high brightness hardwood kraft pulp with a yield of greater than 53% on wood. Details of the development and processing steps, along with various recovery cycle impacts, are discussed.

Review of Oxygen Delignification to Offload Kraft Pulping

by Lucian Lucia and Bindu Dhasmana

presented by Lucian Lucia, Ph.D., North Carolina State University

The use of a O2 stage to improve the final bleachability of pulp is an option that adds cost to the mill for environmental benefits, but does it add to the bottom line regarding product benefits?  This review will explore this latter question by reviewing the tangible benefits of implementing oxygen delignification in a mill setting.

A Review of Rapid D₀-Stage Bleaching:  A Method to Simplify Bleaching and Reduce Bleach Plant Capital

Brian N. Brogdon, Ph.D.

Senior Consultant

FutureBridge Consulting & Training, LLC

This talk will review the work of McDonough, Courchene and Baromes (US Dept. of Energy, DE-FC07-971D13562) regarding rapid D₀-stage (D₀^R).  Rapid D₀ is a chlorine dioxide delignification stage that is operated for one to five minutes, versus 30 to 60 minutes for a conventional D₀.  The D₀^R process utilizes a high-shear mixer followed by a short retention tube or pipe.  The resulting pulp is washed, extracted with alkali (e.g., (EPO)-stage), washed and subjected subsequent brightening.  This technology is readily adaptable to the “simplified bleaching process” developed and advocated by Jack Histed, which utilizes a eight-minute D₁ brightening stage, one-minute E₂-stage, and a standard D₂-stage without interstage washing ( i.e., (D₁/E₂/D₂).  The bleach sequence D₀^R(EPO)(D₁/E₂/D₂) can produce fully-bleached softwood pulps to 85% ISO brightness and hardwood pulps to 89% ISO brightness without negative impacts on pulp strength.  Laboratory and mill trial data from the McDonough, Courchene and Baromes study will be presented to demonstrate the feasibility of this bleaching process.  This bleaching process can be easily retrofitted into an existing bleach plant with low capital cost and smaller footprint; the retrofit can free-up an additional bleaching tower and/or bleach washer to be utilized elsewhere in the sequence, if needed.        

5:45   LGMI to the Max! The Institute's current vision of the LGMI Machine will be unveiled. Of special note--the Institute believes a machine built to these parameters will never suffer from the locked in width constraints current paper machines experience.

Latest Energy Savings Ideas for all Papermachines

Dick Reese, Dicke Reese and Associates

Energy consumption on paper machines varies widely. Energy benchmarks have been developed for major grades of paper and energy consumption on “average” paper machines is 20% higher than on top performing machines. Paper machine energy scorecards have been developed to benchmark current energy use and help identify opportunities for improvement. Energy surveys have identified annual energy savings opportunities ranging from $100,000 to $10 million on individual paper machines. Typically about 25% of energy savings opportunities can be achieved with no capital expenditures. Cost of energy averages 20% of paper manufacturing cost but ranges from 10 to 40% depending on energy efficiency and cost of purchased energy. Key factors in minimizing energy use are tight water systems, efficient press section operation, good steam and condensate system design, and recovery of heat. Energy use should be considered when paper machines are rebuilt or new machines installed.

Process Solutions to Improve Paper Machine Performance

Frank Cunnane

Product Manager, PMC and Instruments

Cristini North America

Advancements in instrumentation have opened new avenues for effective use of vacuum table elements to control sheet consistency for a variety of papermaking applications including dandy rolls for improved formation, multiple formers for optimum formation, coverage, and ply bond, as well as numerous chemical dosage applications.  Outdated nuclear radiation mass measurements have proven unreliable and inaccurate in critical situations.

Also, monitoring machine clothing on today’s machines has presented a new variety of safety and environmental concerns.   New instrumentation technology from Cristini allows real time outputs for clothing moisture content and permeability without requiring operators and technicians to make separate on-machine measurements in dangerous locations.  Such practices have been banned in many corporations. Cristini has developed fixed point and/or traversing measurement heads that allow BlueTooth connection to free-standing “black box”, or direct connections to the machine’s own DCS/MCS systems for data analysis.  Fast Fourier transformation (FFT) capabilities are included with this line of instruments, providing near instantaneous read-out of pulsation or vibration issues.

Press fabrics are simultaneously monitored for moisture content and permeability, while forming section analysis of moisture levels allows for immediate read-out of changes made to improve wet-end performance. Unlike current forming moisture measurement technology, Cristini instruments do not utilize radioactive sources which inherently incur significant record-keeping, safety and disposal costs.  A technical analysis of Cristini microwave technology vs. the older gamma radiation technique is presented.
