2016 Academic Advisory Committee Meeting 

& Senior Design Project Presentations

Thursday, May 19, 2016

The Paper Science & Engineering Academic Advisory Committee (AAC) Meeting is an annual event held each spring.

Each year, representatives from the paper and allied industries gather with the Paper Science & Engineering faculty and staff to listen and assess the Senior Design Project Presentations and provide students with constructive feedback on their projects.  After the presentations the committee meeting begins with an update from Karyn Biasca, Department Chair, on the status of the Department where industry representatives input on curriculum is welcomed.   The AAC meeting is followed by a Luncheon for participants. 

There is no cost to attend this event, but pre-registration is appreciated so that we may plan for food and presentation spaces.


The schedule for May 19, 2016:

8:30 am Check-in begins

9:00 am Student Presentations

10:30 am Academic Advisory Committee meeting

12:30 pm Luncheon



 

Senior Design Project Abstracts

Improve the Operation of the Paper Machine Save-all

Students:  Katherine Ebensperger, Les Hillberg, Ryan Pearce, Dustin Ziegelman

Abstract:

The functional properties of a fractionating saveall have been studied and optimized for improved separation and accept fiber consistency. Fractionating savealls are designed to separate whitewater into both useable fibers and water containing the filler and fines. This allows the fines and filler to be removed from the system to prevent adverse effects on the wet end of the paper machine while returning the useable fiber to the stock stream to decrease overall wet-end fiber loss. Inlet flow rate and nozzle angle, each of which have collaborative effects on the rotational velocity of the screen, proved to be important, measurable parameters.  A 45o and 90o alternating four-nozzle arrangement with inlet flow greater than 50 gpm was shown to be most effective. The alternating nozzle angles induce an artificial nozzle height difference, creating a dual de-watering zone while producing sufficient centrifugal force that results in fiber accepts of 2.5% consistency or greater. Inlet consistency, or non-water solid composition, is shown to have little to no effect on the proper functionality of the fractionating saveall. Ultimately, inlet flow rate, nozzle angle, and nozzle height are crucial components to running an optimized fractionating saveall system


Optimize the Performance of the Compressed Air System in the Paper Machine Lab

Students:  Daren Bibeau, Joseph Brown, Jacob Reckamp, Matthew Zimmerman

Abstract:

Compressed air is a critical, often overlooked system to any modern paper machine.  From uses as precise as pneumatic valves to functions as simple as an air nozzle, a well maintained pneumatic system benefits every aspect of production.  This project sought to reduce the energy use of the UWSP Student Run Paper Machine’s pneumatic system.  This was done by analyzing the system from compressor to end use looking for potential energy waste.  Issues were identified as wasteful air use in the wire and felt guide systems, as well as leaks at pipe elbows and joints.  These problem applications were mended and replaced with more energy efficient systems.  This led to a reduction in the energy use of the pneumatic system and reduced load on the air compressor.
