2015 Academic Advisory Committee Meeting 

& Senior Design Project Presentations

Thursday, May 14, 2015

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 Gerry Ring, 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 14, 2015:

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

Optimization of the production of RiverPointTM printmaking art paper

Students:   Fred Dorn, Kory Kleuskens, Huel Sanders, Stevens Swan

Abstract:
RiverPoint art paper, which is a 100% cotton-fiber paper produced at UWSP is currently sold to an outside customer, so product quality is of utmost importance. During a typical production run, approximately 50% of the paper produced is rejected, resulting in large manufacturing costs. The major causes of rejects are machine direction basis weight variations, sheet width variations, and debris on the sheet. Basis weight accounts for 49% of the total rejects, debris 47%, and width another 4%. From this we decided to focus on reducing the machine direction basis weight variability. 

We researched causes of machine direction basis weight variability, and consulted industry professionals, comparing our findings with what we observed on the paper machine.  We observed consistency variations in the stuffbox up to 0.5% which we traced back to consistency variations in stock tank 1. We plan on purchasing and installing a microwave type consistency meter to replace our current blade type consistency meter to control our consistency coming out of stock tank 1. We estimate that better consistency control will reduce rejects on the machine by 12% and other low cost operational changes could potentially reduce rejects up to 20%. This reduction will result in approximately $7500 in savings on the machine per year.


Energy and Water Use Reduction

Students:  Lucas Berg, Tyler Shimulunas, Isaacc Silvernale

Abstract:
The system in place currently is unable to control fiber length distribution from the stock tanks to the headbox.

The current fiber blending system is unable to communicate to the pilot paper machine control system.  The Morfi fiber analyzer currently tests fiber delivered through samplers on the stock tank #1 line and the outlet of the mix tank.  The Morfi is unable to send fiber length distribution results to the process control system.  The control system uses manual fiber length distribution calculations to control flows from both stock tanks to achieve the fiber blend set point.  Previous seniors were unable to connect the Morfi results to the process control system, because there is not a software program for the task.  In order to have a fully automated fiber blending system, the fiber length distribution results must be delivered to the control system.

Our group will implement a functional fiber blending system, which will measure the fiber length distribution in the mix tank and incoming flows from the stock tanks to achieve the desired fiber length distribution.
