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 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 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
Fred Dorn, Kory Kleuskens, Huel Sanders, Stevens Swan
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
Lucas Berg, Tyler Shimulunas, Isaacc Silvernale
Targeting reductions in water and energy usage is critical in industrial processes, so the purpose of this design project is to lower operating costs and create a smaller environmental footprint for the pilot paper machine on our University of Wisconsin - Stevens Point campus.
Reducing water usage will be achieved through clarifying and reusing currently sewered process water for freshwater applications. These applications will include process water sources for the wire knock-off showers, wash-up hoses, and couch pit dilution. This project could save on water usage by up to 720,000 gallons per year.
The energy side of the project will investigate pocket ventilation applications on the paper machine. This would increase the mass transfer rate of water evaporating out of the paper web in the dryer section of the machine. The pocket ventilation will supply warm, dry air to targeted pockets in the dryer sections to replace air otherwise fully-saturated with moisture and steam. The result would be more efficient water transfer, thus an increase in steam usage efficiency leading to less steam usage overall. The resulting increases in efficiency will then be determined based on current energy and mass balance audits being performed.
The Academic Advisory Committee meeting is NO cost to you,
