2014 Academic Advisory Committee Meeting 

& Senior Design Project Presentations

Thursday, May 15, 2014

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 15, 2014:

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

Chemical Addition System

Students:   Jordan Hansen, Lindsey Hoffman, Adam Offerdahl, Jamie Tauscher

Abstract:
The flexibility of the products, projects, revenue, and education potential of the UWSP pilot paper machine is limited by the lack of a complete, continuous chemical addition system. Without a continuous addition system, a pilot machine cannot represent a full-scale production machine in terms of functionality, efficiency, and product performance.

This project’s goal is to design and implement a modular, continuous, chemical addition system capable of running both acid and alkaline conditions. Dye, size, wet strength, alum, retention aid, filler, and dry strength must be added to the machine in an accurate, adjustable and efficient manner. The system will improve specific paper properties of interest including color, strength, water absorption, grease absorption, retention and then reduce the impact of cross machine direction and machine direction variability. These values will be tested before and after changes are made on the machine using modern physical and optical testing apparatuses. 

Upon completion of the project, the paper machine will not have any production limits due to lack of chemicals. Safety manuals, pump curves, suggested concentrations, flow rates, standard operating procedures, safety data sheets, and proper training will be provided to ensure safety and confident operations for future workers on the machine.


Fiber Blending System

Students:  Brock Brandner, Kelli Hultman, Seth Nelson, Rachel Strelow

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.
