Evergreen Packaging FINAL update 2014
- 1. Evergreen Packaging Garrett Griffith:Final Update 8/14/2014
- 2. Introduction Garrett Griffith Sophomore at Arkansas Technical University in Russellville Electrical Engineering Major From the White Hall/Pine Bluff Area First summer here at Evergreen

- 4. Roll Data ProjectObjectives: Understand how paper is made Compile information for all rolls on PM2 including Diameter, Cover, Shell, Roll I.D., Crown, Cover Type, Bearings, Materials, ect. Obtain same information for all spare rolls Check for accuracy Place information into Excel Spreadsheet Learn how to use SAP and get information into program Configure a specific spreadsheet for use by Kevin Kidder and Bill Wilson, it will be maintained by them after completion.
- 5. • I spenta considerable amount of time looking through drawings for information on the rolls
- 6.
- 7. Roll Project: CurrentProgress We definitely underestimated the amount of information on the rolls Still in the information gathering phase for the SAP aspect Next step will be to learn SAP and implement information there Spreadsheet for Kevin and Bill complete
- 8. Flowmeter Project Objectives: Determine where the Mill’s water goes Elizabeth began by placing ultrasonic flowmeters on various pipes in the mill to detect flow Out of the 16 placed, 2 did not get a reading The Unfiltered White Water Pipe and the Filtered White Water Pipe (UFWW & FWW) did not deliver a reading Also a flowmeter will be installed in Manhole H on the Boulevard Sewer I took over the Mill Water Usage Monitoring System Project from Elizabeth Lott due to pregnancy
- 9. Using Siemens PortableFlowmeter I also learned how to utilize specific instrumentation this summer Using the Siemens Portable Flowmeter to measure flow on power house fire water pump 7/8/14
- 10. Flowmeter Project: CurrentProgress We proceeded to try different manufactures flowmeters to determine if it was a mechanical failure that caused no reading We determined that there was not enough water in the pipe to use an ultrasonic flowmeter Orifice plates were then selected Installation was completed by Turner Electrical Work was completed by Evers

- 12. Flowmeter Issues The onlyissue encountered upon start up of PM2 was a small leak. After tightening of the bolts the problem was resolved
- 13. Flowmeter Electrical Evers running conduit for wiringof flowmeters 7/9/14
- 14. Flowmeter Project: CurrentProgress After setting up Process Control we discovered that the measured flow was outside of the transmitter’s ranges Higher ranged transmitters were selected and received from the storeroom When Rudy (Experitec) and I got ready to install the new transmitters it was discovered that the low side valve of the orifice plate was closed. This caused backpressure that sent a reading of much higher flow than was actually the case. Also one of the transmitters was ranged wrong to begin with on the instrument side After fixing the mistakes and watching the readings for a couple of days, all readings are normal, accurate, and in range
- 15. Manhole H FlowmeterProgress Began discussion with Rudy de Anda of Experitec for specifications of manhole and outfall This flowmeter will be wireless with a ten year battery lifespan and utilize a wireless gateway Currently waiting on parts to arrive Next step: install flowmeter, mount gateway and run cat5 and 24V power to caustic plant rack room, then incorporate into PI

- 17. Core Shrinkage StudyObjectives: Evaluate the normal shrinkage of a core for the extruders Determine a way to minimize core shrinkage or at least get some data from which we can adjust our asking cuts on the cores
- 18. Core Shrinkage StudyCourse of Action A meeting was conducted with Sonoco, Nero Haralalka, Rob Luter, Andrew Blue, myself, and others to determine a way to accurately measure shrinkage Our plan was to go to Sonoco and measure 27 cores of different lengths and ages and bring the back to the mill to be measured periodically in different areas of varying moisture and temperature The cores were placed in the core room, humidity lab, and also on the wet end. They were measured in the same 4 positions twice daily for a week while recording temperature, humidity, and time

Based off of this information we were able to adjust our asking cut accordingly.

- 22. What I havelearned Incorporating what I have learned at school into the real world is the most important thing I have taken from this summer at the Mill From talks with people like Mike Cottrell I have gained a better understanding of all things electrical There is a lot that goes into making paper This mill spends a ton of money How to do real research Project Management Not all flow meters are created equal How to ask for help How to look up a loop sheet It is always better to go in the field and look with your own eyes How to write a Requisition and Purchase Order Double check EVERYTHING
