PI Users Conference 2000 29
Capacity IncreaseAvoided Costs
• Refrigeration Bottleneck• PI Data Used to Investigate 25% Refrig
Increase– Upset data helpful– 4 Refrig users have opportunities for reduced
demand– Refrig machine operating parameter change
• Looks like new Refrig machine not necessary - $1.2 million cost avoided
![Page 30: PI Users Conference 20001 Elf Atochem North America Calvert City, Kentucky.](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649ef55503460f94c08984/html5/thumbnails/30.jpg)
PI Users Conference 2000 30
Redirected Costs
• A number of routine reports have been automated
• Allows people freed from reporting tasks to use their talents more productively
• Reduces labor cost that can be used for other purposes
• Provides information that would be almost impossible if done manually
![Page 31: PI Users Conference 20001 Elf Atochem North America Calvert City, Kentucky.](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649ef55503460f94c08984/html5/thumbnails/31.jpg)
PI Users Conference 2000 31
Redirected Costs
• Shift Superintendent Report– 1/2 hour per shift now spent on running plant– $18,200/year
• Daily production report eliminated 1/2 time clerk at one unit– $26,000/year
• Unit monthly quality report
![Page 32: PI Users Conference 20001 Elf Atochem North America Calvert City, Kentucky.](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649ef55503460f94c08984/html5/thumbnails/32.jpg)
PI Users Conference 2000 32
Redirected Costs
• Automatic batch reports– Reports now done daily– Timely information to improve quality– Supervision/Clerk savings $18,000/year

PI Users Conference 2000 33
Redirected Costs
• Incinerator trip report– Permit renewal requires human health risk
assessment– Dependent on “Upset Time” with default value
of 20%– DataLink used to document trips and upset time– Even with ProcessBook this task very labor
intensive– Report showing upset time significantly < 1%
![Page 34: PI Users Conference 20001 Elf Atochem North America Calvert City, Kentucky.](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649ef55503460f94c08984/html5/thumbnails/34.jpg)
PI Users Conference 2000 34
Intangible Returns

One User’s Comments
“Simplifies and Distributes access to DCS information five fold.
Conceptually simple tasks are actually simple compared to DCS, such as creating a new trend display or doing some calculations on data available within the DCS. This can take days for the DCS depending on the availability of the DCS engineer. It can be done in minutes in PI.”

“Before PI, when I got a call at home on a process problem, the only way to solve it was to get in the car and drive an hour to the plant. I now have access to PI from home and have access to all of the data that is available in the control room. I can usually provide guidance to the operator needing help. This not only saves me lost sleep and long drives, but the problem gets solved an hour earlier. This can mean avoiding lost production.”
