Case Study: Background Lanxess
Born of Bayer AG strategic realignment in 2004 Produces Performance Chemicals, Chemical Intermediates,
Engineering Plastics & Performance Rubber Sarnia, Ontario Plant: Butyl Rubber producer >60 years Moisture analysis & control is key Process Engineers & Plant Operators lacked confidence
in analyzer results due to Sample Handling System (SHS) legacy problems
Plant shutdowns resulted – big bucks lost on several occasions!
![Page 4: “How to Trust Your Process Analyzer"](https://reader036.vdocuments.us/reader036/viewer/2022062315/568159e7550346895dc7320a/html5/thumbnails/4.jpg)
Analyzer PM had been properly completed within 48 hours of a moisture increase trend
Midnight callout from operations: “Your Analyzer Isn’t Working!”
Analyzer Engineer twisted operations arm over the phone: “Act On The Analyzer’s Results!!!”
Operations listened- and set a new production record that very day!
“High-fives” for everyone- but Analyzer Engineer reminded the team about the “dodged bullet”
Cross-functional team was created to increase SHS reliability and “customer confidence”
Case Study: Early 2004

New Tools for SHS Reliability Robust, modular, remote actuation double block
& bleed stream (DBB) switching valve

New Tools for SHS Reliability Differential pressure
flow indication w/ integral relief function (I.S., 4-20mA output)

Field Results
Process Engineers & Operations TRUST THE ANALYZER
Several analyzers in the Sarnia plant are running closed loop control
Plant Shutdowns HAVE BEEN AVERTED
5 additional “smart” systems have since been commissioned in the Sarnia plant- more planned

Next Steps
Incorporate Human Machine Interface (HMI) in field; Class 1, Division 2 compliant
Provides local host for “Smart Shelters”
