Major Paper Mill Situational Analysis - Case Study
A major paper manufacturer is a global leader in the paper and packaging industry with operations across North America and around
the world. Its businesses include industrial and consumer packaging and uncoated papers. The company’s mill, located in the Southeastern United States, is one of the most high-yielding paper mills in the world producing light, medium and heavy weight coated paperboard for packaging food, liquid aseptic, tobacco and much more.
The company’s outage planner/reliability engineer for power contacted Recirculation Technologies (RTI) with concerns about the mill’s decreasing water throughput in its water system. To determine both the condition of the resin and any benefits the mill would
receive as a result of restoring the resin, RTI obtained samples from the mill’s water system and conducted pre-treatment tests in its
specialized lab. The mill’s demineralizer system contains four trains of resin: one train (train #2) had been replaced with new resin
before RTI’s “initial” analysis, so RTI only restored the resin in three of the four trains: trains #1, #3 and #4.
To increase ion exchange resin effectiveness and throughput by tracking water system throughput performance over time using prior data during and after two separate resin cleanings.
