Converted Newsprint Machine Producing Virgin Linerboard Increases Recycled Content and Productivity

GoalIncrease recycled content and improve paper machine productivity.

<h6>Customer Challenge</h6> <p>A packaging customer located in North America wanted to achieve higher Ring Crush Index on their 31 lb linerboard to allow for increased old corrugated container (OCC) utilization and improved paper machine productivity. The customer&rsquo;s paper production is limited by their pulping capacity and the paper machine is dryer limited. Achieving a higher OCC percent will allow the paper machine to increase output by eliminating the pulp mill bottleneck and has the added benefit of reducing total refining energy per ton.</p> <h6>Recommended Solution</h6> <p>Solenis recommended their dry strength aid, Hercobond Plus 555, to be added at 8 lb/ton replacing a competitive g-PAM that did not provide additional strength build above 6 lb/ton.</p> <h6>Results Achieved</h6> <p>Hercobond Plus 555 provided higher ring crush, allowed the use of more OCC, and facilitated the production of more finished board.</p> <table style="border-collapse: collapse; width: 99.2603%; height: 183.996px; border-width: 1px; margin-left: auto; margin-right: auto;" border="1"><colgroup><col style="width: 25.1801%;" /><col style="width: 25.1801%;" /><col style="width: 25.1801%;" /><col style="width: 24.6731%;" /></colgroup> <tbody> <tr style="height: 36.9961px;"> <td style="height: 36.9961px; padding: 5px;">&nbsp;</td> <td style="height: 36.9961px; padding: 5px; text-align: center;"><strong>Incumbent </strong><strong style="font-size: 0.875rem;">g-PAM</strong></td> <td style="height: 36.9961px; padding: 5px; text-align: center;"><strong>Hercobond Plus 555</strong></td> <td style="height: 36.9961px; padding: 5px; text-align: center;"><strong>Customer Benefits</strong></td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Reel Speed</td> <td style="height: 21px; padding: 5px; text-align: center;">2180 FPM &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">2269 FPM</td> <td style="height: 21px; padding: 5px; text-align: center;">89 FPM</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">MSF*/Day</td> <td style="height: 21px; padding: 5px; text-align: center;">75,300 &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">78,400</td> <td style="height: 21px; padding: 5px; text-align: center;">+3,000 MSF/Day</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Ton/Hour</td> <td style="height: 21px; padding: 5px; text-align: center;">55.4 &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">57.7</td> <td style="height: 21px; padding: 5px; text-align: center;">+2.3</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Ring Crush &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">66.7</td> <td style="height: 21px; padding: 5px; text-align: center;">67.2</td> <td style="height: 21px; padding: 5px; text-align: center;">0.5*</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Increased OCC % &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">53% &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">60%</td> <td style="height: 21px; padding: 5px; text-align: center;">Eliminate Pulp Mill Bottleneck</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Virgin Fiber Savings &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">NA</td> <td style="height: 21px; padding: 5px; text-align: center;">1.0 lb/MSF</td> <td style="height: 21px; padding: 5px; text-align: center;">~ 40 Ton/Day</td> </tr> <tr style="height: 21px;"> <td style="height: 21px; padding: 5px;">Chemical Cost ROI &nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">&nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">&nbsp;</td> <td style="height: 21px; padding: 5px; text-align: center;">&gt; 3 to 1</td> </tr> </tbody> </table>
