New High Efficiency Direct Dye Reduces Chemical Costs at Linerboard Mill

GoalReduce chemical use and program costs.

<h6>Improvement Opportunity</h6> <p>A linerboard producer located in North America was experiencing increased tinting costs while utilizing a competitor&rsquo;s direct dye product.&nbsp;</p> <p>Solenis has been promoting and successfully commercializing a new anionic direct dye, Pergasol Orange 80LN, as a more cost-effective alternative to the competitor&rsquo;s offering.&nbsp; Trials and commercial applications with Pergasol Orange 80LN have shown a considerable strength advantage at equal a*-value.</p> <h6>Recommended Solution</h6> <p>Solenis met with mill personnel, including the mill&rsquo;s Quality Manager, and Product Development at Corporate Research.&nbsp; A lab study was proposed and conducted at the Wilmington Research Center comparing Pergasol Orange 80LN against the incumbent product.&nbsp; The results of the lab study showed that switching to Pergasol Orange 80LN would result in a 50% dosage reduction to meet the 7.5 a*-value target.&nbsp; Solenis proposed a dye trial utilizing the mills existing dye system.&nbsp;</p> <h6>Results Achieved</h6> <p>The following key performance indicators were agreed upon and codified prior to the trial:</p> <ul> <li>Ease of handling and pumping. <em>No issues noted</em></li> <li>Run to target a*-value of 7.5. &nbsp;&nbsp;&nbsp;<em>Achieved</em></li> <li>Dosage reduction of 40-50%. &nbsp;&nbsp;<em>Achieved</em></li> </ul> <h6>Paper Machine Specifics</h6> <ul> <li>2-ply Fourdrinier</li> <li>Production Rate: 80+ TPH</li> <li>Furnish: 100% OCC</li> <li>Neat dye addition at screens to top ply</li> </ul> <p style="text-align: center;"><img style="max-width: 100%; width: auto; height: auto;" src="/link/e05152aa3c6a47d3ac4474bfea30c848.aspx" alt="" width="1068" height="512" /></p>
