New Defoamer Technology Reduces Program Costs and Provides Additional Benefits for Fluff Pulp Producer

GoalReduce program costs and improve defoamer stability issues.

<h6>Improvement Opportunity</h6> <p>A large fluff pulp mill located in North America was experiencing stability issues related to their brownstock defoamer which was leading to inconsistent performance and increased chemical costs. Due to stringent regulatory and mill approvals, the incumbent chemical supplier that had been in place for many years was not making any attempt to keep costs under control or improve performance quality. Once challenged by the mill to improve, they responded with price reductions but did not offer any program improvements.</p> <h6>Recommended Solution</h6> <p>The mill approached Solenis to run a trial against the competitor and demonstrate the value and benefits of our new silicone emulsion defoamer technology. Advantage CS6301 brownstock defoamer is a reduced silicone content, emulsion defoamer formulated to provide an economical combination of drainage and foam control. Application points were re-evaluated. The number of feed points were reduced, and some relocated to maximize the performance of the product.</p> <h6>Results Achieved</h6> <p>Advantage CS6301 resulted in a reduction in chemical use of more than 25% compared to the incumbent&rsquo;s silicone emulsion program. Washer operations stabilized, and deposition potential declined. The improved washing at the brownstock washers also led to increased O2 delignification. The program value was estimated at almost $500k/year in bleach plant savings. Solenis&rsquo; program was able to reduce the mill&rsquo;s costs by $775K per year.</p> <table style="border-collapse: collapse; width: 61.093%; border-width: 1px;" border="1"><colgroup><col style="width: 49.9643%;" /><col style="width: 49.9643%;" /></colgroup> <tbody> <tr> <td style="padding: 5px;"><strong>Improvements</strong></td> <td style="padding: 5px;"><strong>Value</strong></td> </tr> <tr> <td style="padding: 5px;">Program Cost Savings</td> <td style="padding: 5px;">$775,000</td> </tr> <tr> <td style="padding: 5px;">Impact on Bleaching</td> <td style="padding: 5px;">$469,000</td> </tr> <tr> <td style="padding: 5px;">Deposition Reduction</td> <td style="padding: 5px;">Priceless</td> </tr> <tr> <td style="padding: 5px;">Washer Stability</td> <td style="padding: 5px;">Priceless</td> </tr> </tbody> </table>
