GoalDrainage Aid Improves Production in a Semi-Chemical Pulp Mill

<h6>Customer Challenge</h6> <p>An Asia Pacific semi-chemical pulp mill had a drainage related production bottleneck at their brown stock washers. Process equipment included DD-Washers and GFF vacuum filtration.</p> <h6>Recommended Solution</h6> <p>After completing a process survey and lab testing, the Solenis team recommended adding Advantage BN3398 defoaming agent chemistry to the inlet of the washer at a rate of 0.29 kg/ADT.</p> <h6>Results Achieved</h6> <p>Drainage on the washers improved as indicated by a 13% reduction in washer rpm. With the drainage bottleneck removed, this customer was able to increase production by 8.6% or 50 ADT/day. No negative impacts were observed on pulp quality or system deposition.</p> <p><img style="max-width: 100%; width: auto; height: auto; display: block; margin-left: auto; margin-right: auto;" src="/link/50f5c5aff09d40b3b314752018b75f75.aspx" alt="" width="800" height="568" /></p>
