Ahlstrom-Munksjö and Via Separations partner with the U.S. Department of Energy to enable energy efficiency
The Ahlstrom-Munksjö Mosinee plant in Wisconsin is teaming up with Via Separations to pilot a cutting edge energy efficiency project. Together, they are validating Via Separations’ Black Liquor Concentration System, which is driven by an innovation in membrane material and system design. Black liquor is the byproduct from the kraft process when digesting pulpwood into paper pulp removing lignin and other extractives from the wood, to free the cellulose fibers and allow for the papermaking process to occur. The new system will reduce energy requirements for this process, increase mill throughput, and increase production of coproducts which are used as a heating source for the plant. “In partnership with the U.S. Department of Energy’s Industrial Technology Validation program and Ahlstrom-Munksjö, Via Separations is proud to support this trial. We can reduce the resource requirement per unit of pulp produced by implementing a step change process intensification,” said Shreya Dave, CEO of Via Separations. "At commercial scale, the technology has the potential to provide a 64% decrease in energy demand in the evaporator process."
