We support our metal production clients by providing single-discipline support, professionals to augment their teams, automation upgrades, construction management, and executing design-build projects.
Objective: Our client needed to optimize their mill and came to Hargrove to perform the engineering for a O2 Delignification Project.
Hargrove performed a mill balance using WINGEMS, which allowed the team to design the system that included an Oxygen Stage Reactor, two new Wash Presses, medium consistency pumps, centrifugal pumps, and associated ancillary equipment between the DD washer and bleach plant. The system allowed cooking to a higher K number in the digesters and sending pulp at a lower K number to the bleach plant resulting in steam savings in the digesters and chemical savings in the bleach plant. The project successfully reduced effluent color, BOD, AOX, flow, total dissolved solids, and nutrients. It also reduced shower water to brown stock washing, resulting in steam savings in the evaporators.
Formed by owners, contractors, suppliers and academics in the engineering and construction business, the ECC aims to drive excellence and the long-term success of the industry through networking, innovation, and outreach. Hargrove has partnered with ECC for over ten years, helping the engineering community overcome the greatest challenges facing capital projects industries today.
