International technology group ANDRITZ has received an order from Mpact Operations (Pty) Ltd. (“Mpact”) to upgrade a pulping line at its Mkhondo Paper Mill in Mpumalanga, South Africa. The upgrade will boost the line’s capacity and improve the strength properties of the product. This will help the customer respond to the strong domestic and international demand for high-quality sustainable packing solutions.
As Brian Smith, project director, Mpact explains: “With the technological solution proposed by ANDRITZ, we can increase our mill’s performance and make our production more sustainable at the same time. In addition, we get everything from a single source – three good reasons for choosing ANDRITZ as a partner.”
ANDRITZ will upgrade the entire neutral sulphite semi-chemical pulping (NSSC) line, which processes eucalyptus and pine to provide fluting and linerboard for the production of containerboard. The comprehensive ANDRITZ solution comprises key equipment for the wood processing, cooking, washing and refining sections to increase the line’s capacity from 225 bdmt/d to 365 bdmt/d and at the same time enhance product quality.
· A new chipping line will provide excellent chip size distribution to secure a homogenous cooking result with minimal amounts of fines for improved material efficiency.
· The conversion of the cooking system will maximize fiber quality and pulp cleanliness.
· The use of clean condensate to generate fresh steam for chip pre-steaming will provide clear environmental benefits in terms of fresh-water usage and primary steam utilization.
· Excellent washing results with the new generation Compact Press technology will lead to high humidity resistance of the product.
· ANDRITZ TwinFlo Prime refiners will optimize the fiber quality prior to washing and thus the product quality. Using water-lubricated bearing technology, the latest LC refiner innovation allows a more environmentally friendly operation.
· ANDRITZ PrimeFilter D will ensure superior preparation of clear and super clear filtrate.
ANDRITZ will also provide the supervision over the erection, commissioning, and start-up as well as the training of the operating personnel. Start-up of the upgraded line is scheduled for the first half of 2025.
