NewswireTODAY - /newswire/ - Heidenheim, Baden-Württemberg, Germany, 2019/01/14 - Hamburger Rieger has engaged Voith to supply the complete stock preparation unit for its new PM 2 in Spremberg, Germany - Hamburger-containerboard.com / Voith.com. FSE: VO2A

• OnEfficiency.DIP ensures high raw material quality and low running costs;
• Efficiency concept used for the first time for the production of packaging papers;
• Automatic adjustment of flotation technology and input of chemical additives;
• Virtual sensors predict contamination areas.

Voith will deliver three separate stock preparation lines with a total capacity of 2,450 metric tons per day. Meri Environmental Solutions is responsible for the complete reject and water treatment facility.

The key to the stock preparation concept is the OnEfficiency.DIP (deinked pulp: recycled waste paper without color residues) system from Voith, which has already proven effective for the manufacture of graphic papers based on recovered paper. The efficiency concept is now being used for the first time in the production of packaging papers. In the stock preparation unit of the new PM 2, ultra-modern sensors and actuators ensure consistent raw material quality and low running costs.

The system consists of two DIP yield control modules, two DIP bleach control modules and a DIP optimizer. The DIP yield control module uses online sensors to measure the ash content and whiteness of the DIP stock. Using actuators, the flotation technology automatically adjusts it as necessary to obtain the required degree of whiteness. The DIP bleach control module also measures the whiteness before and after a bleaching step. If necessary, actuators also regulate the flow of chemical additives here as well. The control modules are connected with the DIP optimizer, which defines optimum target values based on the optimization of running costs. The cost model takes account of relevant parameters such as energy, raw material and chemicals. This dynamic interaction between the individual components reduces quality fluctuations, which occur thanks to the heterogeneity of the raw material or production adjustments. This at the same time improves production costs.

In the PM 2 in Spremberg, Voith is also testing a new prototype of a virtual sensor which uses the measurements in the stock storage tower and the process parameters to predict contamination areas. The DIP optimizer uses the model calculated in this process to optimally adjust the variables. The self-learning system allows for automated controls, which means that the full potential of the system can be reached sooner.

At present, only the OnEfficiency.DIP from Voith offers this kind of comprehensive performance. According to Hamburger Rieger this was a decisive factor in awarding the order for the stock preparation unit. With a tailored service package, Voith ensures that the OnEfficiency system will continue to perform optimally in the long term.

Following a groundbreaking ceremony on 26 September 2018, work began on Hamburger Rieger's new paper machine in Spremberg. From June 2020, the 7.8 m wide PM 2 will produce up to 500,000 metric tons a year of White Top Testliner with various basis weights. The two-loop DIP line produces the white top layer of the WTTL (White Top Test Liner). The paper manufacturer has opted for a particularly environmentally friendly de-inking system for stock preparation.

Hamburger Rieger (hamburger-containerboard.com) is investing around EUR 370 million to build the PM 2 and is creating more than 200 new jobs in the Lusatia region. Hamburger Rieger is part of the Hamburger Containerboard Division of the Austrian Prinzhorn Group, whose annual production of more than two million metric tons makes it one of the market leaders in the segment for white uncoated and coated testliner.
