HiCon 2.0 in practice: Mpact benefits from increased capacity and reduced energy requirements
As part of the conversion of the company's paper mill in Felixton to make production ''greener'', recovered paper fibers have been used instead of the sugar cane waste product bagasse since 2015. A machine rebuild was designed to increase the machine speed from 700 to 930 meters per minute, to achieve the goal of a 40 percent increase in production. For this project Voith executed an upgrade of the complete stock preparation unit. Since the completion of the rebuild in 2016, a vertical LC pulper with a capacity of 800 metric tons per day has been added to the existing drum pulper.
The HiCon 2.0 technology builds on these proven concepts but has added two core innovations: First, a sturdy system ensures that discs stay on track, which prevents damage of the segments. And second, each disc is fed separately, the flow pattern in the vat can be reversed. This prevents thickening of the pulp. In conventional disc filters, higher inlet stock consistencies inevitably result in a high degree of thickening in the filter vat. This is why most paper manufacturers dilute the stock flow upstream of the disc filters. This means higher water input and a higher demand of pumping energy.
