Alltech dosing systems support Vajda-Papír’s new tissue production line at the factory in Dunaföldvar (Hungary)
As a showcase investment, the Hungarian tissue manufacturer Vajda Papír has been operating a new tissue machine PM2 since July. Dosing systems by Alltech are a part of this cutting-edge production line with a capacity of 80,000 tons per year.
(PresseBox) - In the two decades since its establishment, the Hungarian company Vajda Papír has developed into one of the fastest-growing tissue manufacturers in Europe. The company supplies customers with diverse tissue products with production sites in Hungary and Norway. In order to continue the course of growth in a focused manner, Vajda Papír has commissioned a new tissue production line in July 2022 at its factory in Hungarian Dunaföldvar, which will expand annual production by up to 80,000 tons.
Dosing systems by Alltech are used by Vajda Papír in process water treatment as well as in the production of absorbent, finely creped sanitary paper from pulp.
Mother tanks and dosing stations for the supply of additives (wet solids) in the production process of sanitary paper
Alltech delivered mother tanks and dosing stations to Vajda Papír as early as May 2022 during the course of the first project phase. As part of the production process of the sanitary paper, various additives are dosed whose task is, among other things, to increase the tensile strength in the wet state (wet strength). Additives also serve to improve the retention of solids on the paper machine wire (retention) and water runoff (drainage) during the manufacturing process.
The mother tanks supplied by Alltech function as storage and dosing system for the safe and efficient handling of standardized IBCs (industrial bulk containers) used by manufacturers when delivering additives. These chemotainers are positioned directly on the tank with the help of a forklift truck or an appropriate lifting device and are emptied into the tank completely. The volume of the mother tank permits the emptying of a complete chemotainer with a fluid reserve of 10-50 percent. In this way, a continuous supply to the dosing system is ensured, and the timing of the transfer process does not have to be monitored precisely.
The mother tank is located in a collecting tray, which protects the operating personnel and the production environment from leaking chemicals in the event of a leak. The dosing stations are mounted on a wall mounting plate or console and are used for dosing chemicals into various process sections of the paper production.
Preparation of polymer concentrate and dosing of the retention agent into the manufacturing process and for process water treatment.
During the paper production, the components, which will later become the paper, are applied to a sieve as a diluted, watery slurry and filtered. This process of filtration is improved and partly accelerated by retention agents.
“In this process, the quality of the polymer solution is crucial and has a direct impact on the paper quality.” adds Ladislaus Bach, Head of Marketing and Distribution of Alltech Dosieranlagen GmbH, who was in charge of this project.
In a second project phase, Alltech delivered another mother tank and a CONTINUFLOC dissolving and dosage system with EMMI (an electromechanical mixing system to save polymer concentrate), as well as three dosing stations. One dosing station supplies the flotation system (DAF) with a polymer solution for the treatment of process water. The two other dosing stations supply the retention of the paper machine with a polymer solution.
CONTINUFLOC systems are fully-automated two-chamber pendulum plants for polymer preparation. For specific applications with an increased requirement, the CONTINUFLOC can also be equipped with an EMMI electromechanical mixing system. This is characterized by an optimum concentrate mixture and, therefore, maximum efficiency. This results in reduced material and resource consumption. The dissolving and dosing system used at Vajda Papír provides a maximum of 4,000 liters of ready-to-use polymer solution per hour.
Ladislaus Bach describes the project with Vajda Papír in retrospect as a convincing success: “It was a picture book launch! Careful planning, good preparation, and an experienced team enabled the new production line to start up smoothly and on schedule at the specified time."
