Chemical systems improvements for board and paper making

Do you want to move towards low-carbon production

Valmet aims for 100% carbon neutral production by 2030. The Enzymatic Starch Cooking ZE is a zero effluent solution that reduces the carbon footprint and improves process reliability and quality. The ZE process, used in paper and board production, addresses inefficiencies in conventional starch cooking. It consists of two separate preassembled units for dissolving and cooking of surface size starch and binder starch. With the built-in heat recovery and new circulation system, it decreases energy consumption and decreases load and cost for water treatment. The new starch circulation system enables starch powder savings of several tonnes per month and decreases the load and cost for water treatment. 

Key Benefits

• Resource Efficiency: Optimizes footprint and reduces emissions and wastewater.
• Heat Recovery: Collects excess energy for hot water, saving costs and reducing CO2 emissions.
• Patented Circulation Loops: Ensures consistent starch quality and reduces waste.

Modular process for white water treatment 

Valmet Ultrafiltration W process is a solution for paper and board mills to produce colloidal, bacteria-free, ultrapure water from the white water. The main targets are reducing fresh water consumption, improving paper machine runnability and production efficiency, and controlling the energy balance. When a paper machine's showers and process stay clean for a longer time, the need for shutdowns is reduced. This has a significant effect on paper machine efficiency and product quality. A higher process temperature increases drainage, allowing increased paper machine speed and results in increased productivity. Water recycling allows the recovery of heat and raw materials. Valmet Ultrafiltration W helps to enhance the positive effects of recycling.

Ensure clean starch circulation in size press operations

The Valmet Starch Cleaning Booster is an innovative solution designed to prevent the accumulation of dirt particles in size press starch circulation systems. This system is essential for maintaining the quality and efficiency of the sizing process. The starch cleaning booster offers several key benefits such as enhanced screening, space efficient design and automatic backflow washing. The system can be installed while the machine is running, minimizing downtime, and ensuring continuous operation. The starch cleaning booster operates without disturbing the existing sizing process, guaranteeing no pressure variations at the sizer. The typical scope includes a centrifugal pump, OptiScreen RF pressure screens, precise instrumentation, and expert engineering support.
