Process optimizer for mechanical pulping

The Process Optimizer is a technology at its best, a product that improves operation of pulping processes and continuously complements the quality of existing processes – on-line.

Bright solutions are often simple. An optimization method that is almost too good to be true. Using the Process Optimizer, will increase your profits.

How to reach the goals

It's about maximizing the efficiency, increasing production and eliminating bottlenecks. It's also about reaching more consistent quality and thereby a better result. At the same time it's about saving money and avoiding unnecessary cost, and emissions. Of course it's best to make the most out of the process – improving profits while at the same time being environment-friendly. Often goals are so contradictory that achieving them seems impossible. However, there is a solution.

Up to...

  • 50% reduction in fiber property variation
  • 10% production increase
  • 5% less energy consumption
  • 50% reduction of shive content  

Other benefits

  • The possibility of minimizing shives, and maximizing average fiber length
  • Easy to establish the relative order between cost, quality and production
  • The adaptive system always finds the best settings (e.g. after a segment change)

 

Profitable process optimizer

Today, companies must invest in a flexible and continuously optimized process, which is both automatic and remote-controlled. This is the first step toward an optimized economy.

Each improvement in the process quickly generates a lot of money. Results immediately become better. Quality is guaranteed. Production costs are also reduced when taxes for environmental impact are decreased through the reduction of effluents and emissions.

Is constant
An optimization can never ever be fully achieved. Efforts at optimizing should continuously search for better settings to be able to handle changes and variations in the process. Complex production processes in the pulp industry are considerably more variable than you first may think. Equipment wears out, the quality of raw material varies and the correcting units are renewed. To reach optimum process operation requires conducting optimization efforts regularly. Valmet Process Optimization provides an optimization strategy that always strives towards the optimum.

Automatic
A real optimization looks for the best settings – in all directions at the same time. A constantly progressive result evaluation is a requirement when making changes in the process automatically. If the optimization is ended when the goals are reached, there is a risk that the improvement is valid for a limited time. Valmet Process Optimization works in “real time” and locates the peak of the process settings – without roundabouts. Each control variable is interrelated, so if you want to consider different goals, such as increased production and reduced costs, you have to search for the best settings in many different directions.

Safe
An optimization strategy has to be safe. It can’t involve any risks or potential delays. It’s all about getting into and improving an already working process and making it work even better. You can gain a lot by optimizing the process from the beginning. Let Valmet Process Optimization continuously search for the most secure way to look for the best operating conditions and adjust (step by step) the concentration flow, etc. The method is fast, simple and effective – and useful in many different fields.

 

Refiner optimizer

Valmet Refiner Optimizer offers the complete system solution for direct, continuous and automatic optimization of processes.

Our scientifically proven technique makes your process continuously strive for the best operating condition and the best results. It evaluates different settings, handles several variables in the process and works gradually towards the goals you want to obtain. The brilliance is that the Valmet refiner optimizer concept allows optimizing towards several goals at the same time.

The aim of the installation is to improve pulp quality and increase production. It is possible to add control and optimization of the long fiber and shives as a means to further improve the quality of the end product. Valmet Refiner Optimizer can also be used for steering control and optimize to even long fiber and shives content.

Refiner control
Process variations can have a major impact on product quality. The pulp refining process is a complex process, which can be problematic when attempting to reduce process variation. Many problems arise as several control and response variables affect each other. Valmet Refiner Optimizer is a complex control system that automates the complexity of this system. Valmet Refiner Optimizer realizes the goals of operating refining at the most cost-efficient variable settings, with low process variations.

The system sends control signals to the process

  • Revolution of the production screw
  • Amount of dilution water
  • Gap

 

Screening optimizer

The brilliance of the Valmet Screening Optimizer concept is that it allows an optimization towards several goals at the same time.

The aim of the installation is to improve the quality of the end product by reducing variation in Freeness. It is possible to add control and optimization of the fiber size as a means to further improve the quality of the end product. Valmet Screening Optimizer offers the complete system solution for direct, continuous and automatic optimization of processes.

Screening control
Process variations can have major impact on product quality. The screening process is a complex process, which can be problematic when process variation is to be reduced. Many problems arise as several control and response variables affect each other. Valmet Screening Optimizer automates the complex control of this system.

The Valmet Screening Optimizer realizes the goal of operating screening at variable settings that are most cost-efficient and with low process variation.

The system enables

  • Over 50% reduction in freeness variation
  • Integration into the current screening control system
  • Automated control of screening Using output from process models – does not require a model of the screening process
  • Automated change of optimization targets for different process cases
