New ABB Strength Virtual Measurement enables mills to optimize quality with accurate, online strength prediction.

ABB has launched Strength Virtual Measurement, an ABB Ability™ Performance Service that enables mills to predict strength properties through accurate online measurements – also known as a soft sensor – resulting in a stronger, lighter product that costs less to produce.

The solution, suitable for all grades, works by leveraging machine-learning generated models to produce online strength calculations for one or more properties at a frequency needed to meet machine-specific requirements. Frequent measurements, with an accuracy that approaches lab results, help operators maintain strength properties closer to their lower limits, reducing raw material usage, increasing machine speed and enabling faster grade changes.

This is delivered through ABB Collaborative Operations, a service which connects production, headquarters and ABB personnel with remote access to ABB digital technologies, data analytics and domain expertise, providing them with the right information to keep operations running. It incorporates ongoing performance monitoring, enabling optimization actions to be implemented in real time to improve the accuracy and robustness of online strength calculations.

“Our new approach to soft sensors combines unrivalled proficiency in advanced analytics, a patent-pending online calculation engine with auto-correlation and ongoing performance analysis to create a virtual measurement with proven accuracy and reliability,” said John Schroeder, Global Product Manager for ABB Ability™ applications for pulp and paper. “With built in performance indices, operators can monitor process parameters, respond to alerts and rapidly adjust paper machine settings to optimize paper strength, reduce costs and increase production throughout, ultimately increasing profitability.”

Strength Virtual Measurement integrates seamlessly with third-party systems and ABB offerings including ABB distributed and quality control systems, ABB L&W Autoline and other ABB Ability™ solutions, providing superior visibility for precise actions to optimize strength properties. It is the first of several new Virtual Measurement soft sensor solutions to be released during 2020 and forms part of the ABB Ability™ Performance Service for paper mills suite, focusing on maximizing equipment and process efficiency.

ABB launches latest digital solution for total control over wet end operations to maximize productivity and profit
ABB has launched the latest generation of its Advanced Process Control (APC) to provide complete digital control over wet end operations, optimizing productivity and profit for paper mills globally.

Wet End Control — an ABB Ability™ APC solution for paper mills — stabilizes the wet end process and reduces variability by controlling, monitoring and optimizing retention performance. It uses a multivariable model predictive control approach to predict future wet end process behavior, making automatic adjustments to stabilize ash levels, reduce white water consistency variability and minimize chemical and filler dosages.

This results in improved machine runnability by helping to reduce sheet breaks, and accelerating grade changes and break recovery. Papermakers can then track performance from the wet end to the final sheet. It is available as a subscription-based service delivered via ABB Ability™ Collaborative Operations, with structured remote monitoring and expert analysis of control performance for sustainable results.

In addition to its impact on productivity, Wet End Control helps to minimize raw material, chemical costs and broke usage, ultimately reducing the environmental impact and leading to lower steam consumption and increased energy savings.

“We know that continuous monitoring of wet end operations is crucial to driving process improvements,” said Ramesh Satini, global product manager for Pulp & Paper Control Systems, ABB. “We developed our Wet End Control solution to address this need by automatically managing targets and implementing cost efficiencies within process constraints. By adopting this ABB service, mills will benefit from ongoing insight and collaboration to optimize stability for long-term gains and minimized operator interventions.”

Wet End Control is part of a fully integrated quality measurement, control and optimization solution that works seamlessly with ABB Ability 800xA control system or a third-party alternative (via OPC interface). ABB’s latest APC platform allows dynamic model adaption to capture varying process dynamics for tighter control, while optimally working within operational parameters to maximize the economic gain. The solution is suitable for all mills seeking a quality measurement, control and optimization solution that enables paper specifications to be met at the lowest possible cost.

International technology group ANDRITZ is now offering its newly developed ANDRITZ pump controller (APC) – a flexible and individual control unit for interconnected pumps in sprinkler, wastewater, lifting, pressure boosting and fire extinguishing systems and in water supply networks.

The APC features excellent flexibility, enabling customers to set it themselves via an intuitive configuration interface to suit the individual circumstances in the plant, quickly and without requiring specialized personnel. Operating modes and available sensors can be integrated into the system with just a few clicks. Freely adjustable control parameters also provide automatic and optimum adjustment to plant conditions, thus making a substantial contribution towards maintaining high operating reliability and thus also to optimizing the process. The APC also provides optimum duty by the pumps integrated into the system, ensuring that the plant operates efficiently and with the longest possible service life.

The unit can be extended at any time by adding more pumps and functions, such as a remote monitoring concept or a connection to existing higher-level systems. By using a secure, remote interface – for example via mobile devices like tablets or smartphones – the operator can access the APC at any time and from anywhere in the world. Remote support and various updates implemented by ANDRITZ staff can also be added to these IIoT functions at the customer’s request. In addition, the APC expansion package includes modules to monitor vibration and energy consumption, connections to various bus systems, as well as taking account of additional digital and analog input/output signals for connection to higher-level systems.

In the standard design, the APC provides various functions like display, operation, notification, and control in accordance with the pre-defined control variables (pressure, head and flow rate) for up to six pumps. The control system switches the pumps on and off, replaces pumps for optimum distribution of use between the pumps, changes pumps over in the event of a fault, as well as providing the necessary protection functions like dry running protection, flow monitoring and anti-jamming. All of these functions are performed automatically.

Top class shoe press belts have a name: Yamabelt. In terms of lifetime and dewatering capability the belts have been setting benchmark standards for many years. With Aikido Yamabelt has once again come up with improved characteristics and reduced tendency towards crack formation.

When German engineering skills and Japanese inventive ingenuity come together the result cannot fail to impress. In this case, profound knowledge and understanding of the efficient dewatering of press felts meets decades of experience in coating and finishing of roll covers and shoe press belts. This is demonstrated in particular in the case of Yamabelt, which has been continually refined since 2010 as a result of close collaboration between Yamauchi and Heimbach.

Yamabelt has always been characterised by maintaining a high level of void volume while exhibiting a low risk of cracking. The belt consists of a two-ply coating, which allows it to respond to the different demands of both the smooth (shoe facing) as well as the grooved (felt facing) sides.

The void volume of Yamabelt must be able to withstand the line load in the nip and remain at a constant level throughout its life. Long service life in particular can lead to reduced void volume due to absorption of process chemicals. The stronger the line loads the more adversely affected the dimensional stability of the grooves in the nip can be. These effects can reinforce each other and negatively affect dewatering performance.

A powerful duo: Yamabelt Kendo and Yamabelt Judo
In early 2015 the successful collaboration between Heimbach and Yamamauchi led to an extension of the product range courtesy of the two designs, Kendo and Judo.

Kendo has been successful in ensuring the further improvement of void volume preservation. Its robust groove design prevents crack formation and propogation. The consistent high void volume over the entire lifetime of the belt is very significant.

To complement Kendo we offer the Judo belt for positions that tend to crack in the area of the shoe edges. Its polyurethane is extremely flexible and therefore able to withstand the highest demands.

Even more resilient: The new Yamabelt Aikido
The latest result of longstanding intensive research between Heimbach and Yamauchi is Aikido. In this case the proven characteristics of Judo / Kendo were combined and enhanced by a newly developed polyurethane formulation. This design specifically meets continually rising demands in terms of mechanical load capacity (line loads of currently up to 1400 kN/m).
