Add-on to fiber analyzers provides a complete range of fiber measurements, both image-based and non-image based, from one laboratory pulp sample for a truly holistic view of pulp fiber properties.

ABB has launched the first laboratory fiber analyzer that has the capability to accurately detect the amount of crill in any pulp mixture. L&W Crill is an optional module to the portfolio of ABB’s fiber analyzers. It uses a method based on the fact that small particles absorb and scatter light, which makes it possible to detect very small particles in a pulp suspension. It expands ABB’s offering of Lorentzen & Wettre products for fiber testing.

L&W Fiber Tester Plus – now available with L&W Crill, the option to measure crill

Crill is an important variable to measure in pulp mixtures, as these tiny fibers contribute to overall paper strength and end product quality.

ABB’s popular L&W Fiber Tester and L&W Fiber Tester Plus laboratory fiber analyzers are based on image analysis – there are more than 175 units installed worldwide. The addition of L&W Crill adds another dimension to pulp analysis and makes it possible to measure a new property.

L&W Crill analyzes pulp suspensions to monitor refining and dewatering. Refining the pulp increases the L&W Crill quota. During the refining process, the fibers are affected in different ways. For example, the fibrils of the fiber walls are exposed to a certain degree; these fibrillary particles on the fiber wall are described by crill. With this added capability, the L&W Fiber Tester Plus can now provide all information needed to understand pulp composition, including fiber length, fiber width, shape factor, fines content, fibril index and crill.

Because L&W Crill is not based on image analysis, it is not limited by the resolution of an imaging system. Instead, L&W Crill analyzes how particles with different diameters absorb and scatter light of different wave lengths. By sending UV-light and IR-light through a pulp suspension, it detects if small particles are present in the solution.

”We can now offer a complete range of fiber measurements methods within the same laboratory equipment, so you can get a truly holistic view of your fibers from analyzing only one sample,” says Anna Schärman, Global Product Manager, ABB AB/Lorentzen & Wettre products.

ABB (http://www.abb.com) is a leading global technology company in power and automation that enables utility, industry, and transport & infrastructure customers to improve their performance while lowering environ-mental impact. The ABB Group of companies operates in roughly 100 countries and employs about 135,000 people.

Lorentzen & Wettre, and ABB Company, have announced a new FSD (Forming Section Drainage) Sensor for paper and board machines. This new sensor measures the amount of water at any desired position in the forming section. The measurement results make it possible to gain control of drainage and ply bonding.

With L&W FSD Sensor it is possible to optimize the wet end chemistry of the stock, which will enable better runnability and increase paper quality.

Normal use is in single point measurements between step foils or vacuum boxes. It is common to measure before or after the couch roll, to be able to estimate moisture content in the paper, before it leaves the wire. In multi-layer Fourdrinier machines all layers are easily monitored, providing a better overall picture to improve multiple ply bonding. The instrument provides for control of foils adjustments, vacuum, refining and the use of retention chemicals.

The main advantages of controlling drainage is reduced energy consumption, reduced number of web breaks, reduced emissions, reduced usage of chemicals and reduced wear and maintenance. These are benefits that lead to lower costs, better runnability and increased paper quality. Further L&W FSD Sensor uses high frequency technology instead of radioactivity and therefore requires no special permit to be used.

“With this new sensor in combination with our other portable instruments, it is possible to monitor the drainage profile all the way from headbox to couch”, says Mr Lars Kånge, Product Manager, Lorentzen & Wettre.
