Reliable Sampling &Sample HandlingYears and years of continuous operation have proven thereliability of the Kajaani sampling technologies. Metal-to-metal construction, robust design and no gaskets of thePiston/Cylinder ensure that the samplers can operate re-liably with a year’s minimum service period.

Sampler type is selected accord-ing to the application and processconditions in the sampling point,e.g. pressure and consistency.Manual spot samples can also beanalyzed. In addition, an optionallaboratory sample collector maybe included in the system. Thisdevice collects a representativesample for parallel lab analyses

from each sampler installation point. Sample collection ispart of pulp mills’ ISO 9000/14000 program.

The sampling devices are mounted to the process pipe-line. The device extracts pulp samples, dilutes them withwater, and delivers them to the analyzer’s washing unit.

Efficient and Repeatable SampleWashing Reveals Pulp QualityThe analyzer’s operating sequence begins with samplingfrom the process. The sample is transported to the wash-ing unit where the excess process and transport water aredrained off. The sample is then washed with warm andcold water, mixed thoroughlywith pressurized air, and itsinitial consistency is mea-sured at a constant volume.After this the sample process-ing method is dependent onthe selected measurements.Measuring sequences can beconfigured separately foreach sampling point.

When the measuring sequence is over, the analyzer iswashed and calibrated automatically by means of watermeasurement.

If the analyzer has one washing unit, the operating se-quence is repeated as such for each sample. With twowashing units, their sequences overlap partially so that anew result is available every 31/

2 minutes.

Proven Reliability, Speed and Accuracy

True Modularity for Widest Applicability

EOP Kappa#

Final Brightnesskajaani KAPPAi and BRITEi analyzersapplicable to the entire fiber line.

Gives You FlexibilityThe experience we have gained from over a hun-dred analyzer installations together with the newfeatures and design of kajaaniKAPPAi andkajaaniBRITEi analyzers, assure the efficient controlto cover the whole fiber line. Our digester applica-tions with kajaaniKAPPAi meet most of Kappa mea-surement needs, such as high yield, continuous mid-point, batch and continuous blow pulp. On-lineKappa measurements at Oxygen delignification,from front of the bleaching till EOP Kappa are todaymill standards. The absolute brightness measure-ment is becoming more and more common inmodern mills. Our new solution to applykajaaniBRITEi to absolute brightness control and fi-nal pulp quality control finalizes the bleaching con-trol success.

All the analyzers’ technological features have been inte-grated in a way that expandability is possible without ma-jor equipment changes but more or less with plug andplay field retrofit additions. Sampling devices, sample treat-ment units and new measurements can be added to the

system later on. This assures that our customer will ben-efit from all the latest development changes in his fiberline, with the same platform of the analyzer.

KajaaniKAPPAi and kajaaniBRITEi are modular twins with

compatible components and features; they demonstrate

true modularity for the widest applicability.

Unsurpassed Accuracy withthe Sweep MeasurementThe latest invention to meet the currentcontrol needs of Kappa and Brightnessmeasurement is our unique Sweep Mea-surement (pat. pend.) which measures theoptical response of the measured sub-stance over a range of consistency swing.Together with the pressurized measure-ment technology, the sweep method cre-ates high accuracy of Kappa and Brightnessand is substantially faster than our previoustechnology. Thanks to this unique method, analyzer giveslinear response to Kappa and Brightness. The traditional

The unique Sweeptechnology measure-ment based on thecontinuous optical re-sponse curve.

linear two point calibration can be applied, which makessystem commissioning easier and faster.

Kappa number is measured optically. While a sampleflows through a measuring cell, Xenon light is directedthrough it and the light scattering is measured at differ-ent wavelengths.

Pulp brightness is measured in an optical cell where thelight reflectance and scattering properties of pulp fibersare measured by means of Xenon light. The analyzer alsomeasures the flocculation index of the pulp for hardwood/softwood detection.

An additional benefit of the new measurement tech-nology is the simpler measurement sequence which re-duces the load on the sample treatment system. The sys-tem maintenance need has also been reduced apprecia-bly due to fewer sequence cycles.

Advanced Self-DiagnosticsThe analyzer’s self-diagnostics constantly monitors and

tunes the system operation and analyzes the accept-

ability of the obtained results.

At preprogrammed intervals the analyzer performs a

self-test, checking the operation of valves, flow rates,

and level sensors. If an error is detected, the system

alerts the operators and gives a report that specifies the

necessary service action and the order code of any spare

parts that may be required.

Long-term PerformanceAssuredCalibration StandardThe kajaaniKAPPAi and kajaaniBRITEi analyzers have a

simple, two-step guiding procedure which allows the op-

erators to check the measurement accuracy and calibra-

tion at any time. In addition, this procedure can be used

after service operations to return the system to the origi-

nal calibration if needed.

There’s no need to sweat over maintenance – self-diagnostics runs in the background watching over every action. Regularchecking and routine preventive maintenance ensure high reliability. When needed, Metso Automation’s service is alwayswithin reach by phone or modem to provide in-depth support.

The key to the success

of effective fiber line operation and

total product quality is more than ever depending

on continuous information provided by on-line

analyzers and measurements. Our 30-year-long

history in creating innovative new ways to

measure and control processes has proven to be

an ongoing success. Today 80 % of the world’s

fiber lines are benefiting from our solutions for

bleaching process control. Still today, the Kajaani

sensors and analyzers are the cornerstones of

control solutions that assure cost effective

pulp production with the least

environmental impact.
