Valmet Celebrates 50th Kappa Analyzer Startup in South America

 

The 50th Valmet Kappa Analyzer in South America has successfully started up at the CMPC Guaíba pulp mill in Rio Grande do Sul state, south of Brazil. Installed in the mill's second fiber line, a greenfield project supplied by Valmet, the Kappa Q analyzer measures Kappa and brightness from 6 points, starting at the blow line through to bleaching. 

 

 

According to Andrea R. S. Busnello (photo), Fiber Line Process engineer, "The Kappa Q analyzer provides us with fast and reliable information. Based on the analyzer measurements, it is possible to get a better process understanding, calculate the right amount of chemical, reduce the raw material variation impact, and it also helps to achieve the final pulp quality."

The Valmet Kappa Q utilizes patented sweep technology to measure kappa and brightness with a unique two-point calibration method. Capable of measuring critical properties - lignin content, brightness, pulp fiber and shives, the analyzer is easily expanded according to measurement needs and the number of sampling points. 

CMPC Celulose Riograndense Ltda is part of the Chilean group, CMPC, one of the largest forestry-based companies in Latin America. Its mills in Chile and Brazil produce around 4.3 million metric tpy of pulp (hardwood and softwood).
