Valmet celebrates the 50th Kappa Analyzer start up in South America

The 50th Valmet Kappa Analyzer in South America was successfully started up in May 2015 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, 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 produces around 4.3 million tonnes of pulp per year (Hardwood and Softwood).
