Valmet introduces Valmet Brown Stock Analyzer for high yield and brown pulp

Valmet Oyj’s trade press release on June 7, 2023 at 9:30 a.m. EEST 

Valmet has developed Valmet Brown Stock Analyzer to complement its online pulp quality analyzer family. The analyzer provides high analysis frequency for digester and brown stock washing control in kraft pulping. It is the most robust Kappa measurement for high yield and brown pulp, designed to measure the coarsest pulp starting from cooking blow line.

“This is the only analyzer in the market with dual sampling points for blow line Kappa, before and after refining. Accurate and frequent Kappa profile ensures superior process control and enables the mill to optimize cooking parameters, resulting in better yield and pulp quality,” says Timo Laurila, Business Manager, Pulp and Energy Analyzers, Automation Systems, Valmet.

Technical information about Valmet Brown Stock Analyzer

Valmet Brown Stock Analyzer utilizes a well-proven sampling technology to extract a pulp sample and transport it to the analysis unit, where the dissolved lignin is thoroughly washed, and pulp Kappa number analyzed by an advanced optical measurement technology. The Kappa measurement range is 9–120.

The pulp sample handling principle minimizes water consumption, ensuring effective opera­tion even with high shive content pulps. A low number of moving and wearing parts minimizes the need for maintenance.

The user-friendly analyzer design keeps operators away from the harsh process environment, ensuring that laboratory sampling is carried out in a convenient and safe loca­tion with the automated built-in laboratory collector. Only the process sampling device is connected to the pressurized pulp process.
