Delivery's technical information

Valmet Recovery Liquor Analyzer (Valmet Alkali R) measures green and white liquor chemistry according to laboratory standard. In addition to causticizing measurements and basis for optimization solutions, the analyzer provides tools to improve recovery boiler reduction performance with an online reduction degree measurement.

Based on the accurate measurements of the analyzer, Valmet Causticizing Optimizer maximizes green and white liquor concentrations, while eliminating scaling in the green liquor system and overliming in the causticizing process. Optimization leads to a high and stable quality of the white liquor, a higher production capacity, as well as reduced production costs at the causticizing plant and entire pulp mill.
