Black liquor analyzes
In the production of sulphate pulp, black liquor is formed as a residual product. It contains the consumed cooking chemicals and wood substances.
Purpose
Black liquor contains mainly lignin, hemicellulose, resins and fatty acids. RISE can measure ash content, fiber content, hydroxide, carbonate, carboxylic acids, chloride, carbohydrates, lignin, metals etc.
