Analyses for Cellulose Pulp
In pulp mills, it is of utmost importance to consider many different parameters to ensure both efficient operations and high quality of the produced pulp. One of the most crucial factors is the raw material used, namely wood.
Optimization of Pulp Production Through Analyses
The quality and composition of wood directly affect the end product, and a stable supply of high-quality wood is crucial for production.
The chemical environment in the production process is also important, as it influences the fibres from cooking to bleaching and the formation of the pulp. Properly balanced chemicals and process parameters are essential for maintaining the integrity of the fibres and avoiding quality issues.
By closely monitoring these parameters, pulp mills can ensure a consistent production of high-quality pulp, which is important for meeting market demands and maintaining competitiveness. Continuous optimisation of the process is vital for efficiency and sustainability within the pulp industry.
RISE addresses pulp quality through analyses of key properties and fibre dimensions to ensure good runnability and product quality.
Fiber Properties and Chemical Analyses
To ensure high-quality pulp production, thorough analyses of fibre and pulp are essential. The analyses include:
- Malgrad SR/CSF: Measures the pulp's grindability.
- Water Retention Value (WRV): Assesses the pulp's ability to retain water.
- Fibre Dimensions: Includes the length, width, and distribution of fibres.
- Fibre Content: Indicates the amount of fibres in the pulp.
- Fines Content: Measures the proportion of fine particles.
- Sheet Formation: Assesses the pulp's ability to form sheets.
- Basis Weight: Indicates the density of the pulp.
- Thickness and Density/Bulk: Provides information about the pulp's structure.
- Tensile Strength: Measures the pulp's strength.
- Burst Strength: Indicates resistance to deformation.
- Tear Strength: Assesses the pulp's wear resistance.
- Air Permeability: Measures the pulp's ability to allow airflow.
Chemical analyses are also important and include:
- Carbohydrates: Measures the amount of carbohydrates.
- Cellulose: Separation of different types of cellulose.
- Extractives Content: Measures the amount of extractable substances.
- Phenolic Groups: Assesses chemical reactivity.
- Fibre Charge: Measures the charge on the fibres.
- Water Absorption Capacity: Measures absorption ability.
- Metals: Measures the amount of metals in the pulp.
- Viscosity: Indicates the pulp's flow properties.
- Washing COD/TOC: Measures organic compounds and carbon.
Through these analyses, insights into the properties of the pulp are gained, which is crucial for optimising production and ensuring that it meets requirements and specifications.
