Manufacturing Process

This report comprises a thorough value chain evaluation for Sodium Lignosulfonate manufacturing and consists of an in-depth production cost analysis revolving around industrial Sodium Lignosulfonate manufacturing.

• Production via Sulfite Pulping and Neutralisation: The feedstock for this process includes softwoods (such as pine or spruce), water, sulfite chemicals (e.g., sodium bisulfite or sulfur dioxide), and sodium hydroxide (NaOH). The process of making sodium lignosulfonate starts with softwoods like pine or spruce. These woods are first turned into small chips, which are then soaked in a mix of water and sulfite. This soaking helps break down the lignin, a natural component in the wood, and creates a liquid called spent liquor that holds lignosulfonates. After that, sodium hydroxide is added to this liquid, which helps turn it into sodium lignosulfonate. Finally, the mixture is filtered to remove any leftover solids, cleaned up to get rid of impurities, and then dried by spray drying to obtain pure sodium lignosulfonate as the final product.
   

Properties of Sodium Lignosulfonate

Sodium Lignosulfonate (SLS) is an amorphous polyelectrolyte derived from lignin, which is known for its complex polymeric structure and diverse functionalities.
 

Physical Properties

• Appearance: Yellowish-brown to dark brown powder or granular solid. It can also be a dark brown viscous liquid.
• Odour: Odourless or with a faint sulfury smell.
• Molecular Formula: No single exact molecular formula due to its polymeric and heterogeneous nature. It is a complex mixture of lignosulfonate macromolecules. A common approximate average formula is C20H24Na2O10S2.
• Molar Mass: It varies widely, as it is a polymer. Average molecular weight ranges from 1,000g/mol to 100,000g/mol or higher, depending on the pulping process and purification. The average is often quoted around 10,000g/mol.
• Melting Point: No sharp melting point; it is an amorphous polymer that chars or decomposes at high temperatures. Decomposition generally begins above 200 degree Celsius.
• Boiling Point: Not applicable, as it is a solid polymer that decomposes before boiling.
• Density:
  • Solid (powder): Approximately 0.4−0.7g/cm3 (bulk density, varies by grade and particle size).
  • Liquid (solution): Approximately 1.2−1.3g/cm3 (for concentrated solutions).

• Hygroscopicity: Moderately hygroscopic, it can absorb moisture from the air, especially in powdered form.
• Flash Point: Not readily applicable for the solid powder as it is combustible but not highly flammable. Flash point for liquid solutions would be above 100 degree Celsius due to water content. Autoignition temperature for similar lignin compounds can be around 400 degree Celsius.
   

Chemical Properties

• Dispersant/Surfactant: Due to the presence of both hydrophilic sulfonate groups and hydrophobic lignin backbone, it acts as an effective anionic dispersant and surfactant. It reduces interfacial tension and prevents the agglomeration of particles in suspensions.
• Binding/Adhesive Properties: Its polymeric structure allows it to act as a binder, holding particulate matter together, as seen in animal feed pellets, foundry sand, and road dust control.
• Chelating Agent: The sulfonate and phenolic hydroxyl groups enable it to chelate (complex) with various metal ions, which is useful in stabilising metal ions in solution or preventing their precipitation (e.g., in water reducers, dispersants).
• Redox Properties: Lignin itself has some phenolic hydroxyl groups that can exhibit antioxidant properties, contributing to the overall stability in some applications.
• pH Stability: Solutions are generally stable over a wide pH range, though their behaviour as a dispersant can be pH-dependent. Commercial products often have a pH range of 4.0-10.0.
• Thermal Stability: It is generally stable at normal temperatures. It can decompose at high temperatures.
• Biodegradability: It is derived from natural lignin, and it is considered environmentally friendly and generally biodegradable. The exact rate of biodegradation can vary depending on its molecular weight and degree of sulfonation.
• Non-corrosive: It is non-corrosive to steel and other common materials, which makes it suitable for use in concrete admixtures and other industrial formulations where corrosion is a concern.
