Lime is indispensable in the pulp and paper industry for its roles in alkaline pulping, chemical recovery, water treatment, and paper coating. Its use improves process efficiency, enhances paper quality, and supports environmental sustainability through effective resource utilization and wastewater management.
Market Needs
In the pulping process, lime is essential for regenerating chemicals used in the pulping method. It is used where it reacts with green liquor (sodium carbonate) to produce white liquor (sodium hydroxide). This white liquor is then reused to break down wood chips into pulp, making lime crucial for recycling chemicals and maintaining the efficiency and sustainability of the pulping process.
Solution
In pulp production, High-calcium lime is favored for its reactivity and efficiency in this stage, while dolomitic lime provides additional benefits in certain applications. Hydrated lime is used when a slurry form is needed. These types of lime are selected based on their specific properties to optimize chemical recovery and ensure effective pulp production.
