Mass and energy balances over the lime kiln in a kraft pulp mill

The potential to recover energy from the hot lime kiln flue gases using better lime mud filters and an external flash dryer was studied in the second set of simulations. By using this constellation the high-value energy of the flue gases could be used for steam generation instead of being used for drying.

Land Application of Pulp Mill Lime Mud - UGA

What Is Lime Mud? Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate.
