In the Recaust Kiln area the largest operating cost is the fuel required for the calcining reaction. To help improve the energy efficiency and keep up with production targets, McFarlen Engineering has worked with innovated chemical partners to help improve the performance of the lime mud pre-coat filter by improving drainage properties of the

In the Recaust Kiln area the largest operating costs is the makeup purchased lime required and the fuel required for the calcining reaction. The major driver of fuel consumption is the water content in the lime mud entering the Kiln. Reducing the water content in the lime mud is essential to lower operating costs and the requirement ofRead More
This tank is used to store thickened lime mud from the lime mud washer prior to filtration on the lime mud filter. Lime Mud Filter A vacuum precoat type filter washes and dewaters the lime mud prior to feeding into the lime kiln. Lime Kiln The lime kiln calcines the recovered lime mud into quicklime for use in the lime slakerRead More

Now that we have discussed the role of the recausticizing system in the kraft pulping process, we will detail the system equipment and operations, starting with the green liquor clarifier and ending at the lime kiln. The green liquor clarifier purifies the green liquor from the smelt dissolving tank before it enters the recaustRead More

Filtered lime mud at the Elk Falls mill had low solids content and was dark green. Along with high NPE dead load, this caused additional kiln fuel costs of nearly $300,000/year. An NPE mass balance was obtained, using composite samples from fifteen different process streams. Kiln fuel oil was a significant source of phosphorus, iron and zinc. NPE specifications for lime rock, fuel oil, saltRead More
temperatures, lime charge, time, and lime quality, on causticizing efficiency, mud settling and filtration. The effect of lime kiln operating variables on energy use and lime quality will be summarized, together with the state of the art in control systems for both the lime kiln and recaust operations. Trouble-shooting and problem-solvingRead More
