Lime Kilns in stone Kraft Recovery - Convergence Pulp ...
The most common lime kiln designed found at kraft pulp mills is the rotary lime kiln. A rotary lime kiln is basically a long tube or cylinder set at a slight incline that slowly rotates. Lime mud is continuously fed in at the higher end of the cylinder, and the rotation and incline of the kiln cause the mud to slowly move down toward the opposite end.
2-2 Lime Kiln Principles And Operations
Rotary lime kilns in the pulp and stone industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by 400 ft (122 m) long. The refractory lining is from 6 in. (15.2 cm) to 10 in. (25.4 cm) thick.
Lime kiln - ANDRITZ
The lime kiln is a huge consumer of energy in a pulp mill, and a large potential generator of CO 2 emissions. Energy and emissions need to be adequately controlled to consistently produce high-quality lime for cooking liquors. Well-proven lime kiln technology with integrated auxiliaries
Pulp mill lime kilns go fossil free - Valmet
In a modern pulp mill, the lime kiln is the only major consumer of fossil fuel – usually natural gas or fuel oil. During the oil crisis in the 1970s and 1980s, several alternatives to fossil fuel were developed to reduce operational costs.
Special Cantilever Lime Mud Screw Conveyor
End user needed a solution for conveying very wet lime mud into a rotary kiln at a pulp mill. Lime mud is a by-product of the stone process for making white liquor. White liquor is used in the digesting process for converting stone chips to stone pulp. The lime mud is calcined in the rotary kiln at very high temperatures and converted to lime.
Lime in Pulp and stone Mills | Graymont
Lime is used in several applications within pulp mills. One of the most common applications is for the sulfite-pulping process. This process uses acid to dissolve the glue (lignin) that holds the fibers (cellulose) together.

2-3 Lime Kiln Chemistry & Effects on Operations
A lime kiln is used to convert lime mud into lime for reuse in the causticizing plant of the kraft recovery process. Many of the problems encountered in lime kiln operations can be related to kiln chemistry, including TRS and SO2 emissions, dusting, ringing and refractory stone thinning. Understanding the composition and thermal behaviour of

Mass and energy balances over the lime kiln in a kraft ...
The purpose of this thesis is to create a model of the lime kiln that performs mass- and energy balances over the process. This model is to be integrated in the WinGEMS software that is used to simulate mill systems in the pulping industry. There is an existing lime kiln block in WinGEMS but since has proven inadequate and in need of replacement.

Lime Kiln - an overview | ScienceDirect Topics
Extractives such as rosin and fatty acids are sometimes removed from the spent pulping liquor and processed into crude tall oil. In Canada, most crude tall oil is currently incinerated as fuel in the lime kilns of pulp mills to displace fossil fuel. In the south eastern United States, where extractive content of the stone is much higher, tall oil plants fractionate the crude tall oil into value-added components.
