Green liquor and lime are combined in the slaker, and then transferred to a series of vessels called causticizers. The result of this process is a slurry of white liquor and lime mud. In order to be used in the digesters to break down wood chips, the white liquor must be separated from the lime mud. The first step in this process is to purify the white liquor by allowing the mud to settle in a sedimentation clarifier. This course will identify and describe the major components of a white liquor clarifier.

At the end of this module, you will be able to:

  • Identify and describe the major components of a white liquor clarifier
  • Describe the purpose and operation of a white liquor clarifier
  • Identify and describe the typical process flows in a white liquor clarifier
  • Identify key safety considerations when working around a white liquor clarifier

The following key questions are answered in this module:

How is white liquor created?
White liquor and lime mud are the result of the slaking and causticizing reactions which occur upstream of the white liquor clarifier.

What is the primary purpose of a white liquor clarifier?
The primary purpose of a white liquor clarifier is to provide a place for suspended lime mud in white liquor to settle to the bottom of a clarifier tank.

How is lime mud removed from a white liquor clarifier?
Lime mud settles to the bottom of a clarifier and is plowed by a slowly rotating rake to the middle of the tank. The mud is then pumped away.

What can happen if lime mud is not effectively separated from the white liquor?
Excessive downstream lime mud can lead to scaling in digesters and evaporators.

How is clarifier white liquor removed from a clarifier?
Liquor is collected from multiple points in a header around the circumference of the clarifier. The header can be inside or outside of the clarifier.

Below is a transcript of the video sample provided for this module:

A sedimentation clarifier is a tank or basin that provides the time necessary for suspended solids in a liquid to settle out. The major components include, the raw liquor inlet, center feedwell, settled material outlet, bustle pipe/ring header, clarified liquor outlet, rake, and the drive motor for the rake.
