Recaust Liquor Testing
Online Course Description:
The kraft chemical pulping process produces strong pulp because of the special characteristics of the cooking liquor. The presence of sodium sulfide (Na2S) in combination with the sodium hydroxide (NaOH) in the cooking liquor, protects the pulp fibers from degradation during the cooking process. The control of the chemical composition of the cooking liquor is critical for production of strong pulp fibers. The liquor testing in the recausticizing process provides critical information for that control. This module provides information about the liquor testing in the recausticizing process, what those test results mean, and why it is important to the processes involved.
