White Liquor ABC Test
"Self-guided, blended learning testing labs examining property measurements and variables."
Knowledge of the composition of Kraft pulping liquor is vital for pulping operations and pulp quality. The three primary chemicals present are sodium hydroxide (NaOH), sodium sulfide (Na2S), and sodium carbonate (Na2CO3). Other chemicals like sodium sulfate (Na2SO4) and sodium sulfite (Na2SO) are also present in smaller quantities. We will analyze for the three primary liquor components using the ABC test.
Scope and Learning Objectives:
These self guided testing labs and video modules demonstrate the procedures used to test chips, pulping & bleach liquors and pulp. They will also provide some background about the property being tested. The overall learning objective is to increase your understanding of why and how these tests and procedures are performed.
The outline you should follow for each lab is to learn the background information on the property being tested, note the TAPPI Standard (T264, Preparation of wood for chemical analysis), then view the video on the correct testing procedure. Sample data is provided. Some of the labs will require calculations and analysis of data, and other labs will provide final data without calculations. A short set of thought questions is included at the end.
