This separation occurs on brown stock washers, where water is used to wash the black liquor from the pulp. At the end of this module, you will be able to describe the importance of countercurrent washing and identify the process variables that effect washing.
At the end of this module, you will be able to:
The following key questions are answered in this module:
Why is it important to remove black liquor from pulp after cooking?There are two reasons. 1) Cooked pulp could not be made into paper without removing the black liquor, and 2), the inorganic chemicals in the black liquor can be reused once they are separated.
What is the principle behind countercurrent washing?Countercurrent washing takes advantage of the fact the very dirty pulp can be washed with somewhat dirty liquor. This allows wash liquor to be reused multiple times.
What is the source of vacuum for most vacuum drum washers?The vacuum in most drum washers is derived from gravity pulling the filtrate removed from washer down a dropleg.
What are some of the factors which affect the performance of a drum washer?Some of the factors which affect washer performance are shower and stock temperature, shower flow and distribution, drum speed and vat consistency.
What are three different configurations of brown stock washers?Washer types include drum, belt, and diffusion washers.
