Recausticizing - A complete concept
The recausticizing (causticizing) stage completes the chemical recovery cycle converting green liquor to white liquor. In this process most of the Na2CO3 in the green liquor is turned back into NaOH in white liquor, which can then be used for cooking liquor. The aim of the process is to produce as much strong white liquor as possible.
The main parts of the concept are:
- Green liquor handling
- Cooling, slaking and causticizing
- White liquor handling
- Lime mud handling
