| Abstract: | The boiling point rise (BPR) of black liquor with solids content of 85 to 98% was measured in superheated steam. The BPR for 85 and 95% solids content liquor is 28 and 52°C, respectively. A surprisingly large amount of liquor swelling occurs in this environment. A swelling mechanism is proposed. |
