Abstract
A high solids black liquor which has solids content of at least 65% by weight of liquor is mixed with a viscosity reducing additive prior to firing in a chemical recovery furnace. The additive is an admixed compound consisting of monoethylene glycol, diethylene glycol and triethylene glycol.
Claims10
A high solids content black liquor having the property of a reduced viscosity relative to an initial Brookfield viscosity rating of 1150 CPs comprising:
- a solids content of at least 50% by weight of liquor and a viscosity reducing additive comprising an admixed compound of monoethylene glycol, diethylene glycol, and triethylene glycol.
A method for reducing the viscosity of a high solids content black liquor comprising the step of treating the black liquor with a viscosity reducing additive comprising an admixed compound of monoethylene glycol, diethylene glycol, and triethylene glycol by mixing about 0.01 to 10% by weight of said additive with said black liquor.
