Abstract
The flow curves of bagasse Kraft black liquor over a shear-rate range of 10-1s-l～103s-1 were investigated by using the Rheometric RFSⅡ rheometer.Experimental results show that Bagasse black liquors are non-Newtonian fluids instead of Newtonian fluids at higher solids contents, and the viscosities of black liquor would decrease .about 2～3 orders of magnitude with an increase in the shear rates. The apparent viscosity and flow behavior of bagasse black liquor are also affected by its solids content, and the higher solids content the more shear-thinning bagasse black liquor fluid is. In addition, the power-law equation was utilized to fit these flow curves at different conditions. Finally, the significances of shear-thinning properties of bagasse black liquor in the chemical recovery system, such as friction calculation of pipe and design optimization of the whole recovery system, were presented.关键词
