Photochemical reactor modeling: a case-study problem. Although radiation is important in heat transfer, an analogous model can be used in the design of photochemical reactors. The modeling of these reactors….
Determine the specific gravity (S s) of the dry solids in the slurry.
The water content of a solids slurry is reduced from 99% to 96% by gravity thickening. Assume that the dry solids contain 20% organic matter with a specific gravity of 1.0 and 80% inorganic or mineral matter with a specific gravity of 2.0. Lime sludge thickens to 5.0% solids in a gravity thickener. Assume that 25% of these solids are volatile and that the specific gravity of the fixed and volatile fractions in the solids is 2.5 and 1.0, respectively. Determine:
a. The specific gravity (S s) of the dry solids in the slurry.
b. The specific gravity (Ss1) of the 99% solids slurry.
c. The specific gravity (Ss1) of the 96% solids slurry.
d. The percent reduction in volume when the water content is reduced from 99% to 96%.
