Hydrocyclones
Many units, such as hydrocyclones and gravity separators, produce a degree of size separation and the particle size data can be used for mass balancing (Example 3.15). Example 3.15 is an example of node imbalance minimization; it provides, for example, the initial value for the generalized least squares minimization.

Wet flue-gas desulfurization (FGD) systems generally operate in a pH of 5.0 or above and require feed of reagent to remove sulfur. Limestone slurry is the most commonly used reagent. The quantity of slurry depends mostly on the sulfur levels in the coal. It is common for modern FGD systems to achieve 99 percent removal of SO 2.

Hydrocyclone Working Principle
The Volume of slurry that is being fed into the cyclone must not exceed the capacity of these two outlets that allow it to escape. The size of the apex and the vortex finder is crucial. If the apex of the cyclone, like the size of the drain in your sink, is made smaller it won't allow as much slurry out of the underflow of the cyclone.
