| A technique has been proposed to calculate the efficiency of purification from suspended particles both in the
crystallizer and in the countercurrent crystallization column. The crystallizer has been shown to be the major contributor
to the purification from 40-350 nm radius suspended particles. Crystal grinding increases The separation factor,
which is achieved in an equivalent height countercurrent crystallization column, can be increased 2.2 times by
crystal grinding. The technique allows one to lower the particle content in purified benzene by more than three orders
of magnitude. |
