The washing process shown in Figure 1 has been operating for an extended period of time and no
parameter is changing significantly over time. The washing process was set up to take the Raw Pigment
and remove as much of the undesired salt from the desired TiO2 as possible, so that the salt can be
disposed of in the Waste Water stream, leaving the valuable TiO2 in the Washed Products stream. If the
process is running with a yield of 85% TiO2 and a selectivity of 7 in Stream B, then calculate the amount
of water leaving in the Waste Water Stream (i.e. × ) in kg/h to 7 significant figures.
For this question, include: Given, Find, Assumptions, Analysis, and Conclusions. Also include full balances
using the General Balance Equation, where necessary.
