Transcribed Image Text:All % compositions in the following problem are by mass, unless otherwise noted.
The flow-sheet of the downstream section of a metal processing facility is shown in
the Figure below. It has two waste streams:
Stream 1 has 23% Iron Oxide (ferric oxide) in water.
• Stream 2 flows at 120 kg/hr has 14% by mole Magnesium Oxide in water.
The two streams are combined and then passed through a filter that removes most
of the solids. It is known that:
• 89% of the iron oxide entering the process is removed through stream 4.
• 90% of the magnesium oxide entering the process is removed through stream
4.
• Stream 4 has 38% magnesium oxide in it.
• Beside iron oxide and magnesium oxide, stream 4 also has some water in it
(carried away with the filtered solids.)
• Stream 5 contains mostly water and some iron oxide and magnesium oxide
left over in it. It has 2.1% of magnesium oxide in it.
Calculate the mass flow rate and composition (mass fractions) of all streams of the
process.
