Answer to Question #135238 in Atomic and Nuclear Physics for john

Question

A mixture of acetone and water are sent through a distillation column. In one stage of the distillation column, 286 kg/h of a mixture that is 30 mass percent acetone enters and is split into two streams, a liquid and vapor stream. The vapor stream contains 74 mass percent acetone, and the liquid stream contains 18 mass percent acetone.

What is the total flow rate of the liquid stream?

Answer 1

This material balance problem can be solved by table method.

0.18x + 0.79y = 85.8

x + y = 286

y = 56.26

x = 229.74

Answer: 229.74 kg/h
