Question

A binary mixture of benzene(1) and toluene(2) is flashed to 75kPa and 90°C. Analysis of the effluent liquid and vapor streams from the separator yields: x1 = 0.1604 and y1 = 0.2919.

An operator remarks that the product streams are “off-spec” and hence might affect the final application of the binary mixture. You are asked to diagnose the problem.

a) Verify that the exiting streams are not in binary equilibrium

b) Verify that an air leak into the separator could be the cause.
