A spherical tank of diameter of 10 meters contains liquid toluene at 1 atmosphere at 25 oC. An initially filled tank is drained from the bottom such that the liquid level drops to half. As we drain the tank, toluene vaporizes. The enthalpy of vaporization of toluene at its normal boiling point, Tn =383.8 K, is 33.74 kJ/mol. Calculate the number of moles toluene evaporated from liquid to vapor phase. If the draining is isothermal, calculate the amount of heat provided by the atmosphere to the toluene in the tank.

The exit stream of a beer fermentation system (F) contains ethanol, water and fermentation solids and has a mass flow of 1200 ton/day. This stream is fed to a separator from which has to outlets: a stream of 300 ton/day of solids (S) and a stream (A) that is fed to a distillation column. From the top of the column, a flow of 750 ton/day of beer containing 12.5% ethanol and the balance of water is released; the bottom flow contains water with 1% of solids. The beer contains 96% of the ethanol fed to the process.
a) Draw a process diagram.
b) What is the composition of stream F, in mass percentages?
c) Find the mass flow in kg/h and composition the stream (A) entering the distillation column.

A sweet, water-saturated natural gas enters a compressor at 50 psia and 100F and leaves at 200 psia and 300F.
a. Is there any chance of water condensing in the compressor? If so, how much? Answer in lb H2O/MMscf gas compressed.
b. Estimate the mole fraction of water vapor in the gas stream leaving the compressor.
c. The natural gas is then cooled to 190 psia and 100F before entering the second stge of compression. Should a vapor-liquid scrubber be installed between the intercooler and the second stage of compression? If so, how much water (lb H2O/MMscf) will be removed? Will any hydrocarbon liquids condense?
