Q2: A stream of liquid water at a rate of N lit/s with a stream of methanol and
ethanol mixture (contains 25 mol% methanol) are fed to continues evaporator.
Another stream of methanol at a molar flow rate of G that of the alcohol mixture
stream is fed to the same unit. If the liquids are evaporated totally and the produced
vapor stream contains (0.1"G) mol% of water at a pressure of 28 psi and 220 F.
calculate:
1- The flow rate and composition of all streams in a molar, mass, and volumetric
basis
2- The average molecular mass of all streams
The Specific gravity of methanol is 0.762 and that of ethanol is 0.789 while the density
of vapors can be estimated as: p= p*Mw/RT where R-0.082 atm.m'/kmol.K.

8. 9. butane is consumed, and the product gas contains 9 mol CO2 per mol CO. Calculate the molar flow rate of water in the stack gas. Butane is completely burned in a process fed with 25.0% excess air. Based on 1 mol/h of butane, determine the composition in mole fractions of oxygen in product stream. Methane at a molar flow rate of 55 mol/min is burned with dry air. A partial analysis of the exit gas reveals that the mole fraction of nitrogen is 0.85 on a dry basis, and the molar flow rate of the dry exit gas is 600 mol/min. P
1. A wet gas from a field in Iran is processed through two stages of separation; first stage separator operates at 220 psia and 71°F, while the stock tank operates at atmospheric pressure and 69°F. The separator gas condensate ratio is 41,000 scf/STB and the stock tank gas condensate ratio is 450 scf/STB. The molecular weights of the separator gas and stock tank gas are 25.0 and 35.0 lb/lb-mol, respectively. The stock tank condensate gravity is 0.85 and its molecular weight is 125 lb/lb-mol. Let us calculate the specific gravity of the reservoir gas in a step-wise manner, by considering quantities for one STB of condensate. Note that 1.0 bbl is 5.614 ft.
