1) Calculating Number of Stages in Counter-Current Stripping with Tray Towers:

A counter current steam stripper has a liquid stream containing 0.02 mol % nitrobenzene in water. Entering steam is pure water. Outlet mole fraction of nitrobenzene in liquid is 0.00001. Assuming dilute species with constant liquid and gas flow rates. Equilibrium can be represented as Y = 28*X

(a) Calculate minimum vapor flow rate (V’min) to perform the operation, given L’ = 1000 kmol/hr.

(b) Given L’/V’ = 12; calculate the outlet mole fraction of nitrobenzene in the vapor stream and the number of stages using graphical methods / EXCEL / MATLAB / MATHCAD etc. Calculate and show the concentrations after each stage.

Separations Question It is desired to recover atleast 95% of ethanol from a mixture of ethanol and carbon dioxide (containing 98 % CO2 and 2 % ethanol) by scrubbing the vapor mixture with pure water. Assume equilibrium relation Y = 0.57 X. The gas stream enters the absorption column at 180 kmol/hour (V’) at 120 kPa (P) and 27 °C (T). The carrier gas may be considered insoluble in the solvent and the solvent may be considered nonvolatile. Assume dilute...

Problem #1 Saturated steam at 300°C is used to heat a counter-currently flowing stream of methanol vapor from 65°C to 260°C in an adiabatic heat exchanger. The flow rate of the methanol is 5500 standard liters per minute (at STP), and the steam condenses and leaves the heat exchanger as liquid water at 90°C. a) Draw a diagram of the process. b) Calculate the required flow rate of the entering steam in m3/min. c) Calculate the rate of heat transfer...
