A counter-current packed tower is to be designed to recover 90% carbon tetrachloride (CCl4) from an air-CCl4 mixture containing 5 mol% CCl4. The gas rate will be 800 kg/h m2 of tower cross section. A non-volatile CCl4-free organic oil of molecular weight 260 is to be used as solvent. The solvent rate should be twice the minimum. The tower will be operated at 30°C and 1 atm pressure. Under the operating condition, the equilibrium relation is given by y=20x, where y and x are mole fractions of CCl4 in gas and liquid respectively. If the gas and liquid phase mass transfer coefficients kya and kxa are 60 and 900 kmol/h m3 mol fraction, respectively, determine the height of the tower.

Assume dilute solution

Molecular Weight of CCl4 is 154 and Molecular weight of Air is 29.

Carbon tetrachloride, CCl4, was once used as a dry cleaning solvent, but is no longer used because it is carcinogenic. At 57.8 °C, the vapor pressure of CCl4 is 0.530 atm, and its enthalpy of vaporization is 33.05 kJ/mol. Use this information to estimate the normal boiling point for CCl4. please show work

A gaseous mixture containing 0.170 mol fraction of carbon tetrachloride (CCl4) and 0.830 mol fraction of dry air is initially at 61.0°C and 1037 mmHg. If this mixture is cooled at a constant pressure, at what temperature does the CCl4 first start to condense? At what temperature would 44.0% of the CCl4 condense?

The vapor pressure of pure carbon tetrachloride, CCl4, (molar mass 153.82 g/mol) is 0.354 atm, and the vapor pressure of pure chloroform, CHCl3 (molar mass 119.38 g/mol), is 0.526 atm at 316 K. A solution is prepared from equal masses of the two compounds at this temperature. If the vapor over the original solution is condensed and isolated into a separate flask, what with the vapor pressure of the chloroform be above this new solution?

A device has been designed to measure the flow rate of carbon dioxide evolved from a fermentation reactor. The reactor is sealed except for a tube that allows the generated carbon dioxide to bubble through a soap solution and into a vertical glass tube within internal diameter of 1.2 cm. On leaving the soap solution, the gas forces thin soap films stretched across the tube to traverse the length of the tube. Ambient temperature and pressure are 27°C and 755...

Saturated steam at 300°C is used to heat a counter-current flowing stream of methanol vapor from 65°C to 240°C in an adiabatic (no heat exchange with surroundings) heat exchanger. The flow rate of methanol is 400 kg/minute, and the steam condenses and leaves the heat exchanger as liquid water at 90°C. Calculate the required rate of heat transfer from the water to the methanol in kW. Then, calculate the required flow rate of entering steam in m3/min.
