A 100 mol/h liquid oil stream is 20% solute Q. We wish to reduce the concentration of Q to 1% by stripping it out with air. The air flow rate is 100 moles/h. The Henry’s Law constant for Q is 1.5. Find the outlet gas composition and the number of equilibrium stages.

You wish to remove solute Q from a heavy oil stream by stripping the oil with air. The stripper is expected to operate at 60°C and 2.2 atm pressure. At this temperature and pressure the oil can be considered to be nonvolatile and the air is insoluble in the oil. The inlet liquid flows at 100 kgmole/hr (total flow) and is 20 mole% Q. You wish to reduce the concentration of Q in the oil to 1 mole% Q. The...

(b) Propane must be stripped from an oil stream in a stripping column by using pure steam The pure oil stream (without Propane) has a flow-rate of 150kmol/h and is loaded with 2.5 mol% Propane. The column is set at the temperature of 350 K and pressure of 1.2 atm. The minimum propane amount to be separated is 90% (1) In order to determine the flow of the gas stream, some assumptions are used. What are the assumptions 3 Marks...

2. A gas mixture at 1.0 atm pressure containing air and solute A is contacted in a single stage mixer continuously with pure water at 30 °C. The two exit gas and liquid streams reach equilibrium. The inlet gas flow rate is 100 kg mol/h, with a mole fraction of A being 0.20. It is desired that the exiting gas contain an A mole fraction of 0.01. Calculate the flow rate of liquid required to achieve this separation. Assume that...

sol- A complete gas treatment plant often consists of both an absorber to remove ute from air and a stripper to regenerate solvent. Some treated air is heated and is used as stripping gas. In a particular application we wish to remove obnoxious impurity from inlet air. Absorber operates at 1.5 atm and 24.0°C where obnoxious impurity equilibrium is given as y ates at 1.0 atm and 92.0 C where equilibrium is y...

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...
