ANS:A - McCabe-Thiele method

The method that assumes constant molal vaporization and overflow is the McCabe-Thiele method. The McCabe-Thiele method is a graphical technique used for the design and analysis of binary distillation columns. It assumes that the relative volatility of the components remains constant throughout the column, as well as constant molal vaporization and liquid overflow. In the McCabe-Thiele method, the number of theoretical stages required for separation is determined based on the equilibrium relationship between the vapor and liquid phases, and the operating lines representing material balances for the distillation column. The method provides insights into the required number of stages, reflux ratio, and feed conditions for achieving the desired separation efficiency. The other methods mentioned:

• Ponchan-Savarit method: A graphical method for analyzing absorption processes in packed columns.
• Enthalpy concentration method: A method used for analyzing multi-component distillation systems based on energy balances.
• Plate absorption column: A type of absorption column used for gas-liquid contact in separation processes.

ANS:C -

The Kozney-Karman equation, which is valid for low Reynolds numbers (ReReRe), describes fluid flow through a packed bed of solids. It relates the permeability of the porous medium (packed bed) to the porosity and specific surface area of the particles. The Kozney-Karman equation is given by: ΔPL=150μ(1−ϵ)2ϵ3dp2⋅vρ\frac{\Delta P}{L} = \frac{150 \mu (1 - \epsilon)^2}{\epsilon^3 d_p^2} \cdot \frac{v}{\rho}LΔP​=ϵ3dp2​150μ(1−ϵ)2​⋅ρv​ where:

• ΔP\Delta PΔP is the pressure drop across the packed bed,
• LLL is the length of the bed,
• μ\muμ is the dynamic viscosity of the fluid,
• ϵ\epsilonϵ is the porosity of the bed (fraction of void space),
• dpd_pdp​ is the diameter of the particles,
• vvv is the superficial velocity of the fluid,
• ρ\rhoρ is the density of the fluid.

Explanation:

• Permeability: The term 150μ(1−ϵ)2ϵ3dp2\frac{150 \mu (1 - \epsilon)^2}{\epsilon^3 d_p^2}ϵ3dp2​150μ(1−ϵ)2​ represents the permeability KKK of the porous medium (packed bed).
• Superficial Velocity: vρ\frac{v}{\rho}ρv​ is the superficial velocity of the fluid.
